Detailed Description

VE heterogeneous memory API functions.

Include "ve_offload.h" header from VH program. Specify -lveo when you link VH program. Include "veo_hmem.h" header from VH program. Specify -lveohmem when you link VE program.

Function Documentation

int veo_is_ve_addr ( const void * addr )

check the address

This function determines if the address is allocated by veo_alloc_hmem().

Parameters

[in] addr a pointer to virtual address

Return values

1	addr was allocated by veo_alloc_hmem().
0	addr was not allocated by veo_alloc_hmem().

void* veo_get_hmem_addr ( void * addr )

get a virtual address of VE or VH memory without identifier allocated by veo_alloc_hmem().

Parameters

[in] addr a pointer to virtual address of VE or VH memory

Returns: a virtual address without identifier

Examples:: examples/VE/libmpive.c.

int veo_get_max_proc_identifier ( void )

Get the number of identifiable VE processes.

Note: This API is a low-level API and is intended to be called by upper layer software. This API is not intended to be called by a user program.

Returns: the number of identifiable VE processes

int veo_get_proc_identifier_from_hmem ( const void * addr )

Get the number of VE process identifier from HMEM addr.

Note: This API is a low-level API and is intended to be called by upper layer software. This API is not intended to be called by a user program.

Parameters

[in] addr a pointer to VEMVA address with the identifier (HMEM addr)

Returns: a VE process identifer
