Re: Fwd: Re: System Command Not Executing

I was told that the system has 8GB of RAM installed on each node.

compute-0-0 >free -m
 total used free shared buffers cached
Mem: 7990 879 7111 0 71 373
-/+ buffers/cache: 434 7556
Swap: 996 41 954

If the script has enough memory to create the arrays, then it doesn't
make sense to skip over the system commands.

Thanks, Michael
