Advanced Message Passing and Threading Issuesdreds of thousands of processors, each one composed of by several semi-specialized cores. From a pure performance view point such architectures appear very promising, even if the most suitable programming methods from the users view point have yet to be discovered. Currently both message passing and

Using MPI-2: A Problem-Based Approach the MPI Forum. Such topics include dynamic process management, one-sided communication, and parallel I/O. These features are now available in multiple vendor and freely available MPI implementations. Rather than present this material in a standard ”reference manual” sequence, we will provide detail

Some Improvements to a Parallel Decomposition Technique for Training Support Vector Machineschine. At each iteration of the technique a subset of the variables is optimized through the solution of a quadratic programming subproblem. This inner subproblem is solved in parallel by a special gradient projection method. In this paper we consider some improvements to the inner solver: a new alg

Computing Frequent Itemsets in Parallel Using Partial Support Trees a database of transactions. A number of sequential algorithms have been proposed that accomplish this task. In this paper we study the parallelization of the partial-support-tree approach (Goulbourne, Coenen, Leng, 2000). Results show that this method achieves a generally satisfactory speedup, whil

Efficient Implementation of Allreduce on BlueGene/L Collective Networkon scalability is a crucial issue for a system of such size. On BlueGene/L scalability is made possible through the efficient exploitation of special communication. The BlueGene/L system software provides its own optimized version for collective communication routines in addition to the general purp

Scalable Fault Tolerant MPI: Extending the Recovery Algorithmt restart schemes. The initial implementation of FT-MPI included a robust heavy weight system state recovery algorithm that was designed to manage the membership of MPI communicators during multiple failures. The algorithm and its implementation although robust, was very conservative and this effect

Hash Functions for Datatype Signatures in MPIfunctions based on checksums to encode the type signatures of MPI datatype. The quality of these hash functions is assessed in terms of hashing, timing and comparing to other functions published for this particular problem (Gropp, 7th European PVM/MPI Users’ Group Meeting, 2000) or for other applica
