[Wien] Problems with lapw1_mpi in 64-bit

[Peter Blaha]

Hi,

I run lapw1_mpi in 64bit Xeon machines without problems.

Have you tried a "smaller problem" ? Could be a memory problem.

mpi seems to work (as also your test say, or try lapw0_mpi), but
maybe there is a problem with SCALAPACK/BLACS. Where does your
SCALAPCK  come from ??
 
Regards
