I don't have a super computer, but my CPU processing time compared to my wingman is way quicker. I've only processed 15 WU so maybe it's just a fluke. All of them have completed valid, except for one that error'd which all other wingmen did also.
----------------------------------------I've got an Intel® Pentium® Processor E5300 (2M Cache, 2.60 GHz, 800 MHz FSB) dual processor and running Slackware Linux 13.1 x86. Maybe the 1 MB per processor L2 cache is the speed demon? Anyone else with 1.5 to 2 hour CPU processing times? Here's some examples: 200193_ 530_ A.20.C18H13NS.35.2.set1d06_ 1-- 619 Valid 7/23/10 07:49:13 7/23/10 17:05:26 7.11 E200193_ 530_ A.20.C18H13NS.35.2.set1d06_ 0-- 619 Valid 7/23/10 07:48:12 7/23/10 18:03:59 1.52 <==== Me E200203_ 099_ A.20.C17H15NSSi.11.set1d06_ 1-- 619 Valid 7/26/10 13:11:41 7/26/10 20:36:00 1.43 <==== Me E200203_ 099_ A.20.C17H15NSSi.11.set1d06_ 0-- 619 Valid 7/26/10 13:09:11 7/27/10 12:53:57 12.00 E200197_ 740_ A.21.C18H11N3.126.set1d06_ 1-- 619 Valid 7/24/10 17:48:52 7/25/10 07:46:48 1.29 <==== Me E200197_ 740_ A.21.C18H11N3.126.set1d06_ 0-- 619 Valid 7/24/10 17:47:29 7/25/10 00:28:39 5.50 [Edit 1 times, last edit by codes at Jul 27, 2010 4:41:13 PM] |

Just in case there's something corrupted with my WCG software install, I'll let the current WU's complete, then reinstall the application to see if that changes anything. I don't have confidence in the low CPU times being reported.

codes,
Please look at your results again, and click on the word "Valid". It'll let you know how many steps your computer ran. Also, that 12 hour work unit could have been paired with an extremely slow machine. I have one that is a celeron 500 Mhz running for testing. I'm sure others have slow linux boxes as well. But look at the valid logs, if you could post what they show in the logs. No reason to reinstall unless we can see something wrong. -Uplinger |

Here's my E200203_ 099_ A.20.C17H15NSSi.11.set1d06_ 1-- 619 Valid 7/26/10 13:11:41 7/26/10 20:36:00 1.43
my wingman says 12 for CPU Time hours that he processed it. I don't see any errors in the "Messages" log. It just amazes me that my processor can be that fast compared to others if those are true CPU times. Maybe time slows down at my house?  <core_client_version>6.10.17</core_client_version> <![CDATA[ <stderr_txt> INFO: No state to restore. Start from the beginning.

The log says it took from 11:05 to 15:52 which is essential 4.75 hours, so I wonder how only 1.43 gets to be reported. My quad does them in about the same wallclock time but the difference with CPU time is only 10-30 minutes depending on whether the system is used or not (BOINCTasks logs both from remote)

Same comment as Sekerob's: my wallclock times are consistent with yours and Sekerob's, but the CPU times are more than twice yours, in the 4-hour range (with a Q6600 at 3.07 Ghz, 8 MB of L2 cache).
----------------------------------------I am wondering if your OS is reporting CPU time correctly? Regarding the work you are returning I don't see why it should not be good, but you might be claiming and getting half the credits you deserve, unless the BOINC benchmark is "strange" too. |

1.43h is the CPU time, the time between start and finish (4.75h) of the task is always the longer bit of time. What is your cpu time % value under preferences? if this one is low (<50%) and/or you were running other cpu-intensive tasks (anti-virus scan, gaming etc), that might explain the difference. Or maybe you use a throttling device and your cpu's are running hot...
An explanation of the slow wingmen might be that they're either running super-old linux boxes or they're running a vm. |

herna,
----------------------------------------The problem with these CPU times is not relative to the wallclock time, it is that they are really very low for these kind of WUs. The CPU times that codes is reporting correspond to a 6 GHz processor, not to a 2.6 GHz one. |

Statistics Last Updated: 7/29/10 12:05:52 (UTC) [2 hour(s) ago] My last CEP2 wu completed and you can see 22 submitted for total 1 Day 9 Hr 21 Min, that would be less than 2 hours CPU time per wu. I suspect my client has under reported 4 to 5 times the actual CPU processed time. This has skewed the run time and credit for me as well as the adjusted credit granted to my wingmen. Sorry for any problems this may have caused others. Maybe the techs can adjust this by looking at the actual results submitted? The last WU before I manually updated showed for the properties of the WU 1.17 hours for CPU Time and 5 hours for Elapsed Time. My wingman shows 3.89 CPU hours: E200209_ 655_ A.21.C16H9NOS2Se.18.0.set1d06_ 0-- 619 Valid 7/28/10 18:04:54 7/29/10 10:59:31 1.17 18.3 / 39.1 <==== Me E200209_ 655_ A.21.C16H9NOS2Se.18.0.set1d06_ 1-- 619 Valid 7/28/10 18:04:40 7/29/10 00:53:58 3.89 59.8 / 39.1 I built this computer 2 to 3 years ago with OEM parts. It's not overclocked and has had various flavors of Linux, BSD, and Windows operating systems installed on it. I have not seen any type of problems to date. It currently is running Slackware Linux 13.1 x86 version, no anti-virus, no games, is strickly running WCG 24/7 at 100% CPU usage. Other than CEP2 wu's, all other WCG application wu's result in equal CPU and Elapsed time completed for the respective wu processed. So I suspect the problem is software related to CEP2 on my computer. I plan to reset the BIOS to factory default, reinstall Linux, install the BOINC agent from the WCG site, run some more wu's. Will then see if that makes a difference. [Edit 1 times, last edit by codes at Jul 29, 2010 3:05:39 PM] |
