Abstract:

A parallel module for the multiblock structured mesh computing has been designed and implemented in the JASMIN infrastructure. In this module,a blocks’ relationship description algorithm and a unified communication schedule have been designed and adopted,which effectively solves the communication bottleneck broadly existing in multiblock structured mesh parallel computing.Meanwhile,by encapsulating parallel computing strategies,such as distributed storage,data communications,etc., and providing standard interfaces,this module can help the user conveniently realize multiblock structured mesh parallel computing.According to our test results,applications based on this module can be run efficiently on thousands of processors,which proves the module’s satisfying parallel computing performance.
