Another question : the test tool "ib_write_bw" uses the destinations' ip to test the bandwidth between two nodes, is there some tools using destination's LID to test the bandwidth or latency? -- Best Regards ! -------------- next part -------------- An HTML attachment was scrubbed...

Workshop on Parallel Programming Models and Systems Software for HEC (P2S2) Message-ID: CALL FOR PAPERS =============== Third International Workshop on Parallel Programming Models and Systems Software for High-end Computing (P2S2) Sept. 13th, 2010 To be held in conjunction with ICPP-2010: The 39th International Conference on Parallel Processing, Sept. 13-16, 2010, San Diego, CA, USA Website: http://www.mcs.anl.gov/events/workshops/p2s2 SCOPE ----- The goal of this workshop is to bring together researchers and practitioners in parallel programming models and systems software for high-end computing systems. Please join us in a discussion of new ideas, experiences, and the latest trends in these areas at the workshop. TOPICS OF INTEREST ------------------ The focus areas for this workshop include, but are not limited to: * Systems software for high-end scientific and enterprise computing architectures o Communication sub-subsystems for high-end computing o High-performance file and storage systems o Fault-tolerance techniques and implementations o Efficient and high-performance virtualization and other management mechanisms for high-end computing * Programming models and their high-performance implementations o MPI, Sockets, OpenMP, Global Arrays, X10, UPC, Chapel, Fortress and others o Hybrid Programming Models * Tools for Management, Maintenance, Coordination and Synchronization o Software for Enterprise Data-centers using Modern Architectures o Job scheduling libraries o Management libraries for large-scale system o Toolkits for process and task coordination on modern platforms * Performance evaluation, analysis and modeling of emerging computing platforms PROCEEDINGS ----------- Proceedings of this workshop will be published in CD format and will be available at the conference (together with the ICPP conference proceedings) . SUBMISSION INSTRUCTIONS ----------------------- Submissions should be in PDF format in U.S. Letter size paper. They should not exceed 8 pages (all inclusive). Submissions will be judged based on relevance, significance, originality, correctness and clarity. Please visit workshop website at: http://www.mcs.anl.gov/events/workshops/p2s2/ for the submission link. JOURNAL SPECIAL ISSUE --------------------- The best papers of P2S2'10 will be included in a special issue of the International Journal of High Performance Computing Applications (IJHPCA) on Programming Models, Software and Tools for High-End Computing.
