Hi,
you might want to rebuild Open MPI with the previous configure command
line, and append
--disable-dlopen CFLAGS='-g -O0'
by default, components are built into their own lib (for example
mca_btl_tcp.so) which is dlopen'ed and dlclose'd at runtime, and that might
not be supported by post mortem
Nick,
IMHO, the major issue here is the support for "static" data objects.
This requirement gets directly translated to the XPMEM support for the
platform, otherwise it is very challenging to get it implement.
OpenMPI/OSHMEM provides support for xpmem (actually there is more than
one transport), b
Hi all,
I am trying to perform memory allocation analysis in OpenMPI using valgrind and
use addr2line to get the location in the source code in the application and the
library.
I have compiled OpenMPI with valgrind using
./configure —prefix= —enable-debug —enable-mem-debug —enable-memchecker
