similar to: Using log() on an openMosix cluster

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

Hi there, We're attempting to run an LVQ analysis over a cluster of machines via R and openMosix. R spawns several child processes simply by writing commands to several files and using system() to start a slave process. The processes migrate perfectly, and often finish with no reported errors, writing their results into respective files for the parent process to piece together.

Memory could be an issue. The three nodes in the cluster we are using only have 512 MB. The machines are otherwise identical in terms of hardware. They are dual PIIIs (purchased from Penguin Computing in 2001). (If you need specs on motherboard etc, we can get that info together.) The installed operating system is RHEL-3, standard workstation with some additional libraries (e.g., all of the

It's generally said that OM needs lots more swap than plain Linux. There has to be someplace to juggle processes around. We use 4 GB nodes with something like 12 GB swap; that plus round-robin logins to distribute home nodes seemed to solve a lot of our problems. To use oMFS to allow processes to write from the node they've migrated to you also need DFSA enabled. That sounds like a great

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

One problem with Wine has been that there were few serious open source win32 applications out there to test Wine with (ok, maybe my opinions are from 1997 :-) In any case, we have some great open source Win32 applications to test with. AbiWord is one. I just tried installing AbiWord 0.9 under the latest Codeweavers preview. The install worked -- but generated about a billion warnings of 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...

I just spent one hour tracking the newest instance of the bug. At the end of it I found a workaround and a new direction to search for it. I remind everyone that the machine is a Slackware box with a 2.4.23- vanilla kernel.

Anyone have any experience running OpenMosix on CentOS 3? Are you using a kernel custom built or from somewhere? Any maintenance headaches wrt kernel updates? Thanks in advance. -Alan -- Alan Sparks, UNIX/Linux Systems Integration and Administration <asparks at doublesparks.net>

Hi, This is not an R question per ce, but I feel like this is a right community to ask it. As a part of our work we run a lot of non-interactive computational jobs. To increase the throughput we would like to distribute the load over the entire network and we are looking at Linux network as a platform. Ideally we would like to be able to submit a job to the network, rather than to a computer, and

Apologies if this is the wrong place to post this question. In that event, please point me in the right direction. My question is whether or not I can use Xen with OpenMosix. The upshot of what I''m attempting to do is this: 1. Build a two to four node cluster using OpenMosix for "raw horsepower" 2. Use Xen on the OpenMosix cluster to divide the "raw horsepower" any

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

Dear all, I wrote the following batch script on a iMac, and ran it on a linux mosix cluster. tu <- read.table("cage.mm5.tags.rna_lib.CAA-CAJ.tu-reshape.table") tu_reshaped <- t(reshape(tu[1:50,], direction="wide", timevar="tu", idvar=c("rna","lib"))) write.table(tu_reshaped, "cage.mm5.tags.rna_lib.CAA-CAJ.tu-reshaped.table")

Hello fellow samba users, Our company uses samba for all fileshares/printing/PDC on two SUN E3500's. We like to replace these with about 10 Linux 19" XEON (pizza)boxes.
