2) Message boards : Number crunching : Sixtrack (notag/sse2/pni/sse3) (Message 27798) Posted 16 Aug 2016 by Carsten Milkau Post: I recently noticed that credit on sixtrack is surprisingly low, compared to other projects (about a factor 3-4 below expectation). I checked the WU and noticed two differences[1] to other users: 1) WU take 10-15x longer to complete on my machine 2) Other users run "Sixtrack (sse2)", while I run "Sixtrack" (without tag) My CPU is 5y old, so that might already explain everything, but I'm worried about that SSE2 tag. If I'm using a non-SSE implementation, that would fit very well with that factor 3-4 performance gap. My CPU supports SSE2, SSE3, SSE4.1 and SSE4.2 (it's an Intel i7 920). If the (notag) Sixtrack is without SSE2, how do I make boinc use the SSE2 version? [1] http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=46101520
