Hi guys,
I'm getting 'Segmentation fault (core dumped)' error when running (in the
very beginning):
./dmtcp_launch mycode
Tried both in Virtualbox linux (with master version from zip file) and in
interactive session on our cluster (i.e. no scheduler, just from terminal,
with 2.5.1 version) - same error. In both cases I didn't use mpirun that is
without MPI. Tried with mpirun also - same error.
Tried for test:
./dmtcp_launch ls
- works.
Is there a way to troubleshoot? Thinking of Valgrind, though not sure what
should be the order of valgrind and dmtp_launch in command line.
Thank you.
