Our new HP cluster has 25208 HCAs (Mellanox Arbel) but a new vendor-id... We have 0x1708 (presumably HP, hardware wise Cisco (Mellanox)) to add to the existing list in share/openmpi/mca-btl-openib-hca-params.ini that currently contains: # Mellanox 0x2c9 # Cisco 0x5ad # Silverstorm 0x66a # Voltaire 0x8f1
Somewhat related question 1: Is there a blessed way to map these ids back to strings? question 2: Is 1024 really the best MTU for DDR Arbel? I seem to remember this being 2048... /Peter
