MPIBlib: Benchmarking MPI Communications for Parallel Computing on Homogeneous and Heterogeneous Clusters
نویسندگان
چکیده
In this paper, we analyze existing MPI benchmarking suites, focusing on two restrictions that prevent them from a wider use in applications and programming systems. The first is a single method of measurement of the execution time of MPI communications implemented by each of the suites. The second one is the design of the suites in the form of a standalone executable program that cannot be easily integrated into applications or programming systems. We present a more flexible benchmarking package, MPIBlib, that provides multiple methods of measurement, both operation-independent and operation-specific. This package can be used not only for benchmarking but also as a library in applications and programming systems for communication performance modeling and optimization of MPI operations.

متن کاملFailure Resilient Heterogeneous Parallel Computing Across Multidomain Clusters
We propose lightweight middleware solutions that facilitate and simplify the execution of failure-resilient MPI programs across multidomain clusters. The system described in this paper leverages H2O, a distributed metacomputing framework, to route MPI message passing across heterogeneous aggregates located in different administrative or network domains. MPI programs instantiate a specially writ...

متن کاملRing Algorithms on Heterogeneous Clusters with PVM: Performance Analysis and Modeling
We analyze the performance obtainable on heterogeneous computing systems with data-parallel ring algorithms for the computation of longand short-range interactions. The algorithms were originally developed for homogeneous parallel systems, where they yield a nearly linear speed-up. Two heterogeneous platforms are considered: a network of ALPHA Unix workstations and a network of Pentium PCs with...
متن کاملMulti-level parallelism for incompressible flow computations on GPU clusters
We investigate multi-level parallelism on GPU clusters with MPI-CUDA and hybrid MPI-OpenMP-CUDA parallel implementations, in which all computations are done on the GPU using CUDA. We explore efficiency and scalability of incompressible flow computations using up to 256 GPUs on a problem with approximately 17.2 billion cells. Our work addresses some of the unique issues faced when merging fine-g...
