The invention discloses a distributed file system-based simulation distributed parallel computing platform and method. The platform comprises multiple clients, wherein a user submits tasks to the scheduling nodes via the clients; the tasks uniformly allocated by the scheduling nodes are transmitted to multiple calculation nodes via an interchanger for participating in the calculation; after the calculation is completed, the calculation nodes send calculation results to the scheduling nodes; the scheduling nodes process the calculation results, directly write in a database or write in the database through a data interface, and inform the clients of the completing of the calculation. The distributed file system-based simulation distributed parallel computing platform and method have the beneficial effects that the input calculation data and output calculation result communication efficiency is substantially increased, thus the computing efficiency of the whole distributed parallel computing platform is greatly improved, meanwhile, the error probability of large file transfer exchange in the network congestion state can be reduced by virtue of using of a distributed file system, and the reliability and accuracy of the simulation calculation results are improved.
