Triggered operations and counting events or counters are building blocks used by communication libraries, such as MPI, to offload collective operations to the Host Fabric Interface (HFI) or Network Interface Card (NIC). Triggered operations can be us

Many-core architectures such as the Intel® Xeon PhiTM provide dozens of cores and hundreds of hardware threads. For these machines, a basic MPI implementation is inefficient, as it does not take advantage of the shared data across the ranks on the s

Supercomputers have seen an exponential increase in their size in the last two decades. Such a high growth rate is expected to take us to exascale in the timeframe 2018-2022. But, to bring a productive exascale environment about, it is necessary to f

This paper provides an in-depth analysis of the software overheads in the MPI performance-critical path and exposes mandatory performance overheads that are unavoidable based on the MPI-3.1 specification. We first present a highly optimized implement

State space search problems abound in the artificial intelligence, planning and optimization literature. Solving such problems is generally NP-hard, so that a brute-force approach to state space search must be employed. Given the exponential amount o
