[mvapich-discuss] MVAPICH2-0.9.8 internal errors

[David Gunter]

I have recompiled mvapich2 without using the --enable-debuginfo flag  
and the problem has gone away.  However, I wish to have debuginfo  
available to our TotalView users so hopefully this can be resolved.

Here is the configuration that generates the error message I saw  
previously:

./configure --prefix=/opt/mvapich2/mvapich2-0.9.8-gcc/ib --with- 
openib=/usr/local/ofed --enable-romio --with-file-system=ufs+nfs 
+panfs --enable-sharedlibs=gcc --enable-debuginfo --enable-fast -- 
with-mpe

OFED is ofed-1.1

CFLAGS=-D_X86_64_ -D_SMP_ -DUSE_HEADER_CACHING  -DONE_SIDED - 
DMPID_USE_SEQUENCE_NUMBERS  -I/usr/local/ofed/include -O2   - 
D_SHMEM_COLL_

CC=/usr/bin/gcc
CXX=/usr/bin/g++
FC=/usr/bin/gfortran
F77=/usr/bin/gfortran
F90=/usr/bin/gfortran

The test was run on 32 process, 16 process, 8 process and 4 process -  
all of which generated this error message.

Thanks,
david
