| Issue |
Can shared memory be used between processes running on different nodes?
|
| Solution |
No. However, it would be fairly simple to use the sample code for shared memory queues (shmem & sem) and write a "manager" that receives requests from processes on other nodes. With a small cover function, it's possible to completely hide the multi-node nature and use IPC for remote queues and shmem for local. |
