What efficiency are you getting with the tasks currently? As well as which WUs are you crunching? With that amount of threads, I would like to know how the writing to hdd is affecting your performance. Cheers Define efficiency? Time to do the WU? App 1.21 hours on the HCC WU, the HFCC work units vary greatly. I'm doing HCC and HFCC I was seeing issues on the Raptor with a 600s time to write but none now since I changed that to 1500s I do have a SSD that arrived yesterday and will try that. Just checked, number 11 host for the week and that isn't bad considering that during that timeframe I've had time off the project doing testing and also dealt with the HD issue. I'm pretty happy with the results so far, http://boincstats.com/en/stats/15/host/list/10/0/0 ![]() [Edit 2 times, last edit by Movieman at May 24, 2012 10:47:03 AM] |

1.21 isn't bad at all. By efficiency, I meant completed time vs wall time. Also, I would suspect a SSD would make a difference.

CPU time vs elapsed time. Because of the writing to disk as well as other things, the time it takes to complete the task, runtime, is usually different than the amount of time, in real time (on the clock). Can be found under properties of the running WU.

I do have a SSD that arrived yesterday and will try that. You may want to explore the idea of a "RAM cache". ASUS has a particular implementation of this idea. I don't know if the idea can be implemented in any other setup across the board (like "RAM disk" is), or if this is a special ASUS-only feature. See this clip.; |

Can be found under properties of the running WU. Ahh, yes, I remember this but don't remember exactly where to find the info... On the "ram cache" sounds like an excellent idea. I haven't installed the SSD yet, been sick this week and haven't done much at all. Moving the "time to write" to 1500 seconds has cured my intermittant lockups issue. ![]() |

Finally got the better part of a week straight on WCG and made the top ten..This is a tough group!!!!!!

That rig is Definately chewing through some wu's. Keep us updated on the performance.

Question for the brilliant here:
----------------------------------------Duration correction factor, what is it, how is this number figured and what effect does it have in the scoring? ![]() ![]() |

It's English I think, meaning Factor to Correct for the [estimated] Duration [of a task] ;>). WCG with server version 700 can throw this value away and do it's own estimate of how much work any device can do in the requested amount of time, but has not set it, because ... and that bit is not mine to share, but to say that something more advanced is looked for. Client 7.x would get told to ignore the DCF too with the <dont_use_dcf> flag [device owners have no control over]. Yours FTM receives work, but effectively has taken 1.2476 longer than originally estimated [the FPOPS that were put in the task header]. Since the tasks of WCG are quite variable [non-deterministic in nature], it's rather meaningless as the next task could be much shorter again. Rule is, DCF goes up fast [to protect against overcaching], and goes down slow.
