The information below applies to the Test and Development System (TDS) which is similar to the future Hawk production system. Please have in mind that this is a system under construction. Hence modifications might occur ''without'' announcement and stuff may not work as expected from time to time!

'''Tuned MPI''': In order to use the MPI implementation provided by HPE, please load the Message Passing Toolkit (MPT) module ''mpt'' (not ABI-compatible to other MPI implementations) or ''hmpt'' (ABI-compatible to MPICH-derivatives).


'''User Guide''': For detailed information cf. the [http://www.hpe.com/support/mpi-ug-036 HPE Message Passing Interface (MPI) User Guide].

'''Performance optimization''': With respect to MPI performance optimization by means of tuning environment variables please cf.

'''Interconnect topology''': Hawk deploys an Infiniband HDR based interconnect with a 9-dimensional enhanced hypercube topology. Please refer to [https://kb.hlrs.de/platforms/upload/Interconnect_topology.pdf here] with respect to the latter. Infiniband HDR has a bandwidth of 200 Gbit/s and a MPI latency of ~1.3us per link. The full bandwidth of 200 Gbit/s can be used if communicating between the 16 nodes connected to the same node of the hypercube (cf. [https://kb.hlrs.de/platforms/upload/Interconnect_topology.pdf here]). Within the hypercube, the higher the dimension, the less bandwidth is available.
