BOINC Exceeds 2 Petaflop/s Barrier 114
Myrrh writes "Though an official announcement has not yet been made, it would appear that the BOINC project as a whole has exceeded two petaflop/s performance. The top page features this legend: '24-hour average: 2,793.53 TeraFLOPS.' According to last month's Top500 list of supercomputers, BOINC's performance is now beating that of the fastest supercomputer, RoadRunner, by more than a factor of two (with the caveat that BOINC has not been benchmarked on Linpack)."
Still far behind... (Score:5, Informative)
Folding@home [wikipedia.org], which has passed 5 petaflops on February. Note that Folding is a single project, while the Petaflop measurement for BOINC are the aggregate total for that platform, which runs many independent and often unrelated projects.
Getting that thing bundled on PS3 was brilliant.

Sigh...why do these projects (BOINC, *@home, etc.) insist on comparing their performance to superpercomputers on the TOP500 list? Of course BOINC has not been benchmarked on Linpack. If it was, the performance wouldn't come close to anything at the top of the TOP500 list. A bunch of workstations running a grid client and talking to each other over the internet is never going to have the same type of message passing bandwidth as a supercomputer using something like locally connected infiniband.

Actually I run the Linpack HPL here at the lab, once with two clusters (one 228 nodes 4cpus x 4cores each x 4 float ops per cycle, and one 1152 node cluster of the same AMD configuration) we hit 1.069 MegaWatts and I started peeling the paint off of a huge transformer in the basement. I had to do one at a time. Linpack is a power pig with double precision floating point if your cpu/thread/mpi balance is correct.
