Re: Mapping Cancer Markers - Crunching Chart

Hey Sarge,
Wanna take a punt on how much your estimates will change once there is an influx of folks that currently run FightAIDS@Home?

The subject came up on our team and there was this thought from Mumak:

Now that FAAH ends soon, I believe a significant amount of power (a lot of machines running all projects using default settings) will switch to other projects: OET1 (which is run at low priority, so we can't expect a large gain), CEP2 (which is a special feed, so again no large gain expected), UGM and MCM


Unless the priority of OET1 is changed then 50% of those currently engaged on FA@H seem likely to move to MCM (perhaps automatically if on default settings)

Yes, I would like to speculate. Give me a little time to think about it and I will offer my opinion.
Cheers


OK, I thought about it, but there are a lot of variables to consider. If the average WU size stays about 5 hours and if MCM1 captures 60% of the crunching power now devoted to FAAH and if FAAH ends as scheduled on June 4 and then tails off over the next two weeks, the additional crunching power should move the end date up to the last week in August to the first week in September. There are a lot of "if's" here so this can hardly be classified as even the wildest speculation. Pure alchemy at best.

Cheers

Re: Mapping Cancer Markers - Crunching Chart

Your numbers make some sense Sarge but I shall be a little more optimistic because when entering similar numbers but obviously making dissimilar assumptions, the eye of toad method with the crystal ball gave me September 27th

Re: Mapping Cancer Markers - Crunching Chart

There is one big issue with those assumptions.

The scope of MCM Phase 1 has changed. Originally it was to be 17,500 WU sets that covered, lung, prostate, breast and one other cancer. We are still on the lung portion and they are now taking what was previously returned to generate new more focused WU sets. See: http://www.worldcommunitygrid.org/about_us/viewNewsArticle.do?articleId=419

So we don't even know about the other three cancers that were to be part of the original project. So we could go way beyond the original 17500 sets planned.

So, with many unknowns, we don't even know what percentage complete we are done and thus cannot even determine when the project might end. If the other three cancers are still planned, then even an increase in crunchers on this project may not end this project by the current estimated end date.

In the next week or so I'll be dropping out of this project and moving over to UGM. After around 280,000 WU's and 100 years, I'll let others get the badges they want on MCM1. I'll aim for a 100 year badge on UGM.

Please see mtsay's (one of the project scientists) post on May 13.
Hi Everyone: For the time being the number of batches is going to remain the same as the original estimate. We've now entered a phase where the future batches are based on results of current/past batches so it's challenging to predict with great accuracy the final endpoint. It may turn out that the project might run slightly shorter or longer than expected. We continue to try and normalize the run times as each set of batches from here on out is going to be slightly different from the preceding one. So, still Six Flags, but hopefully the kid's ride.

As of the date of that post they were not anticipating any change to the original 17500 batches. Obviously, if they change the number of batches or extend the project, the end date will change. As of now, I am basing all of my projections on this number which is the most recent and accurate information from source researchers. Given that this number has not changed, an assessment of the end date and a percentage complete can be estimated. As with any estimate, any change to the underlying assumptions will change the estimate. Thanks for thinking about this, I always appreciate feedback.
Cheers

Re: Mapping Cancer Markers - Crunching Chart

But it has to change or they are going to remove the other three forms of cancer from the project. The scientists planned on 17,500 that covered four forms of cancer. They have now taken the initial results of the first form (lung cancer) and are using those results to generate new batches. Let's say that originally (no one ever said how many batches were for lung cancer) it was 13,500, which leaves 4,000 batches for the other three forms. Now that they are using previous results to generate new batches:
1) What is the likelihood that there will be exactly 4,000?
2) That the other three forms won't be run?

If they decide to run the other three forms of cancer, then they will be higher than 17,500 batches. If they don't, they could be lower, or they could be higher.

So the real question is, are the other three forms of cancer going to be crunched?

Re: Mapping Cancer Markers - Crunching Chart

You are posing questions which only the researchers can answer. Until there is an indication from the researchers that the total number of batches has changed I am sticking with the figure they gave us:17,500.

Re: Mapping Cancer Markers - Crunching Chart

Glad the science moved into a O/I mode... interpret the output and refine new input. 'If' the other 3 targets are computed [asked before what would happen to those], then the learned from the first target will hopefully allow to zoom in much quicker. Clearly though with "For the time being the number of batches is going to remain the same as the original estimate.", progress computing will have to remain on seventeen.five, -with- an open end question mark. smile

I agree since no other number is available. This is more for others who think that MCM1 has plenty of work left and are concentrating on other badges. So it is more to tell them, don't assume that there will be work until Octoberish time frame. It could be October, it could be later, it could be soon. Especially since FAAH is coming to an end in the very near future. Once that occurs, I expect to see more computing on the other projects and time-lines being reduced until say another project comes along. I also expect the priority on one of the other projects to be bumped up as well.

Re: Mapping Cancer Markers - Crunching Chart

Looking at the Dashboard, it shows that we are crunching .19% of the remaining MCM WU per day. If you take the remaining 24.01% left, divide that by the .19 and then move the remaining 16% of total share from FA@H to MCM, you get 11 Sept 15 as the end date. The great thing about statistics: You can make them say anything. biggrin

The bigger question is what is going to happen to the 80.4% of the total power of WCG when there are no longer any Normal priority projects left? Without a new NORMAL project by then, it will be a cluster and we could go from 1.5M WU per day to 250K. and then again....not. crying laughing

possibly a real worry since we have not been informed of any new projects in the pipeline. devilish

Conjecture, Speculation, Assumption, Estimation, Irritation; the driving forces behind the WCG Forums cool

An outstanding question. My own answer is that I am fortunately able to crunch as many CEP2s at a time as I want, since I use ramdisks (or write-caches) to protect my SSDs. So I stopped all MCM and UGM work a few days ago and shifted the cores to CEP2. That will allow others to crunch them for a while longer. But that is only a drop of water in the ocean. What comes next is a good question; a GPU project would be nice.
