1) Message boards : Number crunching : Calculating credits on n-core machines is not fair (Message 60516)
Posted 5 Dec 2013 by schizo1988
Boinc is designed to use SPARE time on your pc, not be the main reason the pc is running, as some of us have done.

Chasing credits is not friendly to the wallet AT ALL, my electric bill alone is in the $600+ US PER MONTH range!!

It takes about 100 hours for a task that is evaluated for 25 hours

I run 24/7 and my electric used to be super high and chasing credits is anything but friendly to the wallet. I was running an i7920 and a pair of GTX 295's with both the processor and the 4 video cards major over clocked, when in Jan 2010 I designed a separate system who's sole purpose was crunching i7920 and 3 ATI 5870's (top of line at the time and around $500 each), 1000W power supply, ASUS P6T6 WS Revolution motherboard, Corsair H50 CPU cooler, 6 g ram and a Cosmos S case, no operating system (I installed a oem version of Windows 7 ultimate 64 bit version), cost about $3000. I overclocked this system as well both CPU and GPU's

Highest World position ever 154 at 2010-06-21 and I was #2 in Canada but 2010 was the hottest year on record and cooling was a major problem and expense. GPU's changed everything as prior to their use the big numbers guy's ran farms of computers and all of a sudden a few hundred buck's and you were in the game.

The number of cores means less than the power of those cores as well

You may also need to as has been suggested to change your preferences. In the boinc manager under tools select computing preferences, things like computing allowed on batteries, when computer is in use, only after x min. idle etc.

If you select a running job and click on properties on the left it will give you an estimate of the number of GFLOPS to complete it.

I don't know much about the project asteroids@home but it has no GPU applications only CPU and might be better suited to a system without a GPU, not that I want anyone to leave milkyway.

I am currently running that 5870 system but minus one video card, now just 2
and I agree most of us crunch because we feel that we are able to contribute to the advancement of science and there are so many projects available it's easy to find one of interest and Some actually credit the cruncher with having made the discovery. I have a B.Sc. in Statistics, and an IQ of 160, I was born in 1960 so grew up during the Space Race, I took 2 Astronomy courses while at University, a full year which was general and a half year course on just the Solar System, planets and their moons, my neighbor during my teens had a 6" telescope, motorized to account for earths rotation, and my girlfriend from 1978-1988's older sister had a PhD from Yale in either Astronomy or Astrophysics I'm not sure. While she did go to Hawaii, her specialty was Radio-Astronomy and I know she worked at the one in Chile but mostly in Arizona using one of the large arrays in the desert, and frustratingly I have googled Dr. Janet Yamanaka but found nothing. In 2004 my brother was involved in a Canadian X Prize project the Canadian Arrow as part of the recovery dive team, it used a V2 based rocket but the capsule landed in the water, they did a unmanned capsule test in mid-august 2004. A helicopter took off from Toronto Island airport lifting the 770kg capsule to a height of 2400 meters (approx. 8,000 feet or 1.5 miles) before dropping it, and while it looked like the wind was going to cause it to land on the Island it managed to hit water, the chutes opened almost immediately and it fell at 6.7m/sec or 6 min. to splashdown.

mikey I couldn't help but notice that you run boinc on a whole lot of computers it's no wonder your bills are so high, in my case it has to produce significant enough results to warrant the cost, and I don't mean credits. I have always felt it is participating that is important, not the numbers you produce, being part of a team helps, and I don't mean just a country as you can belong to both. I belong to the PC Perspective Killer Frogs a team that is slowly dying as far as contributing members but our mascot is killer. I want to make clear I am not trying to entice members to leave a team, only looking for one's who do not currently belong to one.

2) Message boards : Number crunching : They are taking the server down tonight (Message 37938)

They have announced the server is to be taken down tonight and most of tomorrow in case you did not know
3) Message boards : Number crunching : Longer WU's for same Amount of Credit ??? (Message 37937)
Posted 2 Apr 2010 by schizo1988

My jobs seem to have returned to their old run times or very close, so need to run away yet. It may be about earning credits but it should not be all about it, people seem to jump from project to project as soon as they get a few hours of lower production, usually it works itself out and if the discrepancy is big the project usually makes an adjustment before long
4) Message boards : Number crunching : de_14_3s_free_5... shows no progress on 0.20 CPU client (Message 37369)
Posted 15 Mar 2010 by schizo1988

My 5970's read 0.000% then jump to 143% and count back to 100% but what I also noticed was it says .05 cpu required yet the cpu time is only a few seconds less than the total run time. My 295's take a long time but percentages progress as normal and the cpu time is a fraction of the total job time as usual
5) Message boards : Number crunching : more credits :) (Message 37019)
Posted 7 Mar 2010 by schizo1988
I hope these de_14's stay around for a while as they do crunch way faster than anything else, and you can score major credits quickly, as it appears they run about 5 times faster that the usual jobs, and that is on everything, my 295's, 5870 's and i7 920's.

On Thursday, I came within 30,000 of having my first 1 million credit day, so close, and not likely to happen again as they are now sending fewer of these really fast crunching jobs. I am actually glad in a way that they are not all this fast, as just one day of nothing but these jobs would be ridiculous, and sort of spoil things by granting too many credits, as I would end up being able to earn more than 4 million credits/day. CPU's are no longer able to produce numbers that make my over-clocking them even seem worth anymore and even doing it to my GPU's is becoming too much trouble as they tend to run hot even at stock speeds and keeping everything not only cool but quiet, can take a lot of work and extra expense for just small increase.

While Milkyway is great for GPU's it is not that great for CPU's, does anyone know of a good CPU project.
6) Message boards : Number crunching : All of a sudden I'm getting work (Message 21464)
Posted 7 May 2009 by schizo1988
After being unable to get much work and in fact being totally unable on one of my machines all of a sudden I seem to be able to get as much as I can handle, always have WU's available on all 3 of my systems. I don't have a ATI card and I had heard they were burning threw
most of the WU's. Are the jobs they get larger, because even my slowest system doesn't take much time, if I could use my pair of 295's it seems they would take only minutes. Hopefully CUDA will become usable on this site soon, currently while GPU's seem to be able to do more per dollar than CPU's, the apps that can use them, either brand is horribly limited. If a site can they should focus on adding this capability, because there are lot's of powerful systems coming on line at the moment hungry to do some crunching. While the CPU farmer are not too pleased with the credits people are racking up so quickly, I have notice lots of them starting to arm their farms, mostly with 260's on GPUgrid.net, they have 10 computers, meaning most had 20 PCI Express slots they can fill. I would be a bit pissed myself but it has meant more people can afford to do distributed computing and feel they are doing some significant science, for under $3000, based on my weekly and monthly results, I'm No. 2 in Canada, but more importantly I feel I can produce enough data from my crunching to maybe make a real contribution, as even my overclocked Q6600 only generated 5 or 6 thousand points a day depending on the app, my new system does more like 95,000/day. The guy from Mexico who has 10 computers all with 16 core CPU's and Dual GTX 295's in every one of them will in time eventually hit a Rac of 1,000,000/day.
