Overview

In the Spring of 2008, PERI was directed by DOE SC to conduct a study of affinity of twelve Petascale pioneering applications to different computer architectures. The intention was to be able to use this information to inform DOE’s ten-year facilities planning. In response to this charge, PERI has formed an Architecture Tiger Team:

• Team Lead: Bronis de Supinski
• Team: Heike Jagode (UTK and ORNL); Sadaf Alam, Roth, Vetter, Worley (ORNL); Carrington, Olschanowsky, Tikir (SDSC); Bailey, Shan, Gunter (LBNL); Shende, Malony (UO)

Performance database

Performance data are stored on a performance database hosted at perfdb.renci.org. It is a PostgreSQL (8.1.11) server running on TCP port 5432.

It accepts remote SSL connections, currently only for user 'peri' and database 'tau'.

To connect, get the value for <PASS> then run the PostgreSQL client, psql:

psql "host=perfdb.renci.org dbname=tau user=peri password=<PASS> sslmode=require port=5432"
