The release of knoppix was announced few hours ago but things like the kernel are added much earlier. Like days or weeks earlier. They're not added at the last minute, because distro maintainence is a tough job. And many times ditros contain not the latest version of programs available at the time of the release. There are a lot of reasons. On a side note, people who want infiniband will be able to update the kernel on the knoppix cd.

Google knows all.

Intell talks about Infiniband Architecture [intel.com]

Initially InfiniBand Technology will be used to connect servers with remote storage and networking devices, and other servers. It will also be used inside servers for inter-processor communication (IPC) in parallel clusters. Customers requiring dense server deployments, such as ISPs, will also benefit from the small form factors being proposed. Other benefits include greater performance, lower latency, easier and faster sharing of data, built in security and quality of service, improved usability (the new form factor will be far easier to add/remove/upgrade than today's shared-bus I/O cards).

Additionally, InfiniBand Architecture reduces total cost of ownership by focusing on data center reliability and scalability. The technology addresses reliability by creating multiple redundant paths between nodes (reducing hardware that needs to be purchased). It also moves from the load-and-store-based communications methods used by shared local bus I/O to a more reliable message passing approach.

Scalability needs are addressed in two ways. First, the I/O fabric itself is designed to scale without encountering the latencies that some shared bus I/O architectures experience as workload increases. Second, the physical modularity of InfiniBand Technology will avoid the need for customers to buy excess capacity up-front in anticipation of future growth. Instead, they will be able to buy what they need at the outset and 'pay as they grow' to add capacity without impacting operations or installed systems.

Virginia Tech used Infiniband to wire up their G5 cluster. It's basically very fast I/O with some good logic built-in - "The technology addresses reliability by creating multiple redundant paths between nodes (reducing hardware that needs to be purchased)." is basically the same as the change from linear, Token Ring-ish networks to big Ethernet meshes like the Internet. I don't claim to know much at all about this, but seemingly it's the superior alternative today, and it sounds like it should be as well.

what it is (4, Interesting)

r00t (33219) | more than 9 years ago | (#11823172)

Infiniband is a "smart" fabric; it supports reliable data transmission. Note that, as with modem protocols, this causes ugly interactions with TCP retransmits. TCP is really designed to work over an Ethernet-like network, where congestion causes packet loss and not much else bad ever happens.

You can use Infiniband as a LAN, for storage, or maybe for within a box. You could say that Infiniband starts where Hypertransport leaves off.

For the short-haul usage, Infiniband is kind of big in terms of chip real estate. You can't cram it into a corner of a little FPGA like you can with RapidIO. For the long-haul usage, 1 gig or 10 gig Ethernet might be a better choice.

Note that Intel, originally the primary sponsor behind Infiniband, no longer gives a damn. But hey, if you have money to burn...

Re:infiniband? (2, Informative)

TuringTest (533084) | more than 9 years ago | (#11822995)

Linked from the article:

Infiniband (define)

Both an I/O architecture and a specification for the transmission of data between processors and I/O devices that has been gradually replacing the PCI bus in high-end servers and PCs. Instead of sending data in parallel, which is what PCI does, InfiniBand sends data in serial and can carry multiple channels of data at the same time in a multiplexing signal. The principles of InfiniBand mirror those of mainframe computer systems that are inherently channel-based systems. InfiniBand channels are created by attaching host channel adapters (HCAs) and target channel adapters (TCAs) through InfiniBand switches. HCAs are I/O engines located within a server. TCAs enable remote storage and network connectivity into the InfiniBand interconnect infrastructure, called a fabric. InfiniBand architecure is capable of supporting tens of thousands of nodes in a single subnet.

InfiniBand is a trademarked term. The technology is a result of the merger of two competing designs -- Future I/O, which was developed by Compaq, IBM and Hewlett-Packard, and Next Generation I/O, which was developed by Intel, Microsoft and Sun Microsystems. InfiniBand was previously called System I/O.

InfiniBand transmission rates begin at 2.5GBps.

Anonymous Coward | more than 9 years ago | (#11822830)

...before the site is slashdotted...

The Linux world is bracing for the final release of the new Linux 2.6.11 kernel, which will include a long list of driver updates and patches, with InfiniBand support perhaps being one of most interesting new additions.

Late last night, Linux creator Linus Torvalds issued the fifth release candidate for the 2.6.11 kernel. The first 2.6.11 RC was issued on Jan. 12; the second on Jan 21; the third on Feb. 2; and the fourth on Feb. 12.

In the RC5 posting, Torvalds indicated that it was likely the last RC before the final release.

"Hey, I hoped -- rc4 was the last one, but we had some laptop resource conflicts, various ppc TLB flush issues, some possible stack overflows in networking and a number of other details warranting a quick -- rc5 before the final 2.6.11," Torvalds wrote.

"This time it's really supposed to be a quickie, so people who can, please check it out, and we'll make the real 2.6.11 asap."

The long list of updates in the 2.6.11 kernel includes architecture updates for x86-64, ia64, ppc, arm and mips, as well as updates to ACPI (define), DRI (Direct Rendering Infrastructure, which permits direct access to graphics hardware for X Window System users), ALSA (Advanced Linux Sound Architecture, which provides MIDI and audio functionality to the Linux), SCSI (define) and the XFS high-performance journaling filesystem.

The 2.6.11 kernel will also be significant in that it includes driver support for the InfiniBand (define) interconnect architecture. InfiniBand, which is derived from its underlying concept of "infinite bandwidth," is a switched fabric interconnect technology for high-performance network devices that is common in a number of supercomputer clusters.

The upcoming inclusion of InfiniBand support in the Linux kernel is a major step according to the InfiniBand Trade Association.

"The inclusion of InfiniBand drivers in the upstream Linux kernel is a significant milestone," Ross Schibler, CTO of InfiniBand vendor Topspin Communications, told internetnews.com.

InfiniBand support was available previously in various Linux distributions, but it wasn't part of the mainstream kernel.org Linux.

"This now means that anyone that downloads a kernel will have automatic access to the software," explained Schibler. "It also means that any upcoming distributions (Red Hat, SUSE, etc.) will have the software included on their CDs. Previously SUSE had it on a distribution, but only in the 'unsupported' directory."

Schibler sees the inclusion of InfiniBand as a testament to the maturation of the technology.

"Now that the technology has matured to such a point that Linus has accepted it into the kernel, the way is paved for greater distribution of the code and accelerated deployment of the technology," Schibler said.

The previous Linux kernel.org release, version 2.6.10 was issued on Dec. 24 after two release candidates. Linux distribution began including the 2.6.10 thereafter with Red Hat's Fedora Project being one of the first.

Fedora Core 3 initially shipped with the 2.6.9 kernel and then upgraded to the 2.6.10 kernel on Jan 13. Mandrakelinux's 10.2 Beta 3 also includes the 2.6.10 release. SUSE Linux 9.2 currently includes the 2.6.8 kernel.

Including the most recent kernel into a distribution is not a particularly easy task. The upcoming Debian, code-named Sarge, will only ship with the 2.6.8 kernel. In a release update e-mail, Debian Sarge release manager Andreas Barth related that a meeting was recently held to review the status of which kernel they would include.

"The team leads involved eventually decided to stay with kernel 2.6.8 and 2.4.27, rather than bumping the 2.6 kernel to 2.6.10," Barth wrote. "This decision was made upon review of the known bugs in each of the 2.6 kernel versions; despite some significant bugs in the Debian 2.6.8 kernel tree, these bugs were weighed against the additional delays that a kernel version bump would introduce in the schedule for debian-installer RC3."

"As it happens, preparing 2.4 and 2.6 kernels with the security fixes for all architectures took roughly two months from start to finish, during which time preparation of the next debian-installer release candidate has been entirely stalled," he added.

Re:Article text (1)

SCSI Permissions (0, Offtopic)

Anonymous Coward | more than 9 years ago | (#11822831)

This is off-topic but I'll ask anyway because a lot of people want to know.

I have to patch the vanilla kernel in the following way so that cdrecord works for non-root users.

I don't want to have to do this of course, because it's a potential security breach.

Question: is there a user space solution to this? Has anyone coded the Linux micro-permissions into cdrecord yet? Solaris is supported but not Linux. Is this a political issue?

Re:SCSI Permissions (0)

Anonymous Coward | more than 9 years ago | (#11823000)

Instead of burying his head in the sand why doesn't the moderator attempt to answer the question or leave it alone so someone else can.

The question is how can cdrecord be run as non-root in the 2.6.x series without patching the kernel? This is a serious issue. Not with the kernel itself but with the user land tools.

For me, it compiles fine - but it doesn't actually work. The driver isn't clearing the screen correctly - for example, I'll see the "login" prompt sitting directly on top of the Nvidia splash screen.

I just upgraded to a new ABIT motherboard, so the problem is likely related to the kernel's AGP workings of that, not the NVIDIA driver.

Maybe 2.6.11 will fix whatever the problem is. (I haven't nailed it down enough yet to supply a useful bug report.)

Re:someone tell nvidia! (0)

I think that Nvidia have to release a new version of the driver almost every time a new kernel is released, typically they do it pretty quick but it is a bit of an annoyance.

If they would just drop they're stance of open sourcing the driver will reveal trade secrets the kernel team could take on the driver development and things like this would be avoided

Don't know about 'more laptops' but yes, as long as you compile your own kernel and put all USB, wireless card, agpgart, and related stuff in kernel modules. Unload these modules before suspend and reload them after. Of course, that also means that your USB stuff needs to be unplugged before you suspend.

Why would I have to unplug USB devices if I want to just disable the software support?

Re:ACPI suspend? (1, Insightful)

Anonymous Coward | more than 9 years ago | (#11823303)

It should. The problem with ACPI is that many laptops are not true ACPI but merely work as ACPI with the Windows drivers. That means the Linux drivers have to emulate all the bugs and misfeatures in the Windows drivers to fully support all laptops. That reverse engineering process which must be done whenever a new non-working laptop is found takes time.

Atleast ACPI suspend (to memory) on my nx7010 started working in 2.6.11-RC3 , so a wild guess is that yes, more laptops are able to suspend with 2.6.11 vs. previous 2.6 kernels.

A kernel patch for supercomputers ? (5, Funny)

Gopal.V (532678) | more than 9 years ago | (#11822897)

TFA mentions that

>InfiniBand, which is derived from its underlying concept of "infinite bandwidth," is a switched fabric interconnect technology for high-performance network devices that is common in a number of supercomputer clusters.

So that works only for supercomputer clusters ?.

Interestingly, the ChangeLog has some very small number of entries. The one I found most fun was:-

Randy Dunlap:
o [ide] make 1-bit fields unsigned
I mean, other wise they would end up as "-1" or "0" (when you assume in code that "0" or "1" for 1 -bit fields). How did a sign-extension in the IDE (must be heavily used) be missed till version 2.6 ??. Typically, this looks like the average release - some bug fixes and a couple of big features which nobody (well almost nobody) would use on their boxes.

Tony Hoyle (11698) | more than 9 years ago | (#11823115)

I remember working with a guy who always added an extra bit to his bitfields 'because they always came out negative'. Somewhere in his (lack of) formal education someone forgot to tell him about unsigned ints...

When I joined he'd been working with the company for 2 years and was their senior developer. You can imagine what a state the code was in... I basically deleted the lot and rewrote it (which pissed him off no end but pleased all the other developers).

Re:Help? Wikipedia to the rescue! (4, Informative)

UnderScan (470605) | more than 9 years ago | (#11823097)

From http://en.wikipedia.org/wiki/Operating_system [wikipedia.org] :
In general, the operating system is the first layer of software loaded into computer memory when it starts up. As the first software layer, all other software that gets loaded after it depends on this software to provide them with various common core services. These common core services include, but are not limited to: disk access, memory management, task scheduling, and user interfacing. Since these basic common services are assumed to be provided by the OS, there is no need to re-implement those same functions over and over again in every other piece of software that you may use. The portion of code that performs these core services is called the "kernel" of the operating system. Operating system kernels had been evolved from libraries that provided the core services into unending programs that control system resources because of the early needs of accounting for computer usage and then protecting those records.
So that is the OS and the kernel. A new kernel version is new drivers and updated system services, which is a good thing. This is not the same as upgrading Win2000 to winXP or changing Linux distros as those involve many many more programs, libraries, & systems as compared (what is collectively known as an Operating System) to a kernel.

Generally the updated kernel is not useful to the average user, especially not for desktop users. The major updates that interested me were: the first bootable installation CDs, then the live filesystem CDs. If you have access the a high speed connection, try downloading "Live linux filesystem" distributions. These are great for learning and experimenting with. Good Luck!

Reiser4 (1)

thundercatslair (809424) | more than 9 years ago | (#11823012)

Does anyone know when reiser4 will be included? I use it on pretty much all my partitions and to use it I have to use extremely experimental kernel patches.

Re:Reiser4 (1)

Lussarn (105276) | more than 9 years ago | (#11823324)

extremely experimental kernel patches.

You pretty much answered your own question. I don't think anybody want extremely experimental kernel patches in the main kernel.

Re:Reiser4 (3, Interesting)

timster (32400) | more than 9 years ago | (#11823349)

Since reiser4 is in beta, I doubt it will be in the mainstream kernel particularly soon. It's going to be tough to use experimental filesystems without using experimental patches. I don't think anyone sane is storing important data on reiser4 partitions without doing extensive backups.

I hope the big memory leak I've been seeing with 2.6.10 have been fixed in 2.6.11. I had to disable HIGHMEM just to keep the machine running more than a few days, and that unfortunately means it's limited to 896MB LOWMEM.

brsmith4 (567390) | more than 9 years ago | (#11823104)

For those of you that are unaware, since the poster doesn't explain at all what Infiniband is, I will explain it for you.

Infiniband is a high-speed, low-latency interconnect used heavily with beowulf clusters (currently). Infiniband, like Myrinet, addressed many of the problems that are inherent with using interconnects like ethernet.

The biggest problem with any TCP/IP based transport, in the world of supercomputing, is latency. The amount of error checking that is involved creates latencies that bring fine-grained (lots of memory reads/writes/swaps) calculations to their knees. As many clusters use MPI (Message Passing Interface) for sharing memory between nodes, a low-latency interconnect was needed to replace ethernet and TCP/IP. People have worked on reducing latencies over ethernet by designing raw transport stacks, relying on the switch and the quality/brevity of the ethernet connections (using short, shielded cables proved useful), to ensure accurate data transport, but none of these methods have proven viable.

Infiniband has also been used as an interconnect for network storage devices as there are obvious advantages to this; eliminating much of that latency makes reads and writes to a device much simpler thus reducing overhead and improving overall throughput.

More information on Infiniband can be found here [sourceforge.net] at the Infiniband sourceforge page. This should give a sufficiently technical overview of what it does without any of the marketing talk.

psmouse.c (2, Informative)

MrNemesis (587188) | more than 9 years ago | (#11823124)

Does anyone know if any work is being done on the rather irritating problem I (and a fair few others) get with the 2.6 input system? Every time I use a mouse that goes through a KVM switch or a USB->PS2 adapter, the mouse would spazz around crazily and syslog would fill up with:

lost synchronisation, throwing [1|2|3] bytes away

Adding psmouse.proto=imps made the problem go away for most usage, but it still occurs under very heavy load, which makes mplaying UT impossible :(

Re:Show of hands... (1)

cswiii (11061) | more than 9 years ago | (#11823345)

Even worse, I've been scratching my head, trying to get 2.6.10 to work.

Until recently, I was running, compiling 2.4.x kernels with no problem; I then moved to FC3, and for the first time, was using 2.6.x kernels, and first time using grub.

2.6.10 builds for me, and everything. I build the kernels, build and install the modules, and since I have SCSI, I run initrd; I add the kernel and initrd.img line to my grub.conf. However, I still get a kernel panic telling me that it can't find the system at boot...? I have checked and triple-checked my grub.conf -- it's pointing to the right files. Regardless, doesn't work, even when I rebuild with SCSI builtin, as opposed to a module. Doesn't make any sense at all.

Regardless, I'm compiling 2.6.11 as I type this... :P.

ChangeLog (2, Informative)

Sunspire (784352) | more than 9 years ago | (#11823393)

The linked changelog is only the changes between 2.6.11-RC5 and the final version, that's why it's so short. Is there a complete changelog available somewhere?

Also, does anyone know what the status of inotify support is? I think a lot of people would be glad to see it merged, as apps like Beagle require it and the new Gamin daemon (a FAM replacement) should work much better with it.
