I can't go into specifics. with HPL i usually can't top 80-85% of full power draw per cabinet. we have cabinets ranging from 17kw, 25kw, and 35kw. some of our user codes can push the machines to 90% of full load. this is shown on both amd 4-socket nodes and intel dual-socket with gpu's. we're running 208v three phase to the racks and 208v single phase to each server
