dear sir
i am sending the details as follows
1. i am using openmpi-1.3.3 and blcr 0.8.2
2. i have installed blcr 0.8.2 first under /root/MS
3. then i installed openmpi 1.3.3 under /root/MS
4 i have configured and installed open mpi as follows
#./configure --with-ft=cr --enable-mpi-threads
--with-blcr=/usr/local/bin
--with-blcr-libdir=/usr/local/lib
# make
# make install
then i added the following to the .bash_profile under home
directory( i went to home directory by doing cd ~)
/sbin/insmod
/usr/local/lib/blcr/2.6.23.1-42.fc8/blcr_imports.ko
/sbin/insmod /usr/local/lib/blcr/2.6.23.1-42.fc8/blcr.ko
PATH=$PATH:/usr/local/bin
MANPATH=$MANPATH:/usr/local/man
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
then i compiled and run the file arr_add.c as follows
[root_at_localhost examples]# mpicc -o res arr_add.c
[root_at_localhost examples]# mpirun -np 2 -am ft-enable-cr
./res

NOTE: the PID of mpirun is 5788
i geve the following command for taking the checkpoint
[root_at_localhost examples]#ompi-checkpoint -s 5788
i got the following output , but it was hanging like this
[localhost.localdomain:05796]
