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 unsigned  int )

static MemRegElement memoryRegister_find (  const ExpandableTable *restrict  table, const unsigned int  sp, const unsigned 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 Definition at line 65 of file bsp_memreg.h. References bsp_intern_abort(), ERR_POP_REG_WITHOUT_PUSH, and restrict. Here is the call graph for this function:

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

static MemRegElement memoryRegister_memoized_find (  const ExpandableTable *restrict  table, const unsigned 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 Definition at line 93 of file bsp_memreg.h. References restrict. Referenced by bsp_get(), and bsp_put().

void memoryRegister_pack (  ExpandableTable *  restrict  )

void memoryRegister_pop (  ExpandableTable *  restrict, const unsigned  int, const char *const   restrict )

void memoryRegister_push (  ExpandableTable *  restrict, const unsigned  int, const char *const   restrict )
