[mpich-discuss] Problem during running a parallel processing.

[Sinta Kartika Maharani]

I'm using the debugger in visual c++. The error was "Unhandled
exception at 0x00f0157e in lastproject.exe: 0x0000094 : integer
division by zero" the code is attached.
The error is in "averow = NRA/numworkers;" whereas I declare the
number of processor when running it with mpiexec.
