[Sorry for possible duplicated thread.] Hi. I''m new to Xen and I would know if it works well in a cluster environment (Beowulf, OpenMosix, CoLinux etc). I need an HPC running some virtual machines. Is this possible with Xen? Regards. -- Allysson Steve Mota Lacerda Administrador de Redes http://www.stevelacerda.net _______________________________________________ Xen-users mailing

Hi all !!! I have got a MOSIX-Cluster and wanted to upgrade to ext3-fs, but that didn't work out. The ext3-fs patch FAILED to patch the MOSIX-kernel and if I tried to apply the ext3- patch before, the MOSIX-patch failed. Can someone help me with that ? Perhaps someone knows of a conclusion for that problem or can tell me where to get a MOSIX-patch for 2.4.15. I would be glad to hear from

Hi All, Can i install * on a beowulf cluster or Is * compatible to clusters. I am planning to install a 4 node beowulf cluster using few cheap hardwares. If no one had tried before i can spend some time on installing and configuring * on this cluster. Let me know. thanks, -Balaji --------------------------------- Do you Yahoo!? New Yahoo!

Hi there, We're currently attempting to explain a slowdown of an LVQ-type parallel analysis we're working on. We are benchmarking our analysis running over openMosix against the same running via SNOW for R. Both perform similarly on small datasets, but on large datasets SNOW drastically outperforms openMosix. However, these results are achieve running SNOW on the default RedHat

Mosix is a cluster operating system that is a set of kernel patches to Linux on i386 machines. It allows processes to migrate to other nodes on the cluster transparently. See www.mosix.org for details. However, my R processes were refusing to migrate. Using strace, and delving into the R code, I found that it was due to a large number of calls to the system setjmp and longjmp routines - the

Barry, Would you mind providing the necessary patch for this behavior?

Hi All, I have posted this messgage yesterday in the Beowulf mailing list, and did not get any responses, as i have tried different Centos kernels to see if the behaviour changes or not, and it did not change much, I am posting it here, I hope no one minds, and thanks in advance for any pointers or clues? ---------- Forwarded message ---------- From: Walid <walid.shaari at gmail.com>

Hi, does anybody know how to use the dual processors in the machines of a cluster? I am using R with rpvm and snow packages. I usually start pvm daemon and add host machines first, and then run R to start my computing work. But I find that only one processor in each machine is used in this way and the other one always stays idle. Is there any simple way to tell pvm to use the two processors at

Caveat: I've only played with this a couple of years ago... I believe you can just add each host _twice_ (or as many times as the number of CPUs at that host) to get both CPUs to work.

Dear Friends, I'm trying to learn to use parallel computation using snow & rpvm Now, I have two boxes: 1) Pentium 4, pvm 3.4.5, R 2.2.0 with FreeBSD 5.4 (box uffbsd); 2) PowerPC, pvm 3.4.5, R 2.1.1 with Debian Linux latest stable (box powerpclinux); I'm using the instructions in (found in snow.pdf) http://www.stat.uiowa. edu/~luke/R/cluster/cluster.html. Now ** from the box

Hi all, I was hoping to get some advice about a problem that I realize will be difficult to reproduce for some people. I'm running R 1.7.1 on an openMosix (Linux) cluster and have been experiencing some odd slow-downs. If anyone has experience with such a setup (or a similar one) I'd appreciate any help. Here's a simplified version of the problem. I'm trying to run the

Has anyone tried Asterisk on a MOSIX cluster? My concern is if there is any adiitonal laltency when when the processes are moved from on node to another. Anyone tried it yet? thaks, darran ps. Anyone have any info on MYSQL support with Asterisk? I see the conf file but I dont see a database schema to install... -------------- next part -------------- An HTML attachment was scrubbed...

This is a rather obscure question, I realize. I have written to the package author but have not heard back as of yet. I have read the README in the package, as well, but it didn't give me enough detail to diagnose the problems that I am having. (I did edit out the LAM-MPI check in zzz.R.in.) I am working to install Rmpi on top of MPICH on a beowulf cluster. Below is the output of the

Hi I am after a solution where i can easily kickstart many, read hundreds, of boxes in a short time frame. Perhaps the way i install software is to actually re-kix the box with a new software baseline - that type of idea. I have looked at rocks and it looks good but it seems a little rigid in that i need to be able to determine certain things like hostname etc as in our env hostname

Dear R-help, Has anyone tried running R on a Beowulf-type cluster? I can get R to run in batch (using R CMD BATCH) on a cluster, but am wondering if it is possible to get an interactive R session on a compute node. Right now, if I run: beorun --nolocal R I just get the R start-up message and back to the shell prompt. If I try bpsh 0 R I can get R started (but the R prompt does not

Dear r-help, I am having an intermittant error using R on a linux beowulf cluster. I am using my homebrew script to test the performance of various feature subsets with "lda". ------------- The general procedure is as follows: I load the data from an .Rdata file (which has generated by R-1.3.0) run my script "Iterate()" ... At a different iteration each time I get the

Greetings. In looking through the mail archives, I don't see any mention of parallelism of the vorbis code (particularly the encoder). I was wondering if anyone was looking into this at all? Either with threads, and/or on some kind of parallel machine (e.g., a Beowulf cluster)? I see very little mention of threads in the source code, which leads me to believe that they are only there for

Hi Everybody, I know that R has snow package which can be used for Parallel Computing. However, every time I try making a cluster, the only type of cluster I'm able to make is the "SOCK" (that too because I disabled the firewalls). For the rest (i.e. MPI, NWS, and PVM), I get error every time I try making one. I get the following errors

Hi, all. I'm running R on a beowulf system, with software that can take a list of single-processor jobs and parcel them out over the system. (In case it's of interest, they're dual pentium 866 machines connected by fast ethernet.) The administrators of the system found that I was causing a huge load on the file server, and when they investigated it turned out that each process was
