Re: Long computing times with short Due date?

@SekeRob* Thanks for your answer. I understand. My question was in relation to why you had only specified FAHB work not being sent if it could not be returned with in the 96 hour time frame as the other Is units have the same deadline.

Re: Long computing times with short Due date?

Ah, yes, those -ls- are 1M steps longer in the total chain, but per-job they are exactly the same, 100K steps.

Re: Long computing times with short Due date?

I test ran a few WU from this project even on a high end system I get like 15 hours runtime pretty much like CEP2 with long runs. I don't cache anyway since systems are full time.. my other system will get it done like 17-20 hours. once done my 5 year mission on OET is done.. then will be on this project.. if it trickles work units even that is fine.. systems do other stuff not needing much CPU at all.. :)

Re: Long computing times with short Due date?

This may not be in the correct section but I thought I would just place it here and get an answer:

How come I average 220 points per hour on OET and only average 137 points per hour for FAAH2.

I am strictly running OET for this reason because I am contributing more points per hour run and thereby furthering the research at a faster and more time effective manner.

Or are my assumptions just completely wrong? (The stats are 100% correct though)

I speculate that you are running some Linux variant. OET WU's are using Vina which runs extremely well on Linux. FAAH2 runs on BEDAM which runs completely differently. On my Linux systems any project running Vina yielded about twice the points of any other project, no matter the underlying software.

Re: Long computing times with short Due date?

I think the deadline should be extended... My Atom machines are the only ones that do not finish the task in time... :(

Re: Long computing times with short Due date?

Seen now, 76 days into the project generation #30, so that's how long the fastest target has been observed as completing. With a preprogrammed 4 days allowance, there's 120 days maximum on the shortest series, 160 days for the -ls- tasks, as they are 40 interdependent tasks long. If 120 respectively 160 days is the 'but we can't or want to wait any longer', there's the suggestion a little but of stretch in the deadline is present, but that's only an outside perspective where the techs are in that soundproof, windowless room where hardly ever anything escapes from.

Edit: To add, not wanting to plant a guilt-complex, but it may or may not have escaped you, we regularly see '[Run dry already' where fellow hosts are not getting work because the 'waiting on your result' is one of the factors it seems.

Edit2: And techs, because of this, members are buffering up, so once more, like the senator who does his weekly climate presentation in Congress, maybe time to set a ceiling, for that steadier flow. My Q6600 takes 33 to 35 hours to complete, so I'd be more than happy to have just a few to keep the cores busy when the previous completes.

Re: Long computing times with short Due date?

This project is a first of it's kind for us and we are utilizing some new procedures. We will continue to look at the data and consider tweaking settings where it makes sense. However with holiday breaks rapidly approaching I would not expect any big changes in the near term.

Thanks,

Other projects aren't reporting their usage until they finish the WU, but I've been seeing FAAH2 reporting that it has used some number of hours, but many more hours are still needed. The FAAH2 WU then keeps running, all 17 hours or whatever, but the credit given is only from that first report. I suspect this is why your average per computing hour is low, there's a chunk of wastage at the end. Like you, I've decided to stop running FAAH2 until somebody gets it straightened out. "status: No reply" with "CPU Time / Elapsed Time (hours): 1.63" just doesn't make enough sense to inspire confidence that FAAH2 isn't a waste of time.

I am a little unclear as to exactly which part of FAAH2 is giving you the headache. FAAH2 is designed to send a trickle message, a partial update of results if you will, every 10,000 steps. (There are 100,000 steps in each WU (work unit)). These are lengthy WU's, taking about 19 -20 hours to finish on one of my machines. I have seen instances of up to 35 hours reported by others. Partial credit is given at each trickle reporting. Even if you have not completed the entire 100,000 steps you are still being credited for the work done to the last trickle message you reported. The system is designed to start the next WU in the sequence from the last checkpoint reported by your WU. I see you have a silver badge for this project so you must have successfully completed a number of WU's for this project. If you could provide a few more details on the problem, someone may be able to offer better advice.
Cheers
