I'm afraid this doesn't make much sense to me. LSF has dispatched node1 and
node2 - correct? It sounds like you have also given those names aliases that
refer to their IB ports - generally a very bad practice, but let's set that
aside for now.
If they are the same physical nodes, then the node
Can you help me?
The bnode1.bnode2
and node1,node2 are the hostnames of the same nodes corresponding
to the InfiniBand and ethernet network respectively.
The node1,node2 are the nodes declarated in lsf.cluster.name
In order to use the IB network, I
I am using Open-MPI in a parallelization of matrix multiplication for large
matrices.
My question is:
- Is MPI_File_read using mmapping under the hood when reading a binary
file.
- Or is the better/most efficient solution to read the input files using
the native mmap in C++
