problem with paralell computing
I use a quantum chemistry program called Gaussian 03, which I run on a cluster of computers. The cluster consists of a main node plus 11 other computers (nodes). Gaussian uses software 'linda' for paralell computing.

Often my job (process) will freeze - which I can get running again by pressing ctrl-c.
On closer examination, I found that the job freezes when one of the subprocesses becomes defunct. This leads to the master node not communicating to the other nodes and hence freeze in calculation. ctrl-c probably kills the defunct process and gets the calculation running again.


It is a big hassel and waste of time to press ctrl-c every few hours. What can I do about it?
Thanks.

Do you need an advice how to build a script who will simulate press of "Ctrl+C" ? You should report this issue to the respective software developers.

I favor sysgate's second answer. You may be losing data with ctrl/c as well.
This is definitely a vendor problem.
