`cusolverMpCreate`¶

cusolverStatus_t cusolverMpCreate(
        cusolverMpHandle_t *handle,
        int device,
        cudaStream_t stream)

The function initializes the cuSOLVERMp library handle (cusolverMpHandle_t) which holds the cuSOLVERMp library context. It allocates light hardware resources on the host, and must be called prior to making any other cuSOLVERMp library calls.

The cuSOLVERMp library context is tied to the CUDA device provided by device and the CUDA stream stream.
Only one handle per process and per GPU supported. Sharing a device with multiple processes will result in undefined behavior.

Parameter	Memory	In/Out	Description

Computes the Cholesky factorization of an N-by-N real symmetric or a complex hermitian positive definite distributed matrix sub(A) denoting A(IA:IA+N-1, JA:JA+N-1).

If A is upper triangular and uplo=CUBLAS_FILL_MODE_UPPER, the factorization has the form

$sub(A) = U^H \cdot U$

where U is upper triangular.

If the matrix is lower triangular and uplo is set to CUBLAS_FILL_MODE_LOWER, the factorization has the form

$sub(A) = L \cdot L^H$

where L is lower triangular.

The user can combine cusolverMpPotrf() and cusolverMpPotrs() to solve a system of linear equations.

Multiply distributed M-by-N matrix sub(C) denoting C(IC:IC+M-1, JC:JC+N-1) by the orthogonal matrix Q can be given from cusolverMpGeqrf().
