DESCINIT parameter number 9 had an illegal value

I can execute the scalapack example of netlib. http://www.netlib.org/scalapack/examples/sample_pzheevx_call.f

However, when I use N = 600 instead of N = 4, some messages are printed:

{ 0, 0}: On entry to
DESCINIT parameter number 9 had an illegal value
{ 0, 0}: On entry to
DESC{ 0, 1}: On entry to

I compile this example using intel mpi and intel mkl 2016 version.

mpiifort -O1 -o example1 sample_pssyevx_call.f -lmkl_scalapack_lp64 -lmkl_blacs_intelmpi_lp64 -lmkl_lapack95_lp64 -lmpi -lmkl_sequential -lmkl_intel_lp64 -lmkl_core -lpthread -lm -ldl

You used a value of N (600) that is larger than the integer parameter MAXN (100) that is used in the example code to allocate some of the arrays. Did you remember to adjust MAXN accordingly?

Thank you so much! I changed the MAXN and the problem is solved.
