[Wien] dstart_mpi error

[Gavin Abo]

Good to hear that the "unable to get host address" and "unable to 
connect to server" errors are gone after you fixed the hosts file on 
each node.

Regarding the "no hfi units are available" error, if your system has 
Intel OP HFI cards, then maybe they just need configured to work [ 
https://software.intel.com/en-us/articles/using-intel-omni-path-architecture 
].  If your system does not have HFI cards, then maybe you need to set 
the I_MPI_FABRICS environmental variable on your system to use a 
different fabric like tcp [ 
https://software.intel.com/en-us/mpi-developer-guide-linux-selecting-fabrics 
].

I, however, am no expert on the Intel Parallel Studio Cluster Edition.

So, if the above doesn't help, another resource is:

Of the Intel Forums [ https://software.intel.com/en-us/forum ], the 
forum having the topic "Intel Clusters and HPC Technology" looks like it 
may be the most appropriate one to reach one of the Intel company's 
experts for the Intel Parallel Studio Cluster Edition.
