If I have a quad core machine then I should set my cache to: cache in days = 52 WU's needed * 7 / 24 / 4 cores -> 3.8 days I am surprised at the assumption that a quad machine working for 24 hr will only get 1 day of time credit. My experience is that I get 4 days of credit. Farpung, the client setting will multiply the set days with the number of cores that BOINC is allowed to use. 3.8 days will thus result in ~15 core days of work.

I am surprised at the assumption that a quad machine working for 24 hr will only get 1 day of time credit. My experience is that I get 4 days of credit. Four days over 24 hours is not right either. I have two duo cores and one quad core (for a total of 8), and I have been averaging about 6 days in a 24 hour period. Since I thought I would need more power to reach my goal, I went to Advanced -> Preferences to change my CPU usage on one of the machines to 95% and to 88% on the other two. If it does not overuse the system, I may want to increase CPU usage to 95% on the quad core. I noticed the length of time to complete a W/U is still 7 hours, but I got 8 days of time yesterday (probably some from jobs that completed for the previous day). That is the largest amount of time I have ever gotten in a single day. [Edit 2 times, last edit by Former Member at Mar 3, 2010 12:02:29 AM] |

with rice, will always be 7 hrs, reguardless of cpu, more cpu=more positions completed=more points.

And so another thread derailed. Yup, and I contributed to the derailment with a truly stupid post. Thanks for your original point. I learned from it. But now that we know, what else is there to say? [Edit 1 times, last edit by Former Member at Mar 3, 2010 5:55:06 AM] |

If you are close to that edge, PLZ do not over-cache. User-Aborted results are NOT REISSUED to the pool for this project if 18 have already been validated or the validated plus "In Progress" will make up that 18 anticipated valid results. The 19th copy is only re-issued again if not enough seeds have been computed in a batch... ~120,000 needed! Your fellow badge-upgrade goalers will thank you for the consideration! Thanks for the info Sek. I normally do not cache WUs, but I am so close to my first-ever blue badge I did not want to miss by a few WUs. I created a little spreadsheet to compute how many days and results have left to go (7 calendar days). I had planned to decrease the cache daily until I hit my mark. I did not want to go over by much either since I have other badges to chase. I did not know that aborted results would not be re-issued, so I'll be extra careful. The only variable I hadn't been able to factor in accurately in the past was the hours waiting to be credited. Now that I have been caching, my completed jobs are validated immediately so I am assuming that everything gets picked up when the stats are updated. Your chart that predicts the completion dates of the active projects has been most helpful to me to strategically select which projects to run. If there was anyway to hone that projection for this project to get the number of days left or total number of available WUs I wouldn't be so anxious (or perhaps greedy). ![]() |

So yeah, aborted WU's are not reissued (to a point).
But why? I recall this is some sort of resolution thing, that once the min resolution is hit, then aborted WU's are not resent. But what is the gain of the max resolution? It seems that we are either crunching when we don't need to, or risking aborting crunches that need to happen but never will. Can we judge the seriousness here? |

There's 2 parts to user aborted in the specific RICE project case:
----------------------------------------1 - if at point of abort there are the minimum seeds, no reissue. 2 - if at point of abort there is a need to re-issue it only goes to the fast returners. Locks the > 4 day cachers out. I'll take them. The techs emphasized "we like to have them", again me underlining what the title of the thread expresses. Cutting it short here, max the available results for the last minute boarders including the bigger bufferers... badges are a mission too... to show you were there ;>)

You should also consider the amount of work in progress you already have. Go to My Grid -> Results Status and filter by:
Device Name: All Result Status: In Progress Project Name: Nutritious Rice for the World That will give you the number of WU's already in cache in all your devices. If you have several pages then: Number of WUs already in cache = ((number of pages - 1) x 15) + number of results in last page This number x 7 will give you the amount of hours in cache. Subtract this to the number of hours needed to achieve your goal to know exactly how much new work you still need. Easy, isn't it? ![]() |
