Detailed Description

Defines prototypes of methods on MemoryRegister.

MemoryRegister is a table containing memory locations of variables on all processors. Memory locations on the same row are bsp_push_reg()'ed on all processors at the same time (at the same position in the code)

Function Documentation

void memoryRegister_destruct (  ExpandableTable *  restrict  ) 
 

void memoryRegister_expand (  ExpandableTable *  restrict,
const   int
) 
 

static MemRegElement memoryRegister_find (  const ExpandableTable *restrict  table,
const int  sp,
const int  dp,
const char *const   pointer
)  [inline, static]
 

looks up a the address on a remote processor which corresponds to an address on the local processor

Parameters:
table Reference to a MemoryRegister
sp Rank of the local processor
dp Rank of the remote processort
pointer Local address of a registered memory location
Returns:
Remote address

Here is the call graph for this function:

void memoryRegister_initialize (  ExpandableTable *  restrict,
const   int,
const   int,
const   int
) 
 

static MemRegElement memoryRegister_memoized_find (  const ExpandableTable *restrict  table,
const int  dp,
const char *const   pointer
)  [inline, static]
 

looks up the address on a remote processor which corresponds to an address on the local processor.

This function is memoized and depends on the MemoryRegisters state of being 'packed'. If not, this function will not function properly

Parameters:
table Reference to a MemoryRegister
dp Rank of the remote processor
pointer Local address of a registered memory location
Returns:
Remote address
