# 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.

## Options Database Key

- -mat_type sellhip - sets the matrix type to `MATSELLHIP` during a call to MatSetFromOptions()
