Order Preserving Event Aggregation in TBONs,vent orders. We implement this algorithm in our tool infrastructure that provides TBON functionality as one of its services. We demonstrate that our approach provides scalability with experiments for up to 2048 tasks.

FLASK

Multi-core and Network Aware MPI Topology Functions,lusters with multi-level networks. Micro-benchmark results show considerable improvement in communication performance when using weighted and network-aware mapping. We also show that the implementation can improve communication and execution time of the applications.

BOOM

Improving the Average Response Time in Collective I/O,umber of processes per file stripe and the number of accesses per process. Our experimental results demonstrate improvements of up to 50% in the average response time using two synthetic benchmarks and a high-resolution climate application.

Experience of a PRACE Center,p 10 system 15 years ago would be in the range of 100 KW the most recent list shows systems in the range of 1- 2 MW and more. This factor of 10 makes costs for power and cooling a significant issue. The second financial issue is the increase in investment cost for such systems.
