MATSELLCUDA#
“sellcuda” = “mpisellcuda” - A matrix type to be used for sparse matrices. Sliced ELLPACK matrix type whose data resides on NVIDIA GPUs.
This matrix type is identical to MATSEQSELLCUDA when constructed with a single process communicator,
and MATMPISELLCUDA otherwise. As a result, for single process communicators,
MatSeqSELLSetPreallocation() is supported, and similarly MatMPISELLSetPreallocation() is supported
for communicators controlling multiple processes. It is recommended that you call both of
the above preallocation routines for simplicity.
