Do you expect either of HYPRE_IJMatrixSetRowSizes or HYPRE_IJMatrixSegDiagOffdSizes to make a difference for GPU assembly? -Paul From: Ruipeng Li Reply-To: hypre-space/hypre Date: Wednesday, December 2, 2020 at 11:13 PM To:...

I’m gonna take a crack at this. I’ve been reading the assembly code in IJMatrix_parcsr_device.c and I have a pretty good idea of what’s happening. I’m going to create a...

I have a working version of this code in a fork/branch. It's pretty much up to date with Hypre master. I would read my SC 21 paper to get details...

It's not clear to me where the issue resides. These warnings are very similar to what I saw in #929 and subsequently fixed in #942. I agree that this may...

I found more examples of problems in a parallel reduce. This one occurs for a RelWithDebInfo build (gcc 10.2, cuda 11.4.2) at: https://github.com/Exawind/nalu-wind/blob/master/src/HypreUVWLinearSystem.C#L527 Notice that in each case, the read/write...

Yes

I'll fix. Sorry

This may be my fault. I think I need to update trilinos though I'm worried new trilinos won't build with GPU on summit. I was using an old trilinos from...

Ok. I saw that also. That's why I didn't update Trilinos. I can push a fix but I won't know if things build/run correctly until Trilinos gets fixed.
