User and Performance Impacts from Franklin Upgrades

Description: The NERSC flagship computer Cray XT4 system"Franklin" has gone through three major upgrades: quad core upgrade, CLE 2.1 upgrade, and IO upgrade, during the past year. In this paper, we will discuss the various aspects of the user impacts such as user access, user environment, and user issues etc from these upgrades. The performance impacts on the kernel benchmarks and selected application benchmarks will also be presented.

Multi Program-Components Handshaking (MPH) Utility Version 3 User's Manual

Description: MPH version 2 combines all features of MPH version 1, unifies the interfaces, and provides more flexible components integration/execution modes. In a distributed multi-component environment, each executable resides on a set of SMP nodes. Components within an executable may overlap on different nodes or processors. MPH Version 2 contains the following functionality: component name registration; resource allocation; multi-component single executable, multi-component multi-executable, etc.; inter-component communication; inquiry on the multi-component environment; and standard in/out redirect.

Holistic Evaluation of Lightweight Operating Systems using the PERCU Method

Description: The scale of Leadership Class Systems presents unique challenges to the features and performance of operating system services. This paper reports results of comprehensive evaluations of two Light Weight Operating Systems (LWOS), Cray's Catamount Virtual Node (CVN) and Linux Environment (CLE) operating systems, on the exact same large-scale hardware. The evaluation was carried out over a 5-month period on NERSC's 19,480 core Cray XT-4, Franklin, using a comprehensive evaluation method that spans Performance, Effectiveness, Reliability, Consistency and Usability criteria for all major subsystems and features. The paper presents the results of the comparison between CVN and CLE, evaluates their relative strengths, and reports observations regarding the world's largest Cray XT-4 as well.
