ParaLEX: A Parallel Extension for the CPLEX Mixed Integer Optimizera master-worker parallelization specialized for the solver on a PC cluster using MPI. To fully utilize the power of the solver, the implementation exploits almost all functionality available in it. Computational experiments are performed for MIPLIB instances on a PC cluster composed of fifteen 3.4GH

Test Suite for Evaluating Performance of MPI Implementations That Support ,erent threads making MPI calls, the ability to overlap communication with computation, and other features. We present performance results with this test suite on several platforms (Linux cluster, Sun and IBM SMPs) and MPI implementations (MPICH2, Open MPI, IBM, and Sun).

Process Cooperation in Multiple Message Broadcastoptimal. Empirical study shows that it outperforms other widely used algorithms significantly when the data to broadcast is large. Efficient communication schedule construction is a salient feature of this algorithm. Both the basic schedule and the cooperation schedule are constructed in .(log.) bitwise operations on process ranking.

Self-consistent MPI Performance Requirementsverify whether a given MPI implementation fulfills basic performance requirements. We present examples where some of these requirements are not satisfied, demonstrating that there remains room for improvement in MPI implementations.

In this article, we present a . that considerably lowers this barrier by providing complex network environments on a single computer and thus enables testing in situations where it otherwise would not be feasible.

Parallelizing Dense Linear Algebra Operations with Task Queues in llcard that allows an elegant implementation of irregular parallelism. We evaluate our approach by comparing the OpenMP and . parallelizations of the symmetric rank-k update operation on shared and distributed memory parallel platforms.
