i have successfully made LAPACK work. thanks to help from the people on
this list. now. i have also successfully compiled SCALAPACK with no
problems. however, when i ran the xdlutime program for benchmarking there
are no results? 

here is the output:
--------------
[wyy,/home/apps/libs/SCALAPACK/TESTING,02:15]$ mpirun N xdlutime 

Simple Timer for ScaLAPACK routine PDGESV
Number of processors used:   8

TIME     N  NB   P   Q  LU Time   Sol Time  MFLOP/S Residual  CHECK
---- ----- --- --- --- --------- --------- -------- -------- -------

Comments for the output:
Column 1: the time is the wall clock time
Column 2 & 3: matrix size (N by N) and block size (NB by NB)
Column 4 & 5: grid size (P by Q)
Column 6: total time (in seconds) to run PDGESV
Column 7: mega flops per seconds
Column 8: if PDGESV works fine

--------------

what could be wrong? pardon my ignorance.
