For those of you running Linux 64, guess I doesn't matter what flavor, need a little assistance. I'm running ubuntu 64 11.4 on one of my crunchers. Looks like GFAM, DSFL and HCMD2 seem to loose anywhere between 5 to 12 minutes of actual time vs CPU time. My win7 64 rig looses only about a minute. Is this normal? Starting to wonder if my hard drive is having issues. This rig has a xeon x5650 hex with 12gb ram. Suggestions? I run Linux Mint, but only have run HCC on this OS. I have not noted any significant difference in actual versus CPU time, but they only take a little over an hour. Core 2 Duo 6600. Cheers

Cheers Under the disk utility you should see the SMART status of you disk. Or open a terminal and run this $ sudo smartctl -t long /dev/sda over night. Just man smartctl for all the options. |

Suggest you reapply thermal paste. What kind of laptop is it? Maybe install a fan control software to bump the fans higher. Seems awfully warm. This is Lenovo T61. I think paste part is fine because this does not get hot around CPU socket. On another hand, gets very hot from corner where heatpipes are attached to heatsink. So heat is moving where it suppose to go. Played round with TP Fan Control and notice that propeller cannot go any faster than öbaut 3800 rpm. So it seems to me that this model has been planned to run hot. On newer one T410 these is lot better (louder, keeps high whizzing noice) fan, it seems to run very cool also from bottom. This sure is joy    [Edit 1 times, last edit by ultimaThule at Dec 5, 2011 9:39:05 AM] |

Already looked at smart status which indicates its good. This disk has seen 2 upgrades with ubuntu. Might just wipe and clean install fresh OS. Have been contemplating installing on a cheap SSD I got last year. Its only a 30GB. What I dont know is whether TRIM is supported under ubuntu. Anyone know for sure if it does?

Cheers HCC never gave me any issues. Ran pretty good on ubuntu. Starting to wonder if running 11 out of 12 threads has anything to do with this. Time to reduce one just to see if this helps.

Still some heat stuff, well actually more economics....
----------------------------------------50 pieces of candles cost 3,32 USD. One piece release 100W and burn 4h, so fifty piece carries 20kWh. So price of heat kilowatt is 11,5c (0,15 US). Average electric price here is 13c-18c (depending consuming level), well before next years tax raises when government aim is collect 700M€ more taxes raising energy taxes. This country does not make any sense again  [Edit 2 times, last edit by ultimaThule at Dec 5, 2011 10:27:41 PM] |

Youmight be running up against an I/O bottleneck someplace. It could be anyplace you have data going. the slowest, I think is your disk I/O. It could be the memory bus or FSB, but unless you have a lot of data flowing, I would check your disk activity. That many cores could be generating a lot of data. If a core has to wait for data it will be standing in a wait state and lose time. Cheers

Weird that Ubuntu looses this time but win7 running 22 thread only looses around 1 minute. Thought linux was more efficient than windows. When I get time, will move everything to my cheap ssd to see what happens.

Just checked two wu's completed at a little over 4 hours. One has a difference of around 3 minutes, the other around 7 minutes. This is just nuts. Just made a few changes in the bios to see if any changes. Starting to wonder if the projects favor windows more than Linux. The hard drive is about 4 years old so still think it could be part of the problem.
----------------------------------------Is there a program for ubuntu that would move the entire boinc project to another disc? I have climate prediction projects that last a couple months I don't want to abort, otherwise I would finish what I have and reinstall to a ssd.
