[Bioclusters] Application not writing to disk with OpenMosix

[T. Grzybowski]

Question:  We are running an application called NONMEM on a small 
OpenMosix cluster.  We  use the "system" call under perl (together with 
"&") to spawn a few hundred tasks at a time.  Each tasks is spawned with 
the present working directory set to a unique ID.  The problem is that 
although the tasks seem to run OK (reading their input data running for 
a while and all), the output data files (in the PWD) are empty.   I am 
not using the oMFS, but relying on the home node to handle all IO.  
Anyone have relevant experience with NONMEM or R who might be able to 
give me a clue to the problem?

Thanks,
Thomas Grzybowski
