I started going to the Super Computer/HPC confs here in the USA over the last few years and it was shocking how few American companies are there with impressive hardware engineering. Maybe the Japanese/SKOrean/Taiwanese companies showing up are the Dell/IBMS of those countries and I'm just not familiar with the names but walking around the conference always gives me this feeling that the USA is lagging behind or sitting this one out. The majority of companies I see are the usual hardware conf goers; IBM/HP and then a bunch of Gov/NSA/DOD groups on the USA end with a few universities. On the AIPAC end tons of what I feel like are small hardware companies doing cool bleeding edge nvmeoF/arm/fpga stuff, TONS of universities with really cool looking projects, etc.
