ScaLAPACK Example Program #1 -- May 1, 1997
 
Solving Ax=b where A is a   9 by   9 matrix with a block size of   2
Running on   6 processes, where the process grid is   2 by   3
 
INFO code returned by PDGESV =   0
 
According to the normalized residual the solution is correct.
 
||A*x - b|| / ( ||x||*||A||*eps*N ) =   0.00000000E+00
