qsub pvm job
Hello, I am new member.

I am using pvm. My program is working as I start it with ./myprogram command but when I put it to cluster of computers which I am not allowed to control(system manager does) with qsub myprogram program does not start working and it does not give any error message, just hangs there, no output, no message, I do not know what to do

Hi and welcome to LinuxQuestions!

Can you see your job using qstat -a? What if you try to submit a simple job like the following?

date >> $HOME/myjob.log

vunal 10-25-2010 08:22 AM

yes I can see my job as I write qstat -a

Is it in a running (R) state or it's hold/queued (H/Q)? Did you try a more simple job like the one I suggested to see if it runs flawlessly?

vunal 10-26-2010 02:59 AM

it stays in R position, I tried a simple program and it worked without a problem, I use PBS when I put my job with qsub. May be I have to define something in the pbs file related to pvm?

AFAIK there was never a tight integration of PVM into PBS/Torque, there is one for GridEngine though. The problem is, that first the virtual machine of PVM must be started on the granted nodes - you request more than one CPU in your `qsub` command?

Nevertheless: how do you test you program locally? You started PVM's virtual machine on your local machine beforehand? Then we would need to start the virtual machine inside the cluster inside the granted nodes.
