Macros
#define	magma_free(ptr)
	Frees GPU memory previously allocated by magma_malloc().

Functions
static magma_int_t	magma_imalloc (magmaInt_ptr *ptr_ptr, size_t n)
	Type-safe version of magma_malloc(), for magma_int_t arrays. Allocates n*sizeof(magma_int_t) bytes.
static magma_int_t	magma_index_malloc (magmaIndex_ptr *ptr_ptr, size_t n)
	Type-safe version of magma_malloc(), for magma_index_t arrays. Allocates n*sizeof(magma_index_t) bytes.
static magma_int_t	magma_uindex_malloc (magmaUIndex_ptr *ptr_ptr, size_t n)
	Type-safe version of magma_malloc(), for magma_uindex_t arrays. Allocates n*sizeof(magma_uindex_t) bytes.
static magma_int_t	magma_smalloc (magmaFloat_ptr *ptr_ptr, size_t n)
	Type-safe version of magma_malloc(), for float arrays. Allocates n*sizeof(float) bytes.
static magma_int_t	magma_dmalloc (magmaDouble_ptr *ptr_ptr, size_t n)
	Type-safe version of magma_malloc(), for double arrays. Allocates n*sizeof(double) bytes.
static magma_int_t	magma_cmalloc (magmaFloatComplex_ptr *ptr_ptr, size_t n)
	Type-safe version of magma_malloc(), for magmaFloatComplex arrays. Allocates n*sizeof(magmaFloatComplex) bytes.
static magma_int_t	magma_zmalloc (magmaDoubleComplex_ptr *ptr_ptr, size_t n)
	Type-safe version of magma_malloc(), for magmaDoubleComplex arrays. Allocates n*sizeof(magmaDoubleComplex) bytes.
magma_int_t	magma_malloc (magma_ptr *ptrPtr, size_t size)
	Allocates memory on the GPU.

Macro Definition Documentation

magma_free

magma_free

(

ptr

)

Frees GPU memory previously allocated by magma_malloc().

Parameters

[in]

ptr

Pointer to free.

Returns

MAGMA_SUCCESS

MAGMA_ERR_INVALID_PTR on failure

Function Documentation

magma_malloc()

magma_int_t magma_malloc	(	magma_ptr *	ptrPtr,
		size_t	size
	)

Allocates memory on the GPU.

CUDA imposes a synchronization. Use magma_free() to free this memory.

Parameters

[out]	ptrPtr	On output, set to the pointer that was allocated. NULL on failure.
[in]	size	Size in bytes to allocate. If size = 0, allocates some minimal size.

Returns

MAGMA_SUCCESS

MAGMA_ERR_DEVICE_ALLOC on failure

Type-safe versions avoid the need for a (void**) cast and explicit sizeof.
