Hi Starcluster
Do anyone have advice on what fabric to use when running on AWS?
I know the interconnect is supposed to be 10-gigE but my model is more dependent on latency than throughput.
I have had to use the Intel Cluster Compiler Suite rather than the built in OpenMPI. Hoping to resolve those issues and compare the two – I am interested to see the performance differences…
Currently the model actually has a negative performance curve as I add processors past a single node.
Model performance on running on Amazon…
