The total time taken to perform a typical barrier synchronization and/or aggregate communication operation using PAPERS is about 3 microseconds, including all hardware and software overhead. This is several orders of magnitude faster than using conventional networks, and is even faster than most commercial parallel supercomputers.
Despite this performance, a four-processor PAPERS unit can cost as little as $30 to build, and the complete hardware design and support software is fully PUBLIC DOMAIN.
