Hi, 

I would like to make example program cpi.c to be able to run wih one or
more arguments, for example:

mpiexec cpi.exe 1000

where 1000 is, say, number of rectangles.

I saw that MPI_Init(&argc,&arv) uses argumets passed to main method, but
not more than that..

how can I acheve passing number of rectangles to cpi.exe?

I attached original version of cpi.c

Sole
