I too noticed the different points in other BOINC projects. I used to crunch SETI, Milkyway, Climateprediction, and Rosetta to name a few. When my wife got breast cancer, it was such a helpless feeling, being able to do little but research and support her, weather her storms, and encourage her. When I found WCG, which at the time was running Help Conquer Cancer and Help Fight Childhood Cancer, I dropped all my other projects and began to crunch only here. It gave me a feeling of being able to do something, no matter how small. I feel the the projects here have merit and while I do like to track my numbers and collect badges, the main goal is to contribute. I have 10 years and 1 day on Mapping Cancer Markers which netted me 9.9 million points, while my 10 years and 105 days on Fight Aids has resulted in only 4.9 million points. Who gives a damn in the long run? IMHO, if one is here with the main goal of collecting points, then one is here for the wrong reasons. It fries me to hear people complain about such petty b.s. The world is an imperfect place but we're all going to leave it in the end... I'm sure this isn't what you wanted to hear, but you brought it up. Just chalk this up to another 'pointless reply.' Mike same thing led me here, with cancer of my Grandma...but I lost her 22y ago! & she has practically raised me as a child...so when she died died, a whole World collapsed...& I was in a depression 4 a long time, just not showing it! it lead me to UD grid.org...which lead me here! & here I'm still... though, I do pursue badges right now...it's just a completion right now, by helping d World 2 B a better place! so they also have a purpose...imagine there r some individuals which do over 1TF in a 1d - awesome results! we need those people also... d way I look @ this is similar to #WCG staff: "Grateful 4 all the contributions 2 d Science!" ![]() |

The credit question is not that simple.
----------------------------------------I operated during the last 10 months two similar hosts: - Identical main boards with 4 GB RAM and identical BIOS setting - Athlon II x4 640 The only difference was the operating system: - Windows XP Pro (x32) - Ubuntu 14.04 LTS x64 The both hosts were dedicated to WCG only, running 24/7. The Windows-based host earned daily about 2'000 credits until the Ubuntu-based host earned about 4'000. I noticed that there is some differences between OET1 and UGM1; with around 10 CPU years contribution: - OET1: 23 Millions - UGM1: 18 Millions However, until last July, 4 hosts were dedicated to OET1 : 3 Ubuntu (Athlon II x4, Phenom II x6) and 1 WinXP (Athlon II x4). At the other side UGM1 has been mostly computed by a Win7 Pro x64 host (i7 4770K). Regarding the poor efficiency of Windows based hosts. I cannot conclude that UGM1 is less crediting than OET1, even if there is 5 Millions credits difference after 10 CPU years. Cheers, Yves --- PS: Phenom II x6, 1090T: around 6'000 daily credit (6 threads) Intel i7 4770K: around 5'250 daily credits (8 threads) |

I noticed an imbalance between OET and UGM a few weeks ago. It looked like UGM was granting twice as many points per cpu hour so I switched all of my machines over to do UGM exclusively.
----------------------------------------But that seems to have been transient. I don't normally look at stats for individual work units but when it looked like I wasn't producing as much as I had been, I looked at validated results and discovered the discrepancy. Now, a couple of weeks later, I had a problem with one of my servers and needed to reinstall boinc. Since I'd been getting a no work message, I set up another profile just for that machine to grab OET and UGM again. After about a day, I checked the results status to see how things were going and noticed that both projects now seem to be producing the same number of points per hour. UGM seems to have a slight advantage still but certainly not double. For all of the people that like to downplay the significance of points, you should rethink that position. Whether you like it not this is an important motivator for a lot of users. And you should welcome that fact because even if a person has the supposedly shallow and superficial motivation of accumulating points, they are still contributing to the important research being done. This is like the controversy over the Ripple giveaway. Everyone seemed to get their panties in a twist over all of the new people joining with non-altruist motivations but the fact remained that we actually managed to turn around our multi-year decline in active membership. I often get the feeling that everyone here would rather see us get back to 2007 membership levels. I'd also point out that points are supposed to be an indication of work done. That's how I know when something is amiss with one of my rigs - when I see an uncharacteristic drop in points. So it's important that the allocation of points be fair - first because it tells you how much work you're doing both within and across projects and second because it's such an important animus for so many members. ![]() ![]() |

Hi KLiK,
----------------------------------------my post was only for information purpose. I am fully aware how to manage my hosts for the most efficient contribution. My intention was to mention that the question related to effective granted credits is not only a question of which project allows to earn more credits. Many factors impact the final level of granted credits. Yves |

KerSamson,
Just to get the record straight for all the 'Readers', the AD VINA based science performs about 60% faster on Linux [and Mac being a *nix variation], or from the perspective of Linux, AD VINA on Windows is twice as slow. It's always done this as did HCC [speculation on the Integer heaviness being A reason, the available *nix libs much more optimized, the Dhrystone benchmark test of the client being the corroborative to this observation]. Reading your post, this is the key reason why you see such big credit differences from science to science. Taking Windows as reference, the issue of this thread is that on this same platform, doing ~90% of all the crunching, there's substantial inconsistency in credit. This gets amplified on Linux/Mac 'just from a 'on the surface' view by out performance of sciences with AD Vina'. At some point I sat down and proofed how I could double the credit on the same platform, by being strategic in micromanaging. The recipe is mine, same as the Coca Cola one stays under wraps ;>) |

Hi SekeRob,
----------------------------------------my comment was primarily proposed for de-emphasising the general feeling that some projects would be contributor-friendlier than others. Since the world is not perfect and since the computer world is definitively not pefect, I was only trying to demonstrate that the credit question is not that simple and it is not only a question of "project fairness". Some months ago, you mentioned that operating Linux in a VM for crunching purposes could be more efficient than to crunch natively (bare-metal installation) on a Windows host. Even if I miss some available time, I would like to benchmark such a configuration. Cheers, Yves |
