I am using common blocks in an old F77 code that I am converting to MPI. I notice that the memory does not seem right however. This is what I meen. All of my vars are static and are in common blocks. The bounds of these are in the common blocks. But, when I use top I notice that . PID USER PRI NI SIZE RSS SHARE STAT LIB %CPU %MEM TIME COMMAND 2013 matt 12 0 19580 19M 808 R 0 51.0 30.9 0:05 ecomsiz.exe 2030 matt 11 0 2424 2424 704 R 0 47.5 3.8 0:04 ecomsiz.exe Now, the 19M is about right, but the 2.4K is not even close to the right size. What is going on?? I am using mpich-1.1.1 on a RH Linux box under kernel 2.2.0. Please help me explain this THanks Matt
