[[NSC]] participates in this project as the PRACE collaborator, with the aim of designing and implementing parallel I/O for sequence alignment softwares. <br /> <br /> This project is a user support task under PRACE 2IP WP7.1, whose project ID is 2010PA1155.<br /> <br /> == Implementation ==<br /> Implementation procedure is as follows.<br /> <br /> * Analysis on Code Structure<br /> * Design of parallel I/O interface for sequence alignment input<br /> * Implementation to the ClustalW Software<br /> <br /> The code basically adopts the master-slave structure, so that the deployment of parallel I/O which is the collective operation necessitates the change on the structure of the code. [[NSC]] designed and experimented the parallel I/O strategy for sequence alignment softwares, by adopting the sub-group communicator. [[NSC]] endeavoured to optimize I/O-related variables for the best performance of sequence data input, and applied the designed implementation to the ClustalW software.<br /> <br /> == Results ==<br /> The employed scheme provides up to 6.8 times speed-up for sequence data input in case of using 8192 cores under BlueGene/Q system. Experiments provide the guideline to set various parameters for best I/O performances.

This project aims for benchmarking the performance of NEMO oceanography code on Tier-0 PRACE resources. [[NSC]] is in charge of performing the benchmark and analyzing its result on CURIE system. NSC experimented on optimal compilation option set (performance optimisation set to -O3 -ipo -xAVX), and performed the benchmark runs which results in good scalability. NSC also contributed in incorporating the code to run under JuBE European Benchmark Framework.

He takes the role of performing some benchmark analyses by using HPCC, P-SNAP and mixedMode tools.<br /> * HPCC is a famous benchmark tool which consists of 7 sub-benchmarks, including a famous HPL tool which measures Linpack performance and STREAM benchmark which measures the sustainable memory bandwidth.<br /> * P-SNAP is a tool to measure the system noise.<br /> * mixedMode is a tool to instrument communication bandwidths of different communication modes (collective and point-to-point communications in various configurations).<br /> <br /> ----- Abstract<br /> We took benchmark runs of HPCC, P-SNAP and mixedMode on Tier-0 CURIE Bullx cluster. HPCC runs were performed to figure out Linpack benchmark performance up to 1024 cores, memory bandwidth, and cache miss ratio. P-snap measured the system noise, and mixedMode evaluates different MPI kernel performances on single-, tunneled- and threaded-mode. Those results are reported in PRACE 1-IP final report.<br /> <br /> Full details will be updated [http://www.nsc.liu.se/~sko/Projects/Synthetic_Benchmarks/ here].<br /> == Members ==<br /> {{#ask: [[Category:Person]] [[project::{{PAGENAME}}]]<br /> |?centre<br /> |?role<br /> |?field<br /> }}</div>

[[NSC]] designed and experimented the parallel I/O strategy for sequence alignment softwares, by adopting the sub-group communicator. [[NSC]] endeavoured to optimize I/O-related variables for the best performance of sequence data input, and applied the designed implementation to the ClustalW software.<br /> <br /> == Results ==<br /> The employed scheme provides up to 6.8 times speed-up for sequence data input in case of using 8192 cores under BlueGene/Q system. Experiments provide the guideline to set various parameters for best I/O performances.
