Hi!
----------------------------------------I'm user of 32-bit Windows 7. I thinking about change it into 64-bit version, to increase BOINC computation speed. I know that C4CW project has a 64-bit application, but what is speed difference between 32-bit version of it? Is higher, or similar? [Edit 1 times, last edit by Dejvus at May 7, 2012 12:45:28 PM] |

Can only speak for My comps. 6-8% going on 64 bit W7-64 from the 32 bit C4CW to the 64 bit C4CW. Generally the 32 bit versions of all the sciences execute a bit faster on 64 bit OSses. Since buying a W7 upgrade, the kit actually came with both disks, so if your system supports 64 bit, go for it (but be aware that some old legacy software wont even run in 32 bit compatibility mode).

To add: Here the official announcement of the 64 bit version. https://secure.worldcommunitygrid.org/about_us/viewNewsArticle.do?articleId=157
In the future, WCG will implement testing of each host if both 32+64 bit are available to determine which of the 2 for a specific host processes faster. Some devices execute slower with 64 bit compiles. The test would comprise a series of maybe 10-20 tasks of each bit size. We'll know when it gets here. --//-- |

Reminder: If you go to a 64-bit operating system, to run 64-bit science programs you have to upgrade to a 64-bit version of BOINC (AFAIK).
When comparing work throughput, an increase in points per hour with 64-bit BOINC can be misleading. This is because the 64-bit BOINC client will generate a higher integer benchmark score than the 32-bit client running under the same 64-bit o/s. BOINC clients claim points based on the CPU benchmarks, and with some WCG projects the inflated claim influences the points awarded by the WCG server. This effect makes it difficult to measure the true benefit (if any) of moving to 64-bit science programs. |

This isn't too big acceleration, but always something positive. :D I don't expected information about speedup normal 32-bit applications, I expected rather small slow down, due to emulation process.
PS For old, non-working software I have VirtualBox with 32-bit Windows XP on board. ;) |

Actually, Rickjb, NO, no upgrade required for anyone who's on BOINC 6.10 (actually mentioned in the news art). As for credit, WCG BOINC server 700 gives a dang about what clients claim, benchmark, whatever. The actually performed work is measured and compared to hosts doing same in a complicated way, on which I'm not going to try to expand. --//-- |
