When I try to run an application (just a simple hello_world.c doesn't work) I receive this error every time:
mpiexec -ckpointlib blcr -ckpoint-prefix /tmp/ -ckpoint-interval 10 -machinefile /tmp/machinefile -n 1 ./app_name [proxy:0:0@masterpi] requesting checkpoint [proxy:0:0@masterpi] checkpoint completed [proxy:0:0@masterpi] requesting checkpoint [proxy:0:0@masterpi] HYDT_ckpoint_checkpoint (./tools/ckpoint/ckpoint.c:111): Previous checkpoint has not completed.[proxy:0:0@masterpi] HYD_pmcd_pmip_control_cmd_cb (./pm/pmiserv/pmip_cb.c:905): checkpoint suspend failed [proxy:0:0@masterpi] HYDT_dmxu_poll_wait_for_event (./tools/demux/demux_poll.c:77): callback returned error status [proxy:0:0@masterpi] main (./pm/pmiserv/pmip.c:206): demux engine error waiting for event [mpiexec@masterpi] control_cb (./pm/pmiserv/pmiserv_cb.c:202): assert (!closed) failed [mpiexec@masterpi] HYDT_dmxu_poll_wait_for_event (./tools/demux/demux_poll.c:77): callback returned error status [mpiexec@masterpi] HYD_pmci_wait_for_completion (./pm/pmiserv/pmiserv_pmci.c:197): error waiting for event [mpiexec@masterpi] main (./ui/mpich/mpiexec.c:331): process manager error waiting for completion I want just to make a checkpoint and nothing else (and restart later).
Thanks in advance
UPDATE:
I have tried with MPICH2, no chance. Or maybe I'm wrong somewhere...

If someone has a working example (irrelevant what it makes, simple working "Hello World" would make me happy!) I would be very glad.
Happy new year!
