Fernando,

Thank you for your reply.
I tried to patch the file you mentioned, but the output did not change.

>Are you using a shared file system? You need to use a shared file
system for checkpointing with 1.4.1:
What is the shared file system ? do you mean NFS, Lustre and so on ?
(I'm sorry about my ignorance...)

If I use only one node for application, do I need such a shared-file-system ?
