I've discussed this a little with Ian off list, but relating to: https://fedoraproject.org/wiki/Features/Condor_Cloud Condor Cloud aims at setting up a bunch of Fedora nodes to act as a mini-cloud managed via the Condor grid infrastructure. So the natural question was... Why not use oVirt Node for this rather than a full Fedora OS install? Pulling condor-cloud and condor RPMs into the core oVirt Node will...

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 problem of the non-r...

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 subm...

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 13) Talking about R and...

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: http://cran.r-project...

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 -...

Hello all, Recently I started playing with running R scripts on the Condor system in my institute. (For more on this, have a look at: Running Long R Jobs with Condor DAG by Xianhong Xie link: http://cran.r-project.org/doc/Rnews/Rnews_2005-2.pdf ) Might someone advice me about the following question: How should I handle the RNG (random number generation) in the running o...

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 migrated to torque which was advertised as open source project (based on PBS, but it was much l...

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

Dear all, We have started using R for data analysis since a few months and find it useful. We are planning to acquire a high-end dedicated system for microarray data analysis and thinking of a distributed environment. I would appreciate if some one could send some pointers regarding how to choose a proper hardware configuration, software (R or other software, esp. MATLAB), issues on setting up

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

Hi All In the past I have worked with parallel processing in R where a function F is applied to the elements of a list L. The more cpu cores one has, the faster the process will run. At the time of launching the process for (F,L) I will have a certain fixed number of cpu's that I can use. I have tested this approach and it works fine (i.e. package 'multicore' , using 'mapply'

All, We are researching approaches to parallel R with the end goal of running R in a distributed manner on a Linux cluster. We expect of course to do some work decomposing our problems to be task-parallel or data-parallel, but wouldn't mind getting an initial boost working with "embarrassingly parallel" code sections and one of the approaches below. Incidentally our environment

Hey folks, I just went through the archives trying to find some info on this but did not come up with much other than it seems there are a few experts here on the list. I have no experience with clustering and have just taken over a Stem Cell Research Lab that has a Grid Engine cluster. I have not yet dug into the details of Grid Engine (only been here a week now) but am just trying to get up
