ABSTRACT:
A method of operating a data processing system includes each of multiple tasks within a parallel job executing on multiple nodes of the data processing system issuing a system call to request allocation of backing storage in physical memory for global shared memory accessible to all of the multiple tasks within the parallel job, where the global shared memory is in a global address space defined by a range of effective addresses. Each task among the multiple tasks receives an indication that the allocation requested by the system call was successful only if the global address space for that task was previously reserved and backing storage for the global shared memory has not already been allocated.
