Description
In the process of modularizing the molecular dynamics simulation library FMSolvr of JSC, we do not only want to improve our numerical methods but also take a look at communication and whether we can achieve an improvement on that front. We conducted a systematic literature review to see what has already been done in this field and picked out two promising communication schemes for further analysis: Shift communication as by Plimpton (1993) and a processor team-based approach by Driscoll, Georganas and Koanantakool (2013). Now, we are focused on finding a formal way of modelling these approaches in the hopes that it will help us with finding a formula for the trade-off point between one and the other method. The calculation of this trade-off point will be part of the communication module, which based on the result decides which communication method is best applied for the given input values of the simulation.
