Re^3: Running Parallel Perl Script on Linux Cluster

...you will have to poll from time to time to see if all the result files exist or if "fail" files are there, to requeue the jobs.

Hi salva,

Thanks for the answer. Roughly, I suppose that one would use glob to check the file (fail or not)? But not sure how to 'reqeue' the jobs.

Can you give a simple example how would one do the above step as you suggested?

Regards,
Edward

the best way to check if a file exists is with the `-f` operator (it is documented in perlfunc). To requeue a job, you would need to run the corresponding `qsub` command again, ensure that you delete the "fail" file first with `unlink`.	[reply] [d/l] [select]

Hi monkfan, Can you share how the code worked? I'd like to try out a variation on a 32 proc cluster in a classroom environment. Thanks! vanallp	[reply]
