Hi --
Some more pointers --
- The output of "laminfo" will give you complete list of the modules that
have been installed. This will help you to track whether cr with blcr
module was built or not.
- For the cr_restart command, the argument is a context file (context.pid)
and not "pid".

#
# The configure switch to enable crtcp as default is --with-rpi=crtcp (NOTE

#
# For blcr to work, atleast "gm" or "crtcp" rpi should be set as default. In
# your case, --with-rpi-crtcp did not work, and hence blcr module was not
# configured (as you saw in the error message you got while using -ssi cr
# blcr). You can check the output of config.log to confirm this.
#
# I think this lead to all other problems you got after that.
#
# If your problem persists, send across the config.log, which can help
# pinpoint the problem.

# Hope this helps...

# # Now when I do check point of ordinary processes using blcr it works fine. I

# # mpirun -ssi rpi crtcp -ssi cr blcr -np 4 ./ring
# # This produces error stating blcr module in CR kind was not found. This

# #
# # So I ran the program with command
# # mpirun -ssi rpi crtcp -np 4 ./ring
# # and it works fine. Now I checkpoint with the command
# # cr_checkpoint 23245 where 23245 is PID of mpirun. One file named
# # context.23245 is created and no other files are created (Should other files
# # be created). This file is created on node where I run command cr_checkpoint.
# # (Note I don't have NFS on my test cluster)
# #
# # When I try to restart the original program from context file with command
# # cr_restart 23245 I get the error
# # mpirun (rpwait) : bad file descriptor. (Note: The original process has
# # already completed execution)
# #
# # Please let me know if these errors are due to some lapse in installation or
