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.

Options Database Key

• -mat_type mpisellcuda - sets the matrix type to MATMPISELLCUDA during a call to MatSetFromOptions()
