Dear All, I try to use our cluster though samba share. Everything work fine, but I think, we should have -o flock at lustre mount time. Great, it''s work. But when I want to save a file on the share, I get this on the logs: Jan 31 10:45:24 opteron-ren-11 kernel: LustreError: 24836:0:(file.c:2309:ll_file_flock()) unknown fcntl lock type: 32 Jan 31 10:45:24 opteron-ren-11 kernel: LustreError: 24836:0:(file.c:2310:ll_file_flock()) LBUG Jan 31 10:45:24 opteron-ren-11 kernel: Lustre: 24836:0:(linux-debug.c:171:libcfs_debug_dumpstack()) can'...

Hello! Please, help me, I''m totally lost choosing basic budget server for XEN. The variants are Sun (X2200 M2 or Sun X2250 M2) or maybe HP Proliant DL160 G5p. Or maybe some IBM server? Which X2200 configuration will perform better, two Opteron dual-core 22xx or single quad-core 23xx? Which one performing better nowadays, Opteron or Xeon? I know that 2-3 years ago Opteron was the better choice for virtualization, what about now? Is Xeon 54xx better than Opteron 23xx ? Thanks in advance! ___________________________________________...

I'm spec-ing a development server for some Haskell hackers. In particular, they need to be able to build and run the Glasgow Haskell Compiler (ghc), the x86_64 port of which isn't quite there yet. My current thought is to get an Opteron-based system, but load it (initially, at least) with the 32-bit i386 version of CentOS. That buys me near-term ghc compatibility. In the future, should ghc become 64-bit clean, I'll be able to upgrade to a full 64-bit OS. The alternative is to build the server around high-end ia32 chips and...

I'm only now realizing that we have severe problems with R on our AMD 'Opteron' and 'Athlon64' clients running Redhat Enterprise with all 64-bit libraries (AFAICS). The Lapack problem happens for R-patched and R-devel both on the Opteron and the Athlon64. Here are platform details: o "gcc -v" and "g77 -v" both end with the line gcc versi...

I am about to lease another server to be a backup web/mail server with a replicated mysql database. The current live server is a dual Xeon 2.8Ghz. Would I do better to get another Xeon server or an Opteron based server? My concerns are compatibility of the database and the SSL certificate currently running on the Xeon machine. Are these concerns unfounded? TIA Mike

Has anybody here taken a HDD configured with an Opteron system, and then put it into an Athlon/64 and had it work? Are they interchangeable, like an Athlon/32 and a P3/P4? -Ben -- "The best way to predict the future is to invent it." - XEROX PARC slogan, circa 1978

Hello, We have a few systems where udevd seems to failing silently on Opteron based Centos 4 boxes. Has anyone else seen this? -geoff

Dear R-help: Has anyone tried using R on the the AMD Opteron in either 64- or 32-bit mode? If so, any good/bad experiences, comments, etc? We are considering getting this hardware, and would like to know if R can run smoothly on such a beast. Any comment much appreciated.

Hi, I was wondering if anyone has had good experiences using R on Linux with dual AMD64 (Opteron) processors. I'm thinking of buying a couple of such servers, but I'd like to make sure R would work fine. The "R Installation and Administration" guide notes that there may be some problems with BLAS libraries. That's all I could find about R on AMD64. Please share your exp...

I am considering buying a Quad Opteron for asterisk, However i'd like not to buy one and see that it aint working ;) -> would asterisk compile for opteron ? -> would ilbc compile for opteron ? -> would the g729 license work on opteron ? -> would zaptel compile and run ? (TE410p) And if not, would it demand a lot of wo...

Hi I'm setting up a SIP gateway, serving quite a few potential users, and I wonder if I should purchase a Opteron or Xeon based system. Xeon has it's HT, but is it worth it? Has anyone tested Opteron on asterisk? Does it work well? There'll be no transcoding in this system - G.711A all way through roy

Anyone running Asterisk on dual Opteron Server? Are there any special issues in a 64 bit environment and what is the capacity curve like?

...E.g. what's the real cost of shipping data back and forth between the memory spaces of the two CPUs? How does the 2.6 kernel deal with the split memory space? etc...) The memory is all going to be used up in kernel buffers keeping bits of files in kernel memory. Also, trade offs between Opteron and Xeon architectures, i686 vs. x86_64, bounce buffers, etc., for an application like this would be helpful. The application is enhancement to a mirror server (mirror.cs.wisc.edu) here at UW-Madison. Many thanks to all in advance. Private or public replies welcome. Dave Thompson UW-Madison
