Dear Experts, I know there are many HPC (high performance computing) experts on this list. I'd like to ask your advise. Almost two decades ago I chose to go with OpenPBS (turned down condor and other alternatives for whatever reason) for clusters and number crunchers I support for the Department at the university. It turned out to be not bad, long lived choice. At some point I smoothly

Dear Experts, Could someone recommend some "quick and dirty" HOWTO on condor based cluster? A did a bunch of cluster setups, I always used PBS (or torque lately). But my professor wants his to be Condor. I started reading Condor documentation, and it is vast. And quick route, like: architecture chart, and parameters I need to configure on master/submit, and compute nodes - somehow

I need to serialize computing job requests for two different multicore machines, and in some near future, for a cluster. I have worked with SGE but it requires NFS and other administrative steps, plus it seems a bit overkill for my needs. I guess some simpler queue managing engine may have been developed, possibly over SSH. Any pointers? TIA. -- Eduardo Grosclaude Universidad Nacional del

Anyone know how to submit jobs to at or anything else that allows jobs submitted to a queue to be executed consecutively? I have a series of servers that submits a job via an ssh background job but I can only have one execute at any given time. Possibly some clever bash work? Thanks! jlc

Hello , Centos users: My name is Leandro, I have been using Centos for 4 years and this is the first post in this mail list. I would like to study and introduce myself in clustering and high availability for Centos, currently I have not experience at all about it. I would like to ask about the newest method to achieve high availability , load balancing on linux / Centos. So far I have seen the

Hello, I would be extremely grateful if anyone is able to provide any (rather obscure) advice on using R with Condor. I think I'm following Xianhong Xie's instructions (R News 5(2) 13-15) correctly, but my job just stays held in the queue (for days / months). I've checked condor_status to make sure there are plenty of machines available, but can't see any way to attack the

Hi all, I'm happy to announce a new tutorial! https://alteeve.com/w/2-Node_Red_Hat_KVM_Cluster_Tutorial This tutorial walks a user through the entire process of building a 2-Node cluster for making KVM virtual machines highly available. It uses Red Hat Cluster services v3 and DRBD 8.3.12. It is written such that you can use entirely free or fully Red Hat supported environments.

Hi Everyone, I have group of R jobs that should be submitted to the condor when I submit the jobs to the condor, they don't run and when I checked the Sched Log files the jobs are exiting with status code 10. Previously, the jobs ran well on condor but now when I submit the jobs on condor they aren't running.Can anyone explain the meaning of this? Here is my submit file: # Submit file

Hello dear R-help group (and David Smith from REvolution), I would like to perform parallel computing using R with Condor (hopefully using foreach or other recommended solutions, if available) for some "Embarrassingly parallel" problem. I will start by listing what I found so far, and then go on asking for help. So far I found the a manual by Xianhong Xie from Rnews_2005-2 (see page

Hi, I was wondering if anyone has successfully linked R against the Condor libraries so that R can be run as a Condor job in the "standard" (not "vanilla") universe. The advantage of this would be that due to checkpointing, jobs can be suspended and transferred to another node. There is a good overview by Xianhong Xie here:

Hello all; I'm trying to execute parallel jobs trough library snow on a cluster built through torque/PSB. I'm succesfully obtaining the cluster with: >system("cat $PBS_NODEFILE > cluster.txt") >mycluster <- scan(file="cluster.txt",what="character") >cl <- makeSOCKcluster(mycluster) The only problem, at the moment, is that if I use

I've searched both the archives and dejanews, to no avail. I'm trying to get a hp 4mp (PostScript) print out sane output. I've got a old machine running Red Hat Linux, hooked up to the 4MP. The printcap prints up postscript just fine. I make the printer a share, tell it that the printer is postscript, then go to the win98 box, choose the HP 4MP driver and try printing and get

I have a data set covering a large number of cities with values for characteristics such as land area, population, and employment. The problem I have is that some cities lack observations for some of the characteristics and I'd like a quick way to determine which cities have missing data. For example:

Hi all. I am currently working for a hosting provider in a 100+ linux hosts' environment. We have www, mail HA solutions, as storage we mainly use NFS at the moment. We are also using DRBD, Heartbeat, Corosync. I am now gathering info to make a cluster with: - two virtualization nodes (active master and passive slave); - two storage nodes (for vm files) used by mentioned virtualization nodes

[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

Hello, I have several systems which I recently updated with yum -y update to all the latest packages. These systems use yum-priorities and use the CentOS (priority 1) EPEL (priority 5) and rpmforge (priority 10) repositories. After the updates, dhcpd stopped working with a SIGPIPE error which occurs shortly after it attempts to fork into the background. I worked around that problem by building

In the first line, use the dist function, found in library mva, to get the distance between each pair of rows. From this calculate an incidence matrix for which element i,j is true if row i in dat equals row j in dat (and false elsewhere). In the second line, for each row calculate the indices of the matching rows and take the minimum of those as the key. incid <-
