Prime Grid Motivation
« on: October 16, 2011, 12:55:51 AM »

Hi there all you Prime Grid Crunchers,
I don't currently crunch prime grid, I also don't plan on crunching it. I've done a few hours trying to research the motivation of prime hunters and am wondering what the individual motivations of my fellow boinc@austrlia crunchers are.
I will also say that the reason that I don't think I will crunch on this one is that I don't see that it can contribute meaningfully to science.
This is meant to provoke discussion, I'm not trying to denigrate your choice in crunching. Just curious.

Different strokes I guess Chris.  The science is mathematics. My interest is that of an old crypto person albeit my time was before computers.  Is it useful science?  Perhaps so, perhaps not, that would depend on your point of view.  The project has gained the interest of mathematicians around the world.  Maybe it is just one of those "for interest" projects.
What it is though is a very well run, stable set and forget project, not hard on graphics cards or my ISP's monthly data limit.  In the pure numbers game it has helped our small team to stay within touch of the big BOINC crunchers.

The beauty of BOINC crunching is that there is a project for everyone.  I wish the medical projects would get into GPU processing but until they do prime hunting will have to do.

Thnak you for raising this subject Chris.  One of my pet hates is political correctness and that, I believe, is an evil that has robbed us of the freedom of speech.

Cheers Mate.

Good question Chris :thumbsup:

I wish the medical projects would get into GPU processing but until they do prime hunting will have to do.

This is probably the main reason I run Prime Grid. I have an ATI gpu so there are only a few projects available for me. I like Prime Grid but would rather run a medical type project if I had the option.

Hi all, whilst I don't crunch PrimeGrid, I do crunch for Collatz.
Motivation behind that is purely practical becuase I have ATI cards that dont support DP. That limits the choice of projects that are available.
Secondly, I wanted to choose a project that was stable and long-term.
By that, I prefer selecting projects that don't retire within a year and has long term viability.
To me, thats an inidication that a project needs lots of computing power.

I crunch Primegrid because I also have ATI cards and I am interested in Mathematical type projects.  I also crunch Collatz, and DNETC because I only have ATI GPU's except for one.  I also like the thought that when I find a new prime number it is recorded in an external register of Prime Numbers against my name. Remember it is only the llr work units that find new primes and there is no ATI application for llr.  Being the founder of the Team I attach to all the projects that the Team is crunching, usually when they are first created.
