Speakers will be chosen based on 1-page abstracts submitted to the ScicomP13 website by 23 April. ScicomP meetings target computational scientists and engineers interested in achieving maximum performance and scalability on all IBM HPC platforms, including the POWER, Linux, BlueGene, and Cell platforms. Presentations will be given by both HPC users and IBM staff. The focus of user presentations is on real world experiences in porting, tuning, and running codes on large-scale IBM systems. Topics may include (but are not limited to) code migration, scalable algorithms, hybrid programming models, exploiting system architectures, and scheduling and execution frameworks. IBM staff presentations include hardware and software road maps for large systems; application development support software tools; performance programming, measurement, analysis, and tuning techniques.
