Hello,
When I execute lapw1_mpi, it dies on me immediately:
$ ./lapw1_mpi
w2k_dispatch_signal(): received: Segmentation fault
Child id 0 SIGSEGV, contact developers
--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 6.
NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
--------------------------------------------------------------------------
It turns out that the offending line is the first call to SL_INIT in
INIT_PARALLEL (SRC_lapw1/modules.F),
SUBROUTINE INIT_PARALLEL
IMPLICIT NONE
#ifdef Parallel
include 'mpif.h'
INTEGER :: IERR,i,j
call MPI_INIT(IERR)
call MPI_COMM_SIZE( MPI_COMM_WORLD, NPE, IERR)
call MPI_COMM_RANK( MPI_COMM_WORLD, MYID, IERR)
CALL BARRIER
-> CALL SL_INIT(ICTXTALL, 1, NPE)
which is called eventually via GTFNAM at the top of the main program
LAPW1.
I used ifort version 11.1 (specifically, I tried two revisions: 046
and 072) and the corresponding MKL libraries (including ScaLAPACK).
The MPI version is openmpi-1.3.2-icc, in case that matters. Neither
lapw0_mpi nor lapw2_mpi have this problem (then again, they do not
seem to use SL_INIT).
Any pointers how I should proceed?
Thanks,
Elias
