I have been using G98 on a quad core machine for a number of years. This is a
32-bit version of the program. One has to assign memory to the 4 processor with
a command like: echo 356515840 >/proc/sys/kernel/shmmax, and add the line
Nprocs=4 to the input. I am visiting a lab that has G03 installed on a 64-bit
machine. It seems to be running ok, but things are different. On the 32-bit
machine I can see 4 processors running with a ps command. On the 64-bit machine
I see only 1 l502 job. Is this normal? Also it doesnt seem to be necessary to
divide up available memory on the 64-bit machine. Why is this?
