void sync()
Synchronizes all the nodes.
void print(std::ostream &o=ExEnv::out0()) const

void * malloc_local(size_t nbyte)
Allocate data that will be accessed locally only.
void deactivate()
Deactivate is called after the memory has been used.
static std::ostream & out0()
Return an ostream that writes from node 0.
distsize_t offset(int node)
Returns the global offset to node's memory.
