Abstract—Using MPI as communication interface, one or several applications may introduce complex communication behaviors over the network cluster. This effect is increased when n...
Scalability and reliability are inseparable in high-performance computing. Fault-isolation through hardware is a popular means of providing reliability. Unfortunately, such isolat...
—In this paper, we analyze restrictions of traditional models affecting the accuracy of analytical prediction of the execution time of collective communication operations. In par...
