To cut to the chase, David has admitted in the past that his agenda in all this nagging is for him, personally, to be assigned low candidates because they take less time, and there's a (slightly) greater probably that the lower candidates are prime.

David could, of course, simply sign up to GPU72 and have access to the (small number of) low candidates we hold for LL assignments. Ironically, David was actually the very first beta tester of this service...

But, at the end of the day, the truth is the next Mersenne Prime is probably somewhere up in the high 60Ms or even low 70Ms range; all the work below has to be done by someone(s). Those of us who TF are simply helping those who LL to not waste their valuable time if it can be avoided.[/QUOTE]
Those were the good ol' days.

I reserved a 45M exponent (TFed to 68) from Primenet, and put out a request for a GPU owner to TF it a few more bits with mfaktc (which Oliver had just announced). Among several offers, Eric Christenson (remember him?) promptly TFed it to 75.
I thanked him suitably and assured him that I would acknowledge his contribution should it turn out to be prime.
We engaged in much mutually instructive discussion of what the appropriate bit level might be.

I posted this anedote and requested a similar exponent. As Chris recalls correctly, he duly presented me with a 45M exponent TFed to 72 and P-1ed.

This simply goes to show that I am a veteran of this topic of discussion, and Chris ought to know better than he sees fit to let on.

But, by deduction, does that not also mean that I am also knowledgeable?

[QUOTE=VictordeHolland;354287]I don't see the relevance of this discussion, since we are ahead of the LL and DC wavefronts. If you don't like factoring to 74 bit, nobody is forcing you to do so. You can take expo's to 73 and somebody else might do 73 to 74. Besides, the TF GPUto72 is doing is 'extra', in other words, higher than CPUs efficiently can do.[/QUOTE]

This isn't so much a "GPU72 is forcing me to do something" as much as a "it's preventing me from doing something" issue. As I understand it, we've upped the amount of TF we are doing on the lower 60M's (the limit was 73 and is now 74) or some such and the result of all that is the exponents in the low 60M's still require some trial factoring work done on them.

David believes that there has been sufficient work done on them and he is bitter about the fact that he is now "forced" to work on larger exponents because the lower ones are being "held up" by GPU72 until the trial factoring has been done on them. It seems to personally hurt him that people are getting an exponent in the 66 million when they could be getting one in the 62 million. Note that all of my exponents right now (four of them) are in the ranges "being held up" so I'm not too sure what that's about.

I respect how keen and quick you are to learn the ropes around here.
(BTW here's a toast to Sir Ben Ainsley for rescuing the Yanks in the America's Cup. I suspect he might have given me a run for my money in my sailing prime.)

I find the whole GPUto72 ethos of personalizing everything [url=http://www.youtube.com/watch?v=IkEylc1-18M]tasteless[/url].

If and when I say "I" would prefer to do something or other, I usually mean the man on the Clapham omnibus.

Keep up the good work!

+1 :goodposting:

We however like David, we don't know why, but we in the same time are somehow tired of him requesting other people to work for him (like in "I only do LL, fcuk you TF-ers who do not TF my expos to 85 bits and P-1 them well, before they are assigned to me! (therefore increasing my chance to find a prime)"). (for newcomers, he used to sing this song some time ago, but he changed since he started not to like chalsall :smile:).

I never liked this kind of people, and that is the reason I don't like curtisc to much too. But don't take it personally, I am just an old and envious guy.

David is upset that he can't get lower expos to LL (and increasing his chance to find a prime even more), but in the same time he is ranting about gpu72 hoarding low exponents and assign them preferentially. Who stops him to became a part of gpu72 team and get low exponents from the pool? He even won't need to be a part of the team, just adjust the proxy in p95. I tell you what stops him, it is his personal self-pride.

Statistically, I personally don't see any proof of the fact that gpu72 is slowing GIMPS down. Contrarily. But what David doesn't understand, the world we used to live in is changing, we are too old for it now. Years ago we did not have cars, mobile phones, strong computers. We used to walk more, talk to persons face to face, compute with the pencil, and LL exponents of 20M. Now, the last is not possible anymore. Somebody else did it, we have to live harder now, driving to our jobs, having hard time to learn how to use iphones and gps-es, and LL-ing 60M exponents...

Can you make it 3D so we can see the exponent ranges by age also? Kinda like your range weekly progress videos are setup?

I could.

But, can't you do that in your head? :smile:

Well sure, but then I don't have a picture to look at :) Plus, as I get older I get distracted easily. I need something to help me focus better.

LOL... OK, I gave it a try, and I think you'll agree it makes the information harder (and sometimes impossible) to interpret than a standard stacked 2D bar graph....

Personally like it, but either way. If you can make it a 2D/3D option, cool. Otherwise, thanks for trying :smile:

The Makes Sense[SUP]TM[/SUP] assignments I've been grabbing for TF via GPU72.com have been exclusively 73 to 74 in the low 60's range (consistently going up as we do them; in the upper 63M right now). How long should it be before it turns back into 71 (or something) to 74?
