1) Message boards : Number crunching : Ridiculously high computation speed - what's going on here? (Message 53668) Posted 13 Mar 2012 by Collin Arneson Post: I've been running MilkyWay@home for a little while now, and I've been noticing that the multi-threaded tasks tend to run incredibly fast - as in TeraFLOPs/Second, as listed in the "properties" window after the task has been completed. Most seem to hover around 1 TeraFLOPs/Sec, but this one recently hit 11 TeraFLOPs/Sec. I run a MacBook Pro with an Intel i7 2.7Ghz CPU that has 2 physical cores and 2 more "virtual" cores (total of 4 recognized cores). In Geekbench, the maximum FLOPS-style measurement for my machine was 15.4GigaFLOPS, and that was (I think) for the Dot-Product test. I very seriously doubt that my machine is actually capable of 11 TeraFLOPS, so is there a known issue in eiher BOINC or the multi-threaded tasks that would produce such a result? I searched through the archives on this board, and I couldn't find any reports of similar occurrences, though I could have missed something. I am running BOINC 6.12.35. Here are BOINC's benchmark results: Number of CPUs: 4 3497 floating point MIPS (Whetstone) per CPU 6055 integer MIPS (Dhrystone) per CPU Totals are: 13,988 floating point MIPS Whetstone 24,220 MIPS integer MIPS Dhrystone Here's a screenshot of the "Properties" readout for the 11TeraFLOPS example: http://imgur.com/aD72C
