Recent kernel SMP scalability Benchmark/White-paper References.
I was looking around on google web, google groups, lkml digests, Intel.com, RedHat, SuSe, SGI.com, osdl.com, etc for some benchmarks of recent 2.4.x kernels, say 2.4.x > 16, with references to SMP scalability problems or successes, etc. Mainly centering around 4-way/8-way x86 testing in terms of memory bandwidth/utilization, threading performance, etc.
I've not found much in my search so far, and thought at this point it might be best to ask on this list to help shorten the search a bit, if possible. Of the documents I do have, they're more marketing based and not really *technology* based or touch very heavily as to generic benchmarking of a standard Linux kernel on SMP.
I'm hoping to create a white-paper internally, and hopefully externally at some point, which can be maintained so others don't have to do the same arduous task of trying to find recent data as it pertains to said statistics.
Any help as to recent documentation of this nature would be *overly* appreciated!
In addition to this info, I'm trying to gather information as it pertains to the scalability of Linux kernels on 4/8-way x86 systems versus Solaris Sparc 4/8-way systems with measurements of the same statistics.
I fear I'm searching for a document which does not exist. TIA.
Hi Austin,
Check out http://lse.sourceforge.net
and http://sourceforge.net/projects/lse
(lse= linux scalability effort)
That might be more information than you were looking for. Another good resource is the lse mailing list at:
[email protected]
We have bi-weekly conference calls where anyone is welcome to join and ask questions or report your work or whatever.
As a developer working on SMP scalability on Linux I would say it is getting better but we still have work to do.

Kewl, I might just see if I can work that in. I saw the LSE, but the documentation out there hadn't been updated in quite some time as well. Same with the SGI Linux Scalability Project. It is old, and seems to center around only MIPS. :(

I have updated some 8-way kernel comparisons running dbench as recently as a couple weeks ago. Although, I do not know of any specific Linux(TM) vs Solaris(TM) benchmark results on the lse web site. ;) What benchmark would reflect your workload?
Speaking of OLS, Is there any interest in an lse-tech BOF or get- to-gether of some sort in Ottawa this summer? It would be nice to put some more faces to names from the conference calls.

Same LTC, different state. The LTC engineers live all over the world. I know some of the guys in Austin...

Kewl again. I didn't see them, but thanks anyway. I'll check them out.

I wish. My company doesn't *send* me anywhere. :)
One last question for the list. Is there a recent 2.2.x vs. 2.4.x SMP kernel comparison available as well? Recent can be as much as 9-10 mo ago, preferably younger though.

All I've found so far is:
which is based on the 2.2.14-SMP -vs- 2.3.99-SMP kernels.

I'm hoping to create a white-paper internally, and hopefully externally at some point, which can be maintained so others don't have to do the same arduous task of trying to find recent data as it pertains to said statistics.
If you find anything else, or get forwarded any information, please post the relevant information where possible. There are many of us looking for benchmark information on recent 2.4.x kernels. Seems like a few companies/projects are currently looking at the costs/benefits/risks of moving up to the new kernel.

Yeah..been there, done that. Most stuff I've found is no newer than 2000. :( I really need something recent.

That is the plan. Like with my recently completed Multi-Realm Kerberos install docs that I've been working on, everything I collect will get out for public knowledge.Sharing our experiences is the only way to make the world a better place.
