So has anyone out there actually run any benchmarks on these machines?
Is HT really that bad compared to a specialized low latency
interconnect?

I'm configuring a small cluster for some people and the prices for 16
node x 4-core with Myrinet/Infiniband/Quadrics is close enough to a
Tyan VX50 4 node x 16-core system also with Myrinet etc. The apps that
will run are MPI based molecular dynamics and maybe some CFD code.

I tried signing up at the AMD Devcenter to get access to their
clusters for benchmarking but it's been weeks and still no response.
