Detailed Description

API to handle data that can be allocated either in main or in GPU memory: for example, blocks of matrices in hybrid (CPU/GPU) matrix multiplication.

Enumeration Type Documentation

enum fupermod_mem_mode

Memory allocation modes, including C standard malloc and CUDA memory allocation. CUDA flags can be combined with "|"

Enumerator:

FUPERMOD_MEM_DEFAULT	C standard malloc
FUPERMOD_MEM_PAGELOCKED	Cuda memory allocation, allocate host memory as page-locked
FUPERMOD_MEM_PORTABLE	Cuda memory allocation, allocate host memory as page-locked by all CUDA contexts, not just the one that performed the allocation
FUPERMOD_MEM_MAPPED	Cuda memory allocation, maps the allocation into the CUDA address space
FUPERMOD_MEM_WRITECOMBINED	Cuda memory allocation, allocate host memory as write-combined, WC memory can be transferred quickly on PCI but cannot be read efficiently by most CPU

Function Documentation

void* fupermod_malloc	(	size_t	size,
		fupermod_process_conf *	conf
	)

Allocate a block of size bytes of memory. If NULL is returned, then there is something wrong

Parameters:

	size	size of memory to be allocated
	conf	process configuration

Returns:

a pointer to the beginning of the memory block

void fupermod_free	(	void *	ptr,
		fupermod_process_conf *	conf
	)

Free memory

Parameters:

	ptr	the beginning of the memory block to be freed
	conf	process configuration
