ROCSHMEM_MALLOC
|
|
---------------
|
|
|
|
.. cpp:function:: __host__ void *rocshmem_malloc(size_t size)
|
|
|
|
:param size: Memory allocation size in bytes.
|
|
:returns: A pointer to the allocated memory on the symmetric heap.
|
|
If a valid allocation cannot be made, it returns ``NULL``.
|
|
|
|
**Description:**
|
|
This routine allocates memory of ``size`` bytes from the symmetric heap.
|
|
This is a collective operation and must be called by all PEs.

ROCSHMEM_FREE
|
|
-------------
|
|
|
|
.. cpp:function:: __host__ void rocshmem_free(void *ptr)
|
|
|
|
:param ptr: A pointer to previously allocated memory on the symmetric heap.
|
|
:returns: None.
|
|
|
|
**Description:**
|

This routine frees a memory allocation from the symmetric heap.
|
|
It is a collective operation and must be called by all PEs.
