Distributed memory, MPI based SuperLU
I am using SuperLU to compute and apply an ILU-based preconditioner. I compute the factors (and solve the system) using `zgsisx`. Since SuperLU does not have GPU support, I am...
When i run audikw_1.mtx on superlu_dist with 32 rank, i get an assert : pdgstrf: Assertion `nbrow*(st_col+num_col_stream) < buffer_size' failed. what is this mean ang how can i fix it
I am running into problems on an M1 Mac with OpenMP builds and `OMP_NUM_THREADS` > 1. The error I receive is ``` ** On entry to DGEMM parameter number 8...
Here is my cmake command for PowerShell: ``` cmake ` -DTPL_BLAS_LIBRARIES="C:/OpenBLAS/lib/libopenblas.dll.a" ` -DCMAKE_BUILD_TYPE:STRING=Release ` -DCMAKE_COLOR_MAKEFILE:BOOL=FALSE ` -DCMAKE_VERBOSE_MAKEFILE:BOOL=TRUE ` -DCMAKE_C_COMPILER:FILEPATH="C:/Program Files (x86)/Microsoft Visual Studio/2022/BuildTools/VC/Tools/MSVC/14.38.33130/bin/Hostx64/x64/cl.exe" ` -DCMAKE_CUDA_COMPILER="C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v12.3/bin/nvcc.exe" `...
Dear Sherry Li, I'm shopping for a direct solver for one or several Poisson equations, which can be used in a single MPI process or in parallel. These need to...
I ran into an issue using the `METIS_AT_PLUS_A` reordering that the computed column permutation was different on different MPI processes, causing issues down the line in the symbolic factorization. This...
Hi Sherry, I found this issue while testing a combination of reusing the row and column permutations (SamePattern_SameRowPerm) and using parallel symbolic factorisation. This would fail with the assertion: `ERROR:...
I believe this is correct, I haven't run it though. This should fix the issue we faced with `xtrue` being different when the number of ranks are > 1.
