Title Accessing shared memory on different nodes
Ref. No. QNX.000009814
Category(ies) Network, Development
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.
