Hello ! I had some problems . My environment BLCR= 0.8.4 , openMPI= 1.5.5 , OS= ubuntu 11.04 I have 2 Node : cuda05(Master ,it have NFS file system) , cuda07(slave ,mount Master)
I had also set ~/.openmpi/mca-params.conf-> crs_base_snapshot_dir=/root/kidd_openMPI/Tmp snapc_base_global_snapshot_dir=/root/kidd_openMPI/checkpoints my configure format=./configure --prefix=/root/kidd_openMPI --with-ft=cr --enable-ft-thread --with-blcr=/usr/local/BLCR --with-blcr-libdir=/usr/local/BLCR/lib --enable-mpirun-prefix-by-default --enable-static --enable-shared --enable-opal-multi-threads; problem 1: ompi-restart on multiple Node command 01: mpirun -hostfile Hosts -am ft-enable-cr -x LD_LIBRARY_PATH -np 2 ./TEST command 02: ompi-restart ompi_global_snapshot_2892.ckpt -> I can checkpoint 2 process on multiples nodes ,but when I restart ,it can only restart on Master-Node. command 03 : ompi-restart -hostfile Hosts ompi_global_snapshot_2892.ckpt ->Error Message .
