Also I have just noticed this on my running tasks: Minimum Quorum: 1 So no protection against false/fake results? That cannot possible end well. Three out of the current four WCG projects use a Quorum of 1. Where have you been?

Rest assured, there is heavy validation protection against falsified results. Each trickle is tested and if not OK, the hosts gets an abort instruction and any further part of the result by that host for that result is ditched. There are two terms in the progression of reported trickles: 1) Soft Stop, if a result is not processed quick enough 2) Hard Stop, if anything is awry with any trickle received.

Yup, compulsive drivel. It's called OCD. 
In 1969 I took an oath to defend and protect the U S Constitution against all enemies, both foreign and Domestic. There was no expiration date.

Three out of the current four WCG projects use a Quorum of 1. Where have you been? Only for devices that are shown to be worthy. I had two identical machines and one was just horrible with AD Vina tasks; 90% would fail verification. So it was always a quorum of 2 and I quit running FAAH on it. It was a waste of resources since a WU took three machines where 1 could do it. It runs MCM1, CEP2 and did UGM just fine. |

I'd have to agree, I have a lot of cores now running faah2 high priority and the math doesn't work- they're not going to finish on time.

?cause some1 hasn't do d math correct, now a 3 tasks on a dual-core machine will not get crunched by d today! so, what's going on guys? fix this!

What's going on is that it doesn't matter to the WCG that the WUs aren't finishing. The WU will not be resent. Instead a new WU will be sent that starts where the old one left off. No work is wasted. No work is duplicated. The science moves along faster. Everyone gets credit for the work they accomplished, even if the WU did not finish.

Not finishing is one thing, not even starting is another. BOINC has been very slow to learn estimated run times. Realize this is beyond WCGs control. Caches should probably be reduced to 2 days or less.

Fact: At WCG the client v7 does -NOT- learn about estimated run-times i.e. will not adjust them based on client specific actual runtimes. They are fully controlled and adjusted by the WCG scheduler system with each new assignment, based on server current validated runtime averages.
----------------------------------------deltavee has his explanation right on the button. It's irrelevant whether you complete part or whole of an assignment. If not completing a percent or whole by the deadline minus N hours, the uncompleted part is packaged into a follow-on task and the slow boat machine gets a cut-off instruction. This ensures the pace of progression from step 1 to step 3 million [or however many the scientists decide on], stays on track. That track is currently a theoretical -maximum- of ~120 days long to get to step 3 million. Practically/Statistically it will likely be sooner as when my host receives and returns 100K steps within 24 hours [which it does], this gains 3 days on the timeline. If then followed by a straggler that does not do anything by say day 4, the sequence at that point in time is still on schedule. [Edit 1 times, last edit by SekeRob* at Oct 5, 2015 2:50:08 PM] |
