Fast Transfer of Shared Data

Carl Timmer
 Thomas Jefferson National Accelerator Facility

Presented by: Carl Timmer

  The Event Transfer (ET) system enables its users to produce events (or data) and share them with other users by utilizing shared memory on either Solaris or Linux based computers. Its design emphasizes speed, reliability, ease of use, and complete recoverability from all crashes. In addition to fast local operation, the ET system allows network transfer of events. Using multithreaded code based on POSIX threads and mutexes, a successful implementation was developed which allowed passing events up to almost 500kHz on a 4 cpu Sun workstation and 150kHz on a dual cpu PC.
