Dear all
When i run parallel (With MPICH) version with 4 core, in output file i see
this "total time until now 6.06 sec." but if i use my watch it take 29 sec
to run. What is the problem?
another problem:
If i use MPICH with 1 core it takes only 17 sec (on my watch) which is
smaller than 29, Why?

Sincerely yours,

Mohsen Modaresi
