shmem_malloc_with_hints is added in OpenSHMEM 1.5, with hints SHMEM_MALLOC_ATOMICS_REMOTE|SHMEM_MALLOC_SIGNAL_REMOTE

Basic implementation

  • Reuse existing shmem_malloc

Optional optimizations

  • Develop equivalent hints for MPI_Win_allocate and use it to implement shmem_malloc_with_hints?
    • Potential drawback is the window lookup overhead at RMA/AMO operation
@minsii minsii added this to the FY21-Q3Q4 milestone Mar 3, 2021
@minsii minsii removed the optional label Mar 3, 2021
