http://setiathome.berkeley.edu/forum_thread.php?id=17664 This guy has 0 credits so can't ask here. He has Win XP 64 bit. Is there a boinc cc and seti client for 64 bit? If so are there known issues that someone could help him with. Or presumably 64 bit XP running a 32 bit application. Thanks Regards Ian  ID: 143066 ·  |

my AMD 64 runs a 32 bit OS and has no problems. I haven't heard of a Boinc core client optimized to run 64 bit. ID: 143078 · |

Since Seti is nearly perfectly fine with 32bit there is no need to run a 64 bit compiled client. But running a optimized client would bring some extra speed ;) get Tetsujis clients from Ned's page ID: 143641 · |

The 64 bit windows XP will run a 32 bit app. just fine if not a bit faster than a 32 bit os will run the same app.

OK all thanks. I'll show him this thread. Cheers Ian ID: 143975 · |

The 64 bit windows XP will run a 32 bit app. just fine if not a bit faster than a 32 bit os will run the same app. If an example helps, though the data is stll sparce, I do put up the numbers for A href="http://boinc-doc.net/site-misc/average-processing-time.php5">run times[/url] on all my computers. The two Xeons are as close to each other as I could get them. In the data available the 64-bit Xeon is faster for SETI@Home and slower on Einstein@Home. The data will start to skew again as I have now installed the optimized SETI@Home Science Application on all but the PowerMac (still to do - and - document). So, an example set of run times. Note that both are reletively recent additions so the numbers are "low" compared to the other machines, though with 4 CPUs working they will soon catch up. I update the numbers on Sunday (usually) so, this weeks "take" will be about another 1,000 total work units across all projects (currently at 455 completed). ID: 144008 · |

It's great to see people writing new optimized clients for the 64-bit hosts. I'm upgrading soon to a 64-bit system and I'm looking forward to 64-bit processing speed! Hopefully there will be an "official" upgraded client soon as well! Since Seti is nearly perfectly fine with 32bit there is no need to run a 64 bit compiled client. <a href="http://www.davidcthompson.com">David Thompson</a>, Intellectual Property Law <a href="http://www.stanford.edu/group/slaps/">Stanford Law and Policy Society</a> ID: 145840 · |

So far, what I can tell you is that there is little to no difference between the two machines. If you look at the data in my running average it looks like the 64 beats the pants off the 32 ... but that is an illusion as the switch to optimized clients also occurrect abut the time I got the 64-bit xeon. The sad news is that the advanced query works on my local MySQL but not on the older version used by the site that hosts my web pages :( Xeon-64 setiathome Optimized 41.922 4396.551 01:13:16 5793.550 01:36:33 66 setiathome 163.203 8235.640 02:17:15 10517.700 02:55:17 54 Xeon-32 setiathome Optimized 52.641 4909.261 01:21:49 6010.550 01:40:10 42 setiathome 27.453 8932.383 02:28:52 24043.400 06:40:43 783 but this shows the min/average/max with the counts done ... Seriously, 64-bit computers are not, repeat not, going to give much advantage to BOINC at all ... ID: 145995 · |

well hyper threading work better on 64 bits systems? ID: 146010 · |

The only thing that 64-bit gives you really is a much larger address space. A larger address space allows larger virtual memory space and as a normal side effect it also is usually a larger physical memory space. ID: 146084 · |

So far, what I can tell you is that there is little to no difference between the two machines. That might be true for Intel CPU´s but not for an Athlon 64. An Athlon 64 has 8 Geneneral-Purpose Registers (GPRs), 8 64 Bit Media and Floating-Point Registers (for MMX) and 8 128 Bit Media Registers (for SSE and SSE2) while running in 32 bit mode. Running in 64 bit mode it doubles the registers to 16 GPRs and 16 Media Registers for SSE and SSE2(SSE3). As the new optimized clients are capable of using SSE/SSE2 and SSE3 there should be a speed increase if they would be compiled as 64 bit binaries.  Join BOINC United now! ID: 146131 · |
