cuSOLVERMp Data Types

Data types

cusolverMpHandle_t

The cusolverMpHandle_t structure holds the cuSOLVERMp library context (device properties, system information, etc.).

The handle must be initialized and destroyed using cusolverMpCreate() and cusolverMpDestroy() functions respectively.

cusolverMpGrid_t

The cusolverMpGrid_t structure holds information about the grid dimensions and stores the communicator associated to the grid of processes.

It must be initialized and destroyed using cusolverMpCreateDeviceGrid() and cusolverMpDestroyGrid() functions respectively.

cusolverMpMatrixDescriptor_t

The cusolverMpMatrixDescriptor_t structure captures the shape and characteristics of a distributed matrix.

It must be initialized and destroyed using cusolverMpCreateMatrixDesc() and cusolverMpDestroyMatrixDesc() functions respectively.

Enumerators

cusolverMpGridMapping_t

Describes the ordering of the grid of processes.

Value	Meaning
CUSOLVERMP_GRID_MAPPING_ROW_MAJOR	The grid of processes will be accessed in row-major ordering.
CUSOLVERMP_GRID_MAPPING_COL_MAJOR	The grid of processes will be accessed in column-major ordering.

cusolverMpLoggerCallback_t

Function pointer type for cuSOLVERMp logging callbacks. The callback function is called by the library to report logging information.

The callback can be set using cusolverMpLoggerSetCallback().

The callback function takes the following parameters:

Parameter	Type	Description
logLevel	int	The severity level of the log message.
functionName	const char*	Name of the function generating the log message.
message	const char*	The actual log message text.
