http://pubs.acs.org/doi/abs/10.1021/ct100439u is the paper I was implicitly referencing. They do RAID inside of GA. I can only do this sanely with MPI RMA (ie without resorting to nproc times as many windows as necessary) if and only iff I can continue to use data after process failure if I know it could not have been corrupted. It is possible that the paper doesn't adequately explain things for this context, in which case I will provide them later. Other stuff that may or may matter: http://hpc.pnl.gov/people/vishnu/public/vishnu_overdecomposition.pdf http://hpc.pnl.gov/people/vishnu/public/vishnu_hipc10.pdf http://dx.doi.org/10.1109/PDP.2011.72 http://link.springer.com/chapter/10.1007/978-3-642-23397-5_34 I assume someone from Argonne has presented GVR to the WG?

Jeff,

I was trying to find some references to the GA FT work you mentioned during the plenary discussion today.

The only reference I could find about the FT capabilities of GA is [1] but it is getting dusty. A more recent reference [2] addresses NWCHEM in particular, but represents an application-specific user-level checkpoint/restart strategy, requiring minimal support from the communication library and that has little in common with the ongoing discussion in the WG.

I would really appreciate if you could provide a reference.

Thanks, George.

I'm also attaching the slides to this email and I believe they'll be posted on the forum website by Martin at some point.

Thanks, Wesley
