public MemoryGrp {
int size(int node)
Returns the amount of memory residing on node.
Definition memory.h:165
distsize_t offset(int node)
Returns the global offset to node's memory.
Definition memory.h:168
void * localdata()
Returns a pointer to the local data.
void set_localsize(size_t)
Set the size of locally held memory.
void sync()
Synchronizes all the nodes.
void * obtain_readonly(distsize_t offset, int size)
This gives read access to the memory location. No locking is done.
void * obtain_readwrite(distsize_t offset, int size)
Only one thread can have an unreleased obtain_readwrite at a time.
void release_readonly(void *data, distsize_t offset, int size)
This is called when read access is no longer needed.
void release_readwrite(void *data, distsize_t offset, int size)
This is called when read/write access is no longer needed.
void release_writeonly(void *data, distsize_t offset, int size)
This is called when write access is no longer needed.
void * obtain_writeonly(distsize_t offset, int size)
This gives write access to the memory location. No locking is done.
A template class that maintains references counts.
