From EETimes.com: "Promising a significant boost in Verilog simulation
speeds, Avery Design Systems Inc. has released a product that lets users
run one simulation job in parallel on multiple CPUs. Originally part of
Avery's VCK Verilog simulation and testbench environment, the
SimCluster product can now be licensed separately for use with
third-party Verilog simulators.
As a distributed simulation manager, SimCluster handles synchronization
and communication between simulation runs. It can be used with
multiple-CPU symmetric-multiprocessing machines such as Sun ES450
and ES4500 workstations, or over distributed networks of single-CPU
machines such as Linux PCs."
