Intel® MPI Library

Using Checkpoint-Restart

The checkpoint-restart feature is available with the Hydra process launcher (mpiexec.hydra) or its wrapper (mpirun). The launcher provides two mutually exclusive methods of taking checkpoints:

  • By timers

  • By an explicit signal

You can provide directory paths where checkpoints can be stored temporarily and permanently.

ILP64 Support

The term ILP64 means that integer, long, and pointer data entities all occupy 8 bytes. This differs from the more conventional LP64 model in which only long and pointer data entities occupy 8 bytes while integer entities occupy 4 bytes. More information on the historical background and the programming model philosophy can be found, for example, in http://www.unix.org/version2/whatsnew/lp64_wp.html
