Session K5 - Computational Challenges in High Energy.
INVITED session, Sunday afternoon, April 06
Commonwealth C, Loews Philadelphia Hotel
>From currently operating experiments like CDF and D0, to future BTEV and LHC era efforts, experimental High Energy Physics is today forging computing technologies to meet the challenges of tomorrow. HEP experiments continue to grow in size and complexity, as do the distributed natures of their collaborations and computing resources. Current experiments employ millions of lines of C++, Petabytes of tape storage, hundreds of Terabytes of disk cache, Gigabytes/sec network bandwidth, and TeraHertz of CPU. High speed CPU’s and networking enable additional processing to be done in real time, pushing the frontiers of on-line data filtering, as well as hardware and software reliability. New technologies in data storage and more powerful compute servers promise to empower researchers to probe ever deeper into the fundamentals of the universe by sifting through larger quantities of information faster and more efficiently. Grid technologies provide the ability to bring geographically distributed resources together and place them at the fingertips of the physicists. Larger and more geographically dispersed collaborations make communication a key element to the success of future HEP. These are among the many computing challenges to be encountered in the coming decade of Experimental HEP.
