To do multi-processor calculation, I increased Nproclinda=3 ( we have four nodes, each with 2CPU) and kept the same memory request or less (8mw), initially the job really went to other nodes, however after a while it crashed regardless of jobs running or idle in other nodes. The error message read like this, Linda panic on node master.cl.usc.edu: No more memory for Tuple Space 9sbrk() failure) forrtl: error (76): IOT trap signal Fatal: ran out of heap space ntsnet: master process exited with return value 1 Thanks for your help.
