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?

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 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.

Hey Group, We are trying to build a shared disk, shared cpu, shared ram....using a dell power edge servers.....which can utilize our server resource for our expanding website. We are running RHEL4 on dell power edges. Can anyone suggest any good production ready open source solution running on top of 2.6 kernel that might work for us? I have looked at openMosix which has only 2.4 kernel

All, What is the state of SSI (single system image) on CentOS 6/7 these days? I'm interested in this at present just for the fun aspect of trying it. Obviously openMosix is no more, but OpenSSI, Kerrighed and LinuxPMI appear to be dormant. TIA, Steve

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>

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

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

Hello dear R-users, I have a tricky problem of data manipulation with R. Although it seems very easy, I can not solve it by myselves. The problem is a variable in my dataset is usually be readed as "factor" (variable mode), however I want it be a "numeric" one. I want to know how can I define an variable/column in a dataframe as numeric mode, after I imported a large

Hi *, I spent two days to try to solve the following problem without success... (google, archives, ...) Platform: RedHat 9 (OpenSSI cluster) with Samba 3.0.6. The server successfully joined a domain and act as a file server. winbindd runs to map users between the NT & Linux world. wbinfo [-t|-p|-u|-g] -> ok getent passwd -> ok I can successfully see all the Windows users as

I'm using rsync 3.0.9-1 in Cygwin to copy several directories to 32GB micro SD cards in both WinXP and Win7. I randomly get this error message; Please help me to debug it: rsync: writefd_unbuffered failed to write 127 bytes to socket [generator]: Broken pipe (32) I'd first posted this to the Cygwin mailing list with no response after almost two weeks (and sent a reminder after one week).

Hi All, I have looked through the following thread: http://tolstoy.newcastle.edu.au/R/help/02b/4551.html and would like to ask after 1.5 year the same question: Are there any plans to involve multithread computations in R? Few word about my motivation: I use R on my OpenSSI cluster with 7 CPUs, so one could simply think of this cluster as of single computer with 7 CPU. My

Any dedicated server hosts here offering Intel-VT-based servers? I''m thinking about standing up two Xen hosts in two different geographical locations and it''d be great if I could run either Windows or Linux on an Intel-VT-based processor (rather than using VMware on a standard processor). Might like to run either Debian, Ubuntu or SuSE as the Dom0 OS. CD

Attached please find updated build and publish scripts. They set the ''ulink.target'' parameter appropriately when converting docbook->HTML. I have always hacked my xhtml/params.xsl file to set this parameter; these updated scripts make that abomination unnecessary. Paul/Mike: It might be a good idea to add a CVS project for these scripts. -Tom -- Tom Eastep \ Nothing is

I''ve been brainstorming... I want to create a 2-node HA active/active cluster (In other words I want to run a handful of DomUs on one node and a handful on another). In the event of a failure I want all DomUs to fail over to the other node and start working immediately. I want absolutely no single-points-of-failure. I want to do it with free software and no special hardware. I want

Hello, If one would like to build a redundant Asterisk setup, would it be possible to exchange the locationdb for the SIP users between then? IE, the following setup: SIP Phones -------------- Asterisk ------------------------ SIP carrier | | ------- Asterisk (standby) ------ Asterisk is used as a PABX in this setup, so the

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.
