Hi Everyone Nice to be crunching units again. I have just commissioned a new box Small compact with a hungry heart A Beast with an Intel P4 640 as it's core. works fine. I have commited 2 cardinal sins thou. The unit uses an ASUS 915GL Barebone Chassis. (I need the space.) I put some Performance Memory to compensate for this thou. The second sin is I havn't got round to sorting out a 64Bit Operating System. I am using Win XP PRO 32Bit The issue I have noticed is that the server reports the cache memory as only having 976.56Kb. This processor has 2048Kb THen I decided to check my old Unit It show 976.56Kb even stranger as it only has 512Kb. I jyust checked all my boxes They all seem to have nearly a Megabyte of cache. including Celeron and AMD. <img border="0" src="http://boinc.mundayweb.com/one/stats.php?userID=2104" /> |

Yes, it's a standard setting in the Boinc server version. If I am not mistaken, it can be read correctly by the newer CVS versions, but when a project doesn't upgrade to one of them, it'll continue showing this standard setting. Then again, not all projects use L2 cache that much as others do. Seti uses it more than Einstein, for instance. Not sure if LHC does. Jord BOINC FAQ Service |

Well, SETI@Home still thinks my Xeon with 2M cache is only 1M ... and I am running the 4.45 client. |

outside of the boinc client, there is the OS like XP, w2k, w3 configuring the cpu cache size while installation... could you take a look to a certain registery entry, please? open regedit in the section HKEY_LOCAL_MACHINE in System\\CurrentControlSet\\Control\\Session Manager\\Memory Management there must be a reg_dword entry called SecondLevelDataCache What's the value there? Is it 0?? the default value is "0". This would mean, *your* system are set to DEFAULT of 256 k. confusing the client state reports the propper value of <m_cache>1000000.000000</m_cache> =1 MB anyway didn't saw a *huge* difference in crunching time. |

Hi Ric Thanks for the information I have adjusted this and rebooted. I am going to investigate further. <img border="0" src="http://boinc.mundayweb.com/one/stats.php?userID=2104" /> |
