RaymondFO, can you list the specs of your test cruncher? The test computer is an older computer that was going to be retired. Asus P5Q 4gig ram 320gig Western Digital wd3200AAKS Intel Q9550 EVGA 460 GTX Additional Notes: 1) No OS updates will be received after the computer goes live with testing. I am trying to run the computer continuously for best possible comparable results; 2) The computer is plugged into a APC battery backup unit to help prevent short term power disturbances; 3) The hard drive was a spare that was wiped clean, re-initialized, and reformatted. The same hard drive will be used for the Windows 7 test as I will perform the same process for the hard drive when the Windows 7 test occurs; 4) No overclocking and 5) No new projects, announced or otherwise, will be included in the WU project mix. (edited/added item) The computer in question is extremely reliable and rock solid. Except for bad WU's received from the various projects in question, I cannot recall when this computer returned an invalid or error result. This computer has never experienced any problems continuously crunching only HPF2 WU's for over a month, unlike other computers that I used to have.

About file systems performance which is to me the most major ingredient, this article discusses XFS http://lwn.net/Articles/476263/ for those that have oodles of data to manage and seemingly finally matching the ext4 performance. Still have to check out what btrfs could mean to average user. Anyone tried that in it's latest incarnations?
Soon I'll be testing the I7-2670QM when the 12.04 LTS RC1 comes out in probably March. Drive has already been configured [General, Swap and BOINC partitions], still needing to figure out how to prevent a Linux dual boot install will not mangle the MBR in a way that the W7-64 install does not become a reject for SP upgrading. --//-- |

Joe, any improvements when you did this? I did not note any, nothing was apparent. I did it mainly to take pressure off the main drive, so if the drive went bellyup, I would not lose the system, just the BOINC drive. Cheers

Second drive [it's own platter], gives some marginal performance improvement. Doing this now by an allocation to an USB 3.0 ported Terabyte drive that otherwise does little but file serving [NTFS formatted].

Is it coincidence or is it not [no it is not], but every time Linux has CVE patches out for security related issues **, there's attempts being logged by my router [send by mail to me], trying to get into my Linux box, internal IP inclusive where it's trying to go. Yesterday saw 4 SSL related patches in the Update screen and applied them immediately. K-Splice continues to work admirably too... zero boot requirement.
Feb 10 22:00:13 (none) user.emerg kernel: idslog tcpresetIN=ppp_0_8_35_1 OUT=br0 SRC=63.245.209.92 DST=192.xxx.xxx.xxx LEN=40 TOS=0x00 PREC=0x00 TTL=54 ID=0 DF PROTO=TCP SPT=443 DPT=38055 WINDOW=0 RES=0x00 RST URGP=0 219 K-Splice continues to work admirably too... zero boot requirement. Of course, my router has an active firewall [double up to the software version on the computers], running on Linux too and firmwared to the latest greatest. Just that you're aware... Linux is not impervious either... don't get sloppy, like certain ISPs, Banks and Telecom providers continue to hit their heads against. ** Seeing same when Windows patch Tuesday fixes have been released... well sorry, but how dumb can it get when the router runs on Linux :P. --//-- |

Still have to check out what btrfs could mean to average user. Anyone tried that in it's latest incarnations? The linux.conf.au Jan2012 (the Kernel Report, starting from 22m30s of the video) mentioned "Butter-FS" (for Btrfs) many times while mentioning "XFS" only once. The Btrfs seems to be the focus of Linux going forward rather than XFS, and only in the future as "Ext4 will continue to grow for a while yet" says the video. That tells me that, as much as XFS shows promise, my bet is that ext4 will likely continue to be the default filesystem for Linux v12.04 and a few more versions after that -- for the desktop. As far as fileSystems go, there is this ZFS thing which this PDF promotes as "the last word in file systems".; |

Here, i am running an old Q6600 @ 3,2GHz, with 10GB of DDR3, 8 (yes eight) 7200rpm hard drive, in a RAID 5 Area with mdadm.
System is gentoo x64, under kde. Some parts of the system are compiled with ICC (Intel CC), especialy Boinc. It works fine, and smooth |

Attn Meerkat and Natty users... load your Update Manager as bugs are out to get to your crunchers:
Canonical issued last night, February 13th, new versions of the Linux kernel packages for the Ubuntu 11.04 (Natty Narwhal) and Ubuntu 10.10 (Maverick Meerkat) operating systems, fixing vulnerabilities found recently in the official Linux kernel packages. The following four Linux kernel vulnerabilities were found: CVE-2011-3353, CVE-2011-4622, CVE-2012-0038, and CVE-2012-0044. As usual, you can click on each one to see how it affects your system, or go here and here for in-depth descriptions, as it affects other Linux operating systems as well. The security flaws can be fixed if you update your system(s) to the linux-image-2.6.35-32 (2.6.35-32.65) package(s) for Ubuntu 10.10 and the linux-image-2.6.38-13 (2.6.38-13.55) package(s) for Ubuntu 11.04. For in-depth instruction about how to update your system, please follow this link: https://wiki.ubuntu.com/Security/Upgrades. Don't forget to reboot your computer after the upgrade!

Project started a little early at 8 February 2012 at 23:46:25. Ubuntu 11.10 64 bit is running first. Based upon preliminary run times from the 10.04 32 bit version, this should take several weeks and FAAH, C4CW, HPF2 and HCC are the selected projects. Any repair units received will be processed normally without the repair unit "jumping ahead" of other WU's, unless otherwise directed by WCG requests or parameters. Thought I would give an update on this ongoing project. It would appear each OS will take 4-5 weeks due to WU distribution, and underestimated run times. Here are the statistics as of 2/21/12:  I will advise when Ubuntu 11.10 test results are complete and begin the MS-Windows 7 64 bit test phase. |
