A massively parallel scheme for gas adsorption in zeo lite molecular sieves based on the Macro State Markov Chain Model (Chen, 1993; Chen and Hirtzel, 1993a) has been developed and implemented on the Connection Machine CM2. Implementation details that are impor tant in achieving high efficiency of the parallel algo rithm are described. The results show that the parallel implementation is very efficient, and that simulation time is dramatically reduced in comparison with con ventional sequential schemes.
