Hello @ll<div><br></div><div>I&#39;ve got a problem when i try to use the ompi-migrate command.  </div><div><br></div><div>What i&#39;m doing is execute for example the next application in one node of a cluster (both process wil run on the same node):</div>
<div><br></div><div><i>mpirun -np 2 -am ft-enable-cr ./whoami 10 10</i></div><div><br></div><div>Then in the same node i try to migrate the processes to another node:</div><div><br></div><div><i>ompi-migrate -x node9 -t node3 14914</i></div>
<div><i><br></i></div><div>And then i get this message:</div><div><br></div><div><div><i>[clus9:15620] *** Process received signal ***</i></div><div><i>[clus9:15620] Signal: Segmentation fault (11)</i></div><div><i>[clus9:15620] Signal code: Address not mapped (1)</i></div>
<div><i>[clus9:15620] Failing at address: (nil)</i></div><div><i>[clus9:15620] [ 0] /lib64/libpthread.so.0 [0x2aaaac0b8d40]</i></div><div><i>[clus9:15620] *** End of error message ***</i></div><div><i>Segmentation fault</i></div>
</div><div><i><br></i></div><div>I assume that maybe there is something wrong with the thread level, but i have configured the open-mpi like this:</div><div><br></div><div><i>../configure --prefix=/home/hmeyer/desarrollo/ompi-code/binarios/ --enable-debug --enable-debug-symbols --enable-trace --with-ft=cr --disable-ipv6 --enable-opal-multi-threads --enable-ft-thread --without-hwloc --disable-vt --with-blcr=/soft/blcr-0.8.2/ --with-blcr-libdir=/soft/blcr-0.8.2/lib/</i></div>
<div><i><br></i></div><div>The checkpoint and restart works fine, but when i restore an application that has more than one process, this one is restored and executed until the last line before MPI_FINALIZE(), but the processes never finalize, i assume that they never call the MPI_FINALIZE(), but with one process ompi-checkpoint and ompi-restart work great.</div>
