Shared Receive Queue Based Scalable MPI Design for InfiniBand Clusters
White Paper A high-performance scalable MPI design is crucial for MPI applications in order to exploit the massive potential for parallelism in these very large clusters. MVAPICH is a popular implementation of MPI over InniBand based on its reliable connection... [04 Aug 2008]
Object-Based Adaptive Load Balancing for MPI Programs
White Paper MPI) for distributed memory machines. On the other hand, traditional run-time systems for MPI do not support dynamic load balancing. This paper describes an implementation of MPI, called Adaptive MPI (AMPI) that supports dynamic load balancing and... [10 Jul 2008]
NetEffect PCI-Express 10-Gigabit iWARP Ethernet: A Performance Study
White Paper This white paper presents the performance of the NetEffect PCI Express 10-Gigabit iWARP Ethernet adapter at the NetEffect verbs layer and the MPI implementation. At the MPI level, the paper presents the basic latency and bandwidth, aggregate... [04 Jul 2008]
Localized Message Passing Structure for High Speed Ethernet Packet Switching
White Paper To evaluate these two structures and produce throughput projections the paper has utilized MPI. The results show that for a hardware implementation of this switch in .18um technology, assuming a 200 MHz clock rate for the processing elements and... [04 Jul 2008]
Running HPL LINPACK on IBM p690 eServer pSeries Clusters With SP Switch2-PCI Interconnect
White Paper HPL uses MPI to run a single LINPACK calculation in parallel across multiple servers. This paper reflects the author's own experience running LINPACK on an affinity logically partitioned p690/SP Switch2-PCI cluster, containing eight p690s, where... [03 Jul 2008]
Extending OpenMP to Clusters
White Paper In the past, OpenMP has been confined to Symmetric Multi-Processing (SMP) machines and teamed with Message Passing Interface (MPI) technology to make use of multiple SMP systems. A new system, Cluster OpenMP, is an implementation of OpenMP that can... [31 May 2008]
Teaching Tools for Parallel Processing
White Paper PVM and MPI allow students to treat a network of workstations as a message passing MIMD multicomputer with distributed memory. Parallaxis is a sophisticated SIMD simulator which runs on a variety of platforms.jBACI shared memory simulator supports... [04 Mar 2008]
IBM e326m Performance for HPC
White Paper The analysis includes memory bandwidth and latency, floating-point vector performance, performance of the SPEC CPU2000 speed and rate benchmarks, and both uni- and bidirectional traffic over the PCI-Express I/O slot using a high-speed InfiniBand... [26 Apr 2007]
PMB-2.2.1 Benchmarking on POWER4+ Platforms p655+ and p690+
White Paper The MPI-I output results, without modification, are shown in graphical format in this paper. Point-to-point performance was measured between two processes within the same node (memory performance), or between two nodes (network performance). [21 Sep 2004]
Ultra-High Performance Communication with MPI and the Sun Fire Link Interconnect
White Paper The Sun MPI library uses the RSM interface to implement a highly efficient memory-to-memory messaging protocol in which the library directly manages buffers and data structures in remote memory. We discuss the characteristics of the interconnect... [25 Feb 2004]
