Monte Carlo Implementation on the Connection Machine 2; Water in Graphite Pores

Abstract
The implementation of Monte Carlo (Canonical and Grand Canonical Ensembles) codes on the Single Instruction Multi Data parallel supercomputer Connection Machine 2 are discussed and demonstrated. The program was developed for the simulation of water behavior in slit graphite pores in CM FORTRAN. A one dimensional data layout is the most suitable for MC realization on the CM-2. The code performance is compared with the performance of sequential and parallel codes on other computers. Preliminary results of the simulations are reported.
