Portals 3.3 on the Sandia/Cray Red Storm System
نویسندگان
چکیده
The Portals 3.3 data movement interface was developed at Sandia National Laboratories in collaboration with the University of New Mexico over the last ten years. Portals is intended to provide the functionality necessary to scale a distributed memory parallel computing system to thousands of nodes. Previous versions of Portals ran on several large-scale machines, including a 1024-node nCUBE-2, a 1800-node Intel Paragon, and the 4500-node Intel ASCI Red machine. The latest version of Portals is the lowestlevel network transport layer on the Sandia/Cray Red Storm platform. In this paper, we describe how Portals are implemented for Red Storm and discuss many of the important features and benefits that Portals provide for supporting various services in the Red Storm environment.

A portion of the Cray Red Storm system at Sandia National Laboratories recently completed an upgrade of the processor and network hardware. Single-core 2.0 GHz AMD Opteron processors were replaced with dual-core 2.4 GHz AMD Opterons, while the network interface hardware was upgraded from a sustained rate of 1.1 GB/s to 2.0 GB/s (without changing the router link rates). These changes more than d...
متن کاملImplementation of Open MPI on Red Storm
The Open MPI project provides a high quality MPI implementation available on a wide variety of platforms. This technical report describes the porting of Open MPI to the Cray Red Storm platform (as well as the Cray XT3 platform). While alpha quality, the port already provides acceptable performance. Remaining porting work and future enhancements are also discussed.
متن کاملRed Storm Systems Management: Topics on Extending Current Capabilities
Systems like the Red Storm system at Sandia Laboratories provide grand challenges for developers of systems software. While many of the challenges associated with systems like Red Storm are experienced on other systems, like commodity clusters, the sheer magnitude of the system magnifies issues that may seem trivial on less complex systems. The value of taking an integrated approach to many of ...
