What Ralf was trying to point out is that you used /home/buntinas in a path. That home directory was likely cut-and-paste from an example created by Darius Buntinas, a developer of MPICH. It is almost certainly not a valid path on your machine. Your home directory appears to be /home/basma/, which makes sense given your name. When Ralf said "It sounds like that path should be something like /home/basma/ckpts/app.ckpoint instead," he was not suggesting that you blindly cut-and-paste that path and assume it would work. The use of "something like" was meant to provoke some analysis on your part that would lead to you identify the appropriate path to use there. I am tempted to suggest that you use "-ckpoint-prefix /dev/null", which will probably work (just not the way you might like), but I am afraid that you will not internalize what I'm trying to say and actually follow that advice.

Thank you for your help
i am using mpich-3.0.3 . with blcr-0.8.5 to checkpoint the integer Sort App of NPB, it give me the following error :
basma@basma-Satellite-A500:~$ mpiexec -ckpointlib blcr -ckpoint-prefix /home/buntinas/ckpts/app.ckpoint -ckpoint-interval 1 -n 4 /home/basma/NPB3.3/NPB3.3/NPB3.3-MPI/bin/is.A.4
It sounds like that path should be something like /home/basma/ckpts/app.ckpoint instead.
