i raised it to 20 sec but same results sorry i am new to checkpoint restart i am trying this initially on one multicore pc how should it look like if the restart succeed? should it work in the same terminal in which i am running restart command my test app has 5000 iterations , checkpoint is taken at iteration no 300 for example , if i choose to restart from this checkpoint file should it restart near this iteration no 300 2013/6/6 Wesley Bland <[email protected]>

Is there actually anything in those checkpoints? With a checkpoint happening every 4 seconds you may be overdoing it.

i used mpiexec with checkpoint and created two checkpoint files:

mpiexec -ckpointlib blcr -ckpoint-prefix /home/john/ckpts/app.ckpoint

-ckpoint-interval 4 -n 4 /home/john/app/md

...

context-num0-0-0 context-num1-0-0

i am trying to make a restart mpiexec -ckpointlib blcr -ckpoint-prefix /home/john/ckpts/app.ckpoint

-n 4 -ckpoint-num 1

...

but nothing happened it just hangs i also tried: mpiexec -ckpointlib blcr -ckpoint-prefix /home/john/ckpts/app.ckpoint

-n 4 -ckpoint-num 0-0-0

...

also hangs
