Senthil,

Thank you for replying, I knew that is the simplest way to achieve the goal of claiming only 1 CPU but if I configure the startd machine that way I will only be able to utilize one CPU at out of 4 it has available, this user only submits jobs 3-4 times per week so whenever he send his jobs I will have to stop condor on that machine, change the configuration, submit the job, wait for to finish, stop condor again, then change again the condor_config to advertize all CPU’s so, it is way too much work and I will be limiting the machine ability to be utilized at the most efficient way. I think I found what I need in the How-to-Admin-Recipes what I want, http://condor-wiki.cs.wisc.edu/index.cgi/wiki?p=HowToAllowSomeJobs. I need to claim the whole machine for these jobs. I am having some issues dissecting how to apply the article and make it work but that is another story thanks anyways again.

Respectfully,

Hi,

Having NUM_CPUS = 1 in condor_config will do what you are trying to do.

Good Luck.

Subject: [Condor-users] Allocating memory and cpus per job

Hello to all,

I need to run an specific type of job on a windows pool, the machines are 64 bit windows 7 boxes with only 2 GB memory total, which you all know the memory splits equally 511 MB per CPU’s. This particular kind of jobs are memory intensive so it usually shallows up to 2 GB. Is there to only claim 1 CPU per machine and allocate all the memory for that job only? I’d been reading the manual and I don’t seem to be going anywhere, maybe if I can be pointed me to the right direction or can simply tell me this cannot be done, I really appreciate the advice. I know I can limit the memory at the machine level from the condor_config file but this pool serves a medium size group of users that mass process jobs and require to utilize all the processing muscle of the farm. Any input\help is welcome and I thank you in advance for it.
