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. However,...

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 way that I need it I am specifically interested in setting up two or more...

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 kernel (Enterprise Edition, RHEL-3) and mosix on the same kernel patched with...

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 following code: ## N <- 100000; a <- numeric(N); b <- nu...

Hi, Has anyone used a 2.4 series kernel on RHEL4/Centos4? There's a patch (openmosix) which I would really like to make use of [seeing as I just got 10 diskless computers...] which is not ready (yet) for the 2.6 kernel series... Can I just drop in a 2.4.26 series kernel and continue to have a working system? Or is RHEL now totally dependent on 2.6 kernel features? Cheers, MaZe...

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>

Any thoughts on running Xen on OpenSSI? We have an app we''d like to cluster but is expressly and completely incompatible with the OSes that OpenSSI are supported on, but if we can run several Xen domains on a cluster we can run those OSes and, naturally, that app. Thoughts?

...uel A. Mota Jr., Co-Founder and President of the Woodrow Wilson High School Science & Technology Club in Camden, New Jersey USA. With a few small grants from Lucent Technologies/Bell Labs, we have developed a parallel-processing Linux Cluster (6 nodes) based on Red Hat 7.3 (2.4.18 kernel ) and openMosix clustering technology. Its not much, but its a modest start for a few minority teenagers in a urban city helping in the movement for Open Source software. We are using the following applications: KFract, KMandel, WideStudio, KStars, and POVChem. In terms of benchmarks, we are currently using POV...

...ncing Quantian release 0.5.9.3 =================================== I What is it? Quantian is a remastering of Knoppix, the self-configuring and directly bootable cdrom/dvd that turns any pc or laptop into a full-featured Linux workstation, and clusterKnoppix, which adds support for openMosix. However, Quantian differs from (cluster)Knoppix by adding a large set of programs of interest to applied or theoretical workers in quantitative or data-driven fields. See http://dirk.eddelbuettel.com/quantian.html for more details. II What is new? o Third release b...

Quantian strives to provide the easiest way to set up a very complete scientific computing environment with a wide variety of tools -- including R, ESS, Ggobi, almost all of CRAN, all of BioConductor, as well as openMosix support, and many more applications -- in minutes from a bootable dvd. Feedback is always welcome, in particular on how to communicate more directly with specific communities which may benefit from Quantian.
