Currently GPU is used as a coprocessor to accelerate computation in heterogeneous concurrency systems comprised of CPU and GPU. However, the architecture of main core plus coprocessor needs extra spending on communication. An effective method to solve this problem is to process data in batches in ...
Efficient Communication/Computation Overlap with MPI+OpenMP Runtimes CollaborationParallel computingDistributed computingRuntime systemsRuntime collaborationOverlap network communications and computations is a major requirement to ensure scalability of HPC applications on future exascale machines. To this purpose the...
introduces activation (gradient) all-gather and reduce-scatter as shown in the below figure. NeMo provides various options to overlap the tensor-parallel (TP) communications with computation. The TP communication without direct computation dependency are overlapped with the computation in bulk ...

DeepSpeedZeroOptimizer.average_tensoronly sets reduction stream waiting for default stream. This is ok in cases where the computation time is longer than the communication time, but when the communication time is longer, it may result in a rewrite of the ipg_buffer when the communication is not...
We propose MapReduce with communicationoverlap (MaRCO) to achieve nearly full overlap via the novel idea of including the reduce in the overlap. While MapReduce lazily performs reduce computation only after receiving all the map data, MaRCO employs eager reduce to process partial data from some ...
