Hello,
The --with-rpi option that you are using in the configure line is
for selecting a RPI module type. RPI is used for point to point MPI
message communication. crtcp is the tcp module that can be checkpointed an
restarted.
For checkpoint/Restart you have to have the BLCR module on your
machine. You can use the BLCR module if you configure LAM with
--with-blcr=PATH (PATH is the path where the BLCR module could be found)
--with-rpi=crtcp is needed as blcr module cannot run without it.
However, it configuration of blcr module fails then it will be
skipped at compile time and hence wont be available at run time.

- The "blcr" module requested in the CR kind was not found.
- This typically means that you misspelled the desired module name, or
- used
- the wrong name entirely.

- The crmpi SSI subsystem failed to open during MPI_INIT. This is a

- This occurred on host can33.kaist.ac.kr (n0).
- The PID of failed process was 15898 (MPI_COMM_WORLD rank: 0)

- It seems that [at least] one of the processes that was started with
- mpirun did not invoke MPI_INIT before quitting (it is possible that
- more than one process did not invoke MPI_INIT -- mpirun was only
- notified of the first one, which was on node n0).
- mpirun can *only* be used with MPI programs (i.e., programs that
- invoke MPI_INIT and MPI_FINALIZE). You can use the "lamexec" program
- to run non-MPI programs over the lambooted nodes.

- How can I use blcr module? Please help. Thank you.
