We (Robin) found a solution to the reading the input file problem.
the flag "-local" needs to be used. I was able to run this code using
different number of cpus, 2,4,8,12. When I tried 16 I got an error
which I think is related to IB.

myid=    3 myid_row=    3 myid_col=    0
myid=    3 myrow=    1 mycol=    4    (  1 <= i <= 200) ,  (601 <= j <= 800)
myid=   12 myid_row=    0 myid_col=    3
myid=   12 myrow=    4 mycol=    1    (601 <= i <= 800) ,  (  1 <= j <= 200)

and the error file is:
