摘要：

We describe a new 512-CPU Linux Beowulf cluster built at Toronto dedicated to problems in computational astrophysics. The cluster incorporates a new network topology based on inexpensive, 24-port gigabit switches and exploitation of a second gigabit port on each server. This topology provides network performance competitive with more expensive networking configurations. Our speed rating is 1.11 Teraflops on 512 CPUs according to the HPL Linpack benchmark on the Top 500 Supercomputers list. We also describe some preliminary results from our first simulations on this new machine.
