Hello,
I have successfully installed a Cluster running with HPC Pack 2016 U2. The compute nodes are Windows 2012 R2 servers and the head node are a Windows 2016 server. Infiniband is used as application network. For this, every server has a Mellanox ConnectX-3
Infiniband Adapter with newest firmware and driver. At network device advanced settings, RDMA is enabled.
The problem is, in the HPC Cluster Manager Resource Management, the head node is the only one which the "Network Direct" option is true.
This means, for my understanding, that RDMA only works on the head node.
Can anyone help me to find out what is configured wrong on the compute nodes, why network direct is shown as false?
Are there some options to configure RDMA in MS HPC Pack 2016?
Thanks
Andi
