Install new "fast" computers for h1susex, h1susey
WP 5728, Dave, Jim, Carlos

Install newer "Fast" computers for h1susex, h1susey.  These are the computers which were briefly installed in July of 2015 and were removed because they caused timing, ADC, and IPC errors.

The BIOS parameters for the computers are set to the optimal default with the exception of hyperthreading is turned off, the computers are set to stay off on power loss, the CPU power profile is set to maximum performance, and the boot order is changed to only look for DVD or PXE boot.  Initially, a much more restrictive set of parameters was tried, which disabled nearly all of the features settable from the BIOS, but it was found the models wouldn't run.

We have done nothing to correct the timing, ADC, and IPC errors which were observed in July.  We are monitoring the error rate so we have a good baseline for possible fixes in the future.
