Post:
If you\'re running 8 400Mhz machines and can afford to replace them with a single dual core 3-4Ghz cpu, then you\'ll be spending less on electricity with the single new system.

Contributing to Rosetta or Boinc projects in general shouldn\'t be limited to just those of us with faster machines. If the Carbon Dioxide produced from electrical production is considered a big deal - then encourage everyone to plant a few trees for every computer they use.

3) Message boards : Number crunching : Claimed/granted credit (Message 39070)
Posted 5 Apr 2007 by BennyRop
Post:
When I tested the granted credit ratio on AMD 64 cpus, P4s, and the Intel Core cpus - I remember the P4s as overclaiming, while the AMD 64s and Intel Core and Core2 cpus underclaiming. Changing the cpu mix will change the average ratio of the granted credit to the claimed credit on your machine.

As mentioned before, recent changes started giving the \"waiting for memory\" message. If you\'re running 24/7, you should be getting close to 86400 seconds * 7 per week per core. (604,800 seconds per week per core). If you\'re getting less seconds of work done per week than normal, then it\'s time to track down why you\'re losing more time than usual.

Some of the things I\'d ask are whether it\'s just AMD Windows users that are noticing a decline. I\'d look at my results, but my Rosetta system seems to be offline at the moment. :(

When the granted credit system was first changed, I was averaging a nice bonus; although a few months later, that bonus had decreased. If lots of users are noticing a recent decrease in the claimed/granted credit ratio - it could be because of the mix of cpus and OSes being used by the recent influx of new users. (Lots of Linux users would decrease the average.. and a major change in the intel/amd cpu could also be responsible - if this is a project wide issue.)

On the other hand, if it\'s just your machine, a change in anti virus software (Norton\'s bloatware) can cause a loss of cpu cycles. (I noticed a slight improvement switching to Panda Titanium). Virus/Trojan/Worm infections can also cause a loss of cpu cycles and system slow down.

Run through Spybot Search and Destroy, Adaware, and spywareblaster. Next, use TrojanHunter 4.6, Ewido which is now called AVG Anti Spyware 7.5. Then do a couple of online scans (www.bitdender.com, www.pandasoftware.com, www.trendmicro.com, etc.) That\'ll catch most of what\'s out there and help rule out malware.

The description of the ignore feature made it sound like someone on the ignore list would have to get positive ratings high enough to hit the emphasis rating to show up. But they show up at 0 for the default settings, which makes the setting - pointless.

My filter threshold is set to -25 (default) and greg\'s id is now in my ignore list. The message with a filter setting of 0 shows up with no problem, but the message that has a filter setting of -1 says that the message is hidden because the poster is being ignored.

I\'m using firefox 2.0; but this isn\'t the effect I\'d expect from the filtering/ignoring. (Time to empty out my ignore list and set my filter threshold back to where I had it.)

With the length of time it took Mhouston over at F@H to get the client to the state they did on the nvidia chipsets, and then give up and get to work with the ATI chipsets - any reduction in the time to code the app would be a benefit. It\'d be interesting to see the Rosetta@Home client experimented with to see what can be run on a GPU, if that didn\'t detract from the crucial work being done on the cpu client.

Moving to different formats (GPU, PS3, Xbox, etc), optimizing the client for AMD&Intel, and coming up with new approaches that will improve the accuracy while reducing the workload (twice as accurate with half the cpu time) will all improve the efficiency of the project. Our helping attract and retain new crunchers will help improve the speed of the project, as well. :) Here\'s hoping for more staff to help with the client upgrades/ports/changes.

As for apologizing, I spent several years on an online game where I spent 6 months documenting a singular user\'s breaches of the Terms of Service. It took 6 months to get rid of the punk. They let him have chance after chance.. I heard people bragging about how they claimed they weren\'t familiar with english and didn\'t realize the slang they used was banned. So when I hear of people being banned for no reason I had reason to doubt that I was given the full story. The company that bought the game from the previous owners which I\'d worked with got upset with my pointing out that the new owner was caught lying publicly. I lost posting privileges on my second account when I demonstrated to the inept new staff how to properly respond to questions by the subscribers.

I\'ve seen both sides - but I find it hard to believe that a Boinc project would ban for posting a diplomatic message about a problem. If it\'s the same person that was posted about here, the message here was a link to discussion about the user\'s transgression and the solution used on another project. (Erase all points, and perhaps give no credit for the work being turned in for that account.) A member of the Rosetta team posted that they\'d zero-ed out his account, if I remember correctly.

Mind you, I didn\'t see any of the discussion on Predictor@Home, but if the project staff had requested that the conversation end and they banned those that broke that rule, then an apology should be a good start to getting your posting privileges back.

It doesn\'t sound like an approach that is going to get the results you were after. Writing an email to the developers of the project, calmly and diplomatically explaining the proof that the accused is doing inappropriate things, and then showing how similar people have been dealt with on other Boinc projects should allow it to be dealt with properly.

If you\'ve managed to get them to remove your posting privileges on their forums, then you need to calm down, step back, and diplomatically write them and probably apologize. (I listed all the failings a company made in dealing with my order - and the bum was so offended that he refused to do business with me ever again - so I\'m not perfect in the diplomacy department. :)

Post:
The Boinc benchmarks under Linux give results that are about 50% of the same hardware running the Boinc benchmarks for Windows.

The granted credit approach was Rosetta\'s attempt to even the playing field for AMD vs Intel, Linux vs OS X vs Windows. And while it\'s not perfect, it balances out over time. :)

Post:
We\'ve had a number of changes made to Rosetta thanks to our suggestions in the past. So they do watch our conversations on problems and suggested improvements and sometimes incorporate them into the Rosetta client. I.e. let us make a suggestion, watch others point out failings of that suggestion, and others come forward with suggestions to overcome the mentioned failings.

That\'s correct, Lucifiel. :) And if the WU doesn\'t make any progress for long enough, the Watchdog process will terminate it for you.

Post:
With 2 gigs of ram, you\'re not running into the problem of not enough ram to run two copies of Rosetta\'s larger WUs, and you had 171,000 seconds of work turned in on the 22nd, so both cpus are running full time (it should average out to around 160,800 seconds a day over the course of a week when 2 cores are in use.)

The cpu mix on the large jobs is different from the cpu mix on the smaller jobs and is causing the average to be a little lower than you\'re used to.

Why this project? I\'ve been involved in several life science DC projects, and after FindADrug finished, teammates moved here. The fact that Rosetta beat an earlier project I was running at predicting structures helped draw me here. Rosetta seems like one of the best places to be helping to develop code that can be used by projects dedicated to finding treatments/cures to the diseases that are personal to me. Plus.. there was a rumour that this was a great way to attract playful ladies of a licentious and salacious nature. *snicker*

My science background: I am not a molecular/chemical biologist, but did spend time in chemistry thinking up \"safe\" ways to make nitroglycerine using the local WWII bunkers, 55 gallon drums filled with water to dump the acid mix into if it began getting too hot. With the mishap(s) that happened due to black powder experiments, it\'s a good thing I never got ahold of the necessary acids. :) As a comp jock, it\'s much safer for me to help out others with my donated cpu cycles.

I take part in Rosetta (focusing on basic research, and our soon to be applied research on various ailments) as well as donating cpu cycles at Folding@Home which performs similar but different research.

The online communities and messages boards are an important part of the dc experience for me; although if the project leaders ignore us - we\'re likely to run off. I tried out a project for about 6 months and never could find the bragged about proof that it was creating results that were useful - while the project leader basically ignored us with one or 2 month departures.
One of the most fun parts of the DC experience for me was competition; having joined a team and finding ways to climb through the ranks of that team while helping the team climb against other teams. Running systems for a few more hours a day, or running an extra system to overtake the person above me - was addictive.

Back to the topic.. If seeing 1.xxx% until the first decoy is done is a problem for users that don\'t start the project by first reading through the FAQ, is it possible to display a counter of the steps involved in the WU? (Working on Step 2453 of an estimated 287,400 for first decoy, minute 12 of 10,800 Run Time preference)

Only more concise?

There was a suggestion by Angus or Nemesis to send the run time preference and have the server decide which WUs to send to the client, picking ones that will use less than the set run time.

When I suggested sending the system stats to the server and getting 4 hours of work, 8 hours of work, etc. it was explained that the Boinc client at the time didn\'t support sending information back. Does the latest Boinc client support such 2 way data transfer? And if so, how many people are still using older Boinc clients on this project?

Another possibility:

There\'s been comments about memory usage settings with the latest Boinc clients causing issues like this when two large memory WUs are downloaded.

Check the Use at most (% of memory) when Busy/Idle settings, the amount of ram in the system, and the amount of ram being used by the single Rosetta WU that is running.

Post:
The advantage of a gaming console like the PS3 is that when you write for it, you know the hardware. They\'re all identical. Any optimizations for the hardware (ram, video, cpu) on the PS3 will be applicable to all PS3s.

For GPU clients, we have two big names.. ATI and nVidia - with ranges of cards with different GPUs with different abilities and different amounts of ram present on the video cards.

If it was easy to write GPU clients, then F@H\'s nVidia client would be available - instead of their giving up and developing an ATI client first that\'s still in Beta. (And a pain to setup.. now thinking I\'ve got multiple video cards in a system I was Beta testing it on.)

We don\'t have optimized clients for the Intel cpus vs optimized clients for the AMD cpus here - and you\'d need a variety of clients optimized for the different brands and classes of GPUs to take advantage of the modern GPUs - or a general client that only takes advantage of the abilities of the lowest common denominator.
