MATSELLHIP#

“sellhip” = “mpisellhip” - A matrix type to be used for sparse matrices on AMD GPUs Sliced ELLPACK matrix type whose data resides on GPUs.

This matrix type is identical to MATSEQSELLHIP when constructed with a single process communicator, and MATMPISELLHIP 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.
