Pramod (who did the work) was my student at EPCC last year. We looked at porting Fluidity (or bits of it) to GPU and as a result decided that working on PETSc's GPU support was going to be the most promising angle for the time we had available. We have never got round to benchmarking Fluidity with Pramod's extended sparse matrix format support, but it shouldn't be too much effort.

If you have any questions about it all, feel free to ask.

Excellent. I will read over the report and mail questions. Thanks, Matt

Has anyone taken a look at this:

It is the Fluidity people I think. I have just gotten an NSF award with Dan Negrut in Wisconsin and Ahmed Sameh at Purdue to port Ahmed's SPIKE preconditioner (you may have heard Olaf Schenk talk about this) to PETSc, and in particular to PETSc's GPU backend so that Dan can run it on his GPU cluster. Thus, we will be seriously stressing this feature in the near future.
