Contention-Aware Kernel-Assisted MPI Collectives for Multi-/Many-Core Systems


Multi-/many-core CPU based architectures are seeing widespread adoption due to their unprecedented compute performance in a small power envelope. With the increasingly large number of cores on each node, applications spend a significant portion of their execution time in intra-node communication. While shared memory is commonly used for intra-node… (More)
