The use of last generation Programmable Components make possible the
construction of very powerful and competitive special purpose computers.
We have designed, constructed and tested a three-dimensional Spin Glass
model dedicated machine. Each single board can simulate 8 different
systems, updating all the systems every clock cycle at 50 Mhz. The on-board
reprogramability permits us to change easily the lattice size, or even the
update algorithm or the partition function.
Here we present the first runs using two algorithms: Demon and Heat Bath.
The machine includes a component dedicated to random number generation,
which provides us with a 32 bits random number every cycle, as needed in
the Heat Bath algorithm. The update speed of the whole machine, composed
of 12 boards, is 217ps/spin.
