Function Documentation

magma_int_t magma_init

(

void

)

Initializes the MAGMA library.

Caches information about available CUDA devices.

Every magma_init call must be paired with a magma_finalize call. Only one thread needs to call magma_init and magma_finalize, but every thread may call it. If n threads call magma_init, the n-th call to magma_finalize will release resources.

When renumbering CUDA devices, call cudaSetValidDevices before calling magma_init. When setting CUDA device flags, call cudaSetDeviceFlags before calling magma_init.

Return values

MAGMA_SUCCESS
MAGMA_ERR_UNKNOWN
MAGMA_ERR_HOST_ALLOC
