It looks like your blcr installation is not functioning correctly. Did you try it outside of the mpich environment to make sure it's installed correctly? -- Pavan On 09/21/2012 05:03 AM US Central Time, Manisha Chauhan wrote:

Hi all

I mailed you earlier also but didnot get reply for my query. Hoping to get this time. I installed BLCR tool with MPICH2 and HYDRA module.

While checkpointing an MPI application i have given this command-

mpirun -ckpointlib blcr -ckpoint-prefix /home/superusr/bhavya/b_eff_io/tmp/app.ckpoint -ckpoint-interval 10 -np 4 ./beff_out1 -MB 2730 -MT 32768 -T 20 -p ../test -f ../test_out/ser11_9_2012_20sec3
