Abstract

PORS is a system designed for on-line event reconstruction in high energy physics (HEP) experiments. It uses the CPREAD reconstruction program. Central to the system is a parallel in-memory database which is used as communication medium between parallel workers. A farming control structure is implemented with PORS in a natural way. The database provides structured storage of data with a short life time. PORS serves as a case study for the construction of a methodology on how to apply parallel in-memory databases to HEP software, providing systematic structuring of HEP data, easier parallelization and consequently a simpler development and maintenance of code. PORS runs on a SPARCcenter 2000 8-node shared memory computer.
