This paper explores two strategies for implementing multi-time-step explicit time integration procedure for computational heat transfer in data parallel mode on massively parallel computer, namely, the Connection Machine CM-5. Data layout, amount of communication, communication routing and load balancing are the main issues which hinder the efficiency of data parallel implementation. Among these timings, more than 70% of total time is spent performing communications for explicit finite element method. To reduce the amount of communication time and to improve the overall efficiency, two multi-time-step implementation strategies, namely, masking and grouping are discussed in this paper.
