Hi,
from what you describe below, seems as if you did not configure well
OpenMPI.
You issued
./configure --with-ft=cr --enable-mpi-threads --with-blcr=/usr/local/bin
--with-blcr-libdir=/usr/local/lib
while according to the installation paths you gave it should have been
more like
./configure --with-ft=cr --enable-mpi-threads --with-blcr=/root/MS
--with-blcr-libdir=/root/MS/lib
Apart from that, if you wish to have BLCR modules loaded at start up of
your machine, a simple way is to add the following lines in rc.local
This file is somewhere in /etc: the exact location can vary from one linux
distribution to another (e.g.: /etc/rc.d/rc.local or /etc/rc.local)
/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
Just in case, if you have multiple MPIs installed, you can check which
you are using with the following command:
which mpirun

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@localhost examples]# mpicc -o res arr_add.c
[root@localhost examples]# mpirun -np 2 -am ft-enable-cr ./res
2 2 2 2 2 2 2 2 2 2

Error: The process with PID 5790 is not checkpointable.
This could be due to one of the following:
- An application with this PID doesn't currently exist
- The application with this PID isn't checkpointable
- The application with this PID isn't an OPAL application.
We were looking for the named files:
/tmp/opal_cr_prog_write.5790
/tmp/opal_cr_prog_read.5790

NOTE: the PID of mpirun is 5788
i geve the following command for taking the checkpoint
[root@localhost examples]#ompi-checkpoint -s 5788
i got the following output , but it was hanging like this
[localhost.localdomain:05796] Requested - Global Snapshot
Reference: (null)
[localhost.localdomain:05796] Pending - Global Snapshot
Reference: (null)
[localhost.localdomain:05796] Running - Global Snapshot
Reference: (null)
can anybody resolve this problem
kindly rectify it.
with regards
