shmem_ptr with OFI transport #164

Open kseager opened 8 years ago

kseager commented 8 years ago

Issue

shmem_ptr is currently not supported with OFI: enable supporting PE's that use the same node

(currently supported by Portals4 transport)

Solution Ideas

1) look into extending malloc heap setup to expose heap (require no-remote-va) 2) look into the capability exposure through OFI's shared memory implementation in the utility library

Current Solution

enabled XPMEM, including filing out internal on-node PE tracking array (USE_ON_NODE_COMMS)

Ideal solution

solution 1 (IPC) for portability purposes

@kseager, do you want to keep this one open?

kseager commented 8 years ago

sure we can let it hang for a bit, but label it enhancement since we have functionality with XPMEM now
