Report: Accelerating HPC Apps Through MPI Offloading
July 28, 2011 by
In this guest feature from the HPC Advisory Council, authors Gilad Shainer, Tong Liu, Pak Lui, and Richard Graham explore the advantages of offloading MPI collectives communications from the CPU to the cluster interconnect on various applications’ performance.
Abstract
In the past, performance tuning of parallel applications could be fairly accomplished by separately optimizing their algorithms, communication, and computational aspects. However, as we continue to scale future larger machines, these issues become co-mingled and must be addressed comprehensively. MPI collectives communications are frequently being used for processes synchronization and their performance is critical for scalable, high-performance applications. Optimizing collectives communication performance can be achieved by offloading these communication to the network therefore minimizing the negative effect of system noise and jitter as well as separating them from the rest of the CPU activities. Throughout application profiling we can identify applications which will greatly benefit from such offloading and can determine the associate performance and productivity benefits.
"Memory Advantage Program" to Help Researchers App-Up on World's Largest Memory Super
July 27, 2011 by
To help researchers take advantage of Blacklight, the largest shared-memory system in the world, the Pittsburgh Supercomputing Center (PSC) has launched a Memory Advantage Program. Shared memory” means that a system’s memory can be directly accessed from all of its processors, as opposed to “distributed memory” (in which each processor’s memory is directly accessed only […]
GPU.NET Version 2 Allows Developers to Code in Any .NET-Supported Language
July 27, 2011 by
This week TidePowerd announced the Version 2 release of their GPU computing solution for the .NET framework, GPU.NET. The platform allows developers to quickly write GPU-accelerated applications completely in .NET-based languages. Our core goal is to provide developers with powerful, yet easy-to-use tools for numerical and high-performance computing (HPC) – and to provide those tools […]
