Re: [Scalablecr-discuss] Checkpointing using SCR

[Moody, A. T. <mo...@ll...>]

Hi Rommel,
Most of the applications using SCR contain logic to write their own checkpoints, so we don't have a lot of experience yet with third-party checkpointing packages.  Having said that, we know that the MVAPICH MPI team has integrated BLCR (Berkeley Lab Checkpoint Restart) with SCR.

Also, there is a research-level checkpointing package at LLNL which implements a persistent heap (variables stored in this region are checkpointed with a call to msync).  This package has also been integrated with SCR.

Is there a particular checkpointing package you have in mind?

Hi,
   You mention in your manuals that SCR is meant to work well with checkpointing packages that write a file per MPI process. Could you give some examples of the kind of checkpointing packages that will work well with SCR ?
