Presented by: Carlos Ungil

  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.
