Hi together,

I'm a volunteer processing jobs for this fine project. But I want to get Credits as much as possible to move up to the best of all --- as possible ;-)- it's just a game, but I'm participating.

If Milkiway design it's jobs to use n-cores, they have to spent n-Credits per second AND core and not only per computing time or I will cancel my collaboration in this project!

What plans Milkiway to deal credits fair?

Regards,
Klaus

Boinc is a funky program as far as credits go, the standard is called 'Boinc new' and is supposed to give the exact same amount of credits for each and every project, but since that doesn't fit with every projects goals some projects have opted to modify the amount they give slightly. Some projects give a fixed amount per workunit no matter how long it takes, while other projects try to base it more on how much effort is put forth by the hardware.

I have a 6 core cpu machines, using only 5 cpu cores, and am getting this:
1,127.30 4,702.98 44.12 MilkyWay@Home N-Body Simulation v1.38 (mt)

While your 4 core cpu machine is getting this:
1,344.15 4,535.05 32.32 MilkyWay@Home N-Body Simulation v1.38 (mt)

My pc put more resources towards the unit so got more credits for it, but other then that they are similar.

As for the regular, or modified fit units, I am seeing this:
10,247.63 10,228.61 213.76 Milkyway@Home Separation (Modified Fit) v1.28

While you are seeing this:
10,695.39 9,688.81 pending Milkyway@Home Separation (Modified Fit) v1.28

Your 'wingman', as it's called, hasn't finished their unit yet so your credits haven't been granted yet, but their is no reason to think you won't also get 213.76 credits for those units, at least at this point.

IOW you are getting about the same amount of credits as everyone else here. If you really want to move up in the standings and get lots of credits you will need to spend tons of money and buy yourself a gpu, and the resulting hardware to support it, ie probably a new bigger power supply. You can get a 7970 AMD gpu for around $250 US, but since you don't have a fancy gpu now you will probably also need a new 750 watt or bigger power supply at around another $100 US or more. Chasing credits is not friendly to the wallet AT ALL, my electric bill alone is in the $600+ US PER MONTH range!!

Hi!

I've found your message because I also have a credit problem with Milkyway@home. I've been taking tasks for this project for some months but since a few week, I'm getting much less credits for each task. The time for each task is way under evaluated. It takes about 100 hours for a task that is evaluated for 25 hours. I haven't changed my computer and I don't have this problem for my other projects.

I don't run boinc for credits but I also think it's not fair, especially for the other projects ( I need to take much more milky way tasks to get the same amount of credits than another project. I'm also thinking about cncelling my collaboration.

You are also running Malaria and at least have been running ClimatePrediction on your pc too, this means each project has to share the available resources slowing down the crunching time.

Another thing could be that you are physically using your pc more often and the settings are set to not run Boinc when your pc is busy doing 'other' things. These are the default settings, so you didn't set them that way on your own. 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.

I have a Credit Problem with my Bank account, but not with my Project Milky Way. I crunch for it because I believe I do something which helps to understand our universe. My 5 cents :)

I personally think most of us crunch thinking we can make a difference in some way.

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.

I totally agree with everything you said! I am also a part of a Team, The Final Front Ear is the name of it, and while we are small we are still going strong. We too have alot of folks that joined and still contribute, but rarely visit the Team message boards.

I crunch to move up in the standings and to reach goals I have set for myself and my pc's. I have had as many as 23 computers on line at once, but am now down to 15 here at home, 2 of which do not crunch because one is a work computer my wife uses and the other one is my wifes and she just won't. If you ever get upto 20+ pc's you MUST use a Server as it is needed to take charge of all the little things normal pc's fight over when getting ip addresses etc! I am now 51st in the World of Boinc and still have a few more spots I can move up before I get to the really big hitters. I have already gotten 1 billion credits for one project and am very close to doing it for another project. I also have a personal goal of moving one project down my list of accomplishments for personal reasons. That means lots of pc's with cpu cores are needed to do that, and with lots of Boinc projects that goal is huge!

I fix friends pc's and they either give me their old parts or cash, or occasionally both, which I then use to put better cpu's and gpu's on line. I currently have two AMD 7970 gpu's online along with several AMD 5870's, a 6950, a 5770 and two Nvidia 560Ti's. I also have two more 7970 gpu's under the Christmas tree waiting for me. I had the cash and they were on sale, so it was a no brainer! With them I will get a second project to one billion credits and then focus on another project.
