Well alright then. If you go on vacation, don't forget to mention to someone about monitoring things. Noted.

Based on ProDigit@EVGA suggestions my 'summer' folder is a dual 2060 super.  I often see this system >3M PPD.  With a 75% power cap.  Total system power draw is a very modest 370 watts.  GPUs in the low 60Cs. Older Q87 mobo, i7-4770k cpu.  The skeleton chassis was scavenged from an old tower system, it's mostly repurposed gear.  Besides the GPUs, the only new stuff is case fans & heatsink, and I really didn't need the heatsink as I don't do CPU folding as it isn't power efficient.  PPD production is close to a 2080Ti and if you can get OpenBox GPUs, about 1/2 the cost!

We have now passed the 10 Billion point mark with 18 of us now passing the 100 Million mark with 2 more close to it as well. Keep up the great work everyone. We can be sure this isn't going to just go way like we would all like.

Hey folks, having a problem here.

I am running a Lenovo ThinkStation C30, two Xeon Processors, 64 GB of RAM.  Not running a GPU for folding.  OS is Fedora Linux running a KDE desktop.  I have 6.5 TB of Hard Drive.  The OS runs on a 256 m.2 SATA card on the motherboard.

The problem...     FAH a7 Client cycles about once every minute or two, runs at 100% and then stops after twenty seconds or less.  Did all my updates, rebooted the machine, and the problem persists.  Moreover, this machine has been working without an issue for three weeks.  I only finished building three weeks ago.  And on top of all this the FAH Control wont run except through a browser.  I am running the 14524 Covid 19 project.

I am running two other Linux machines with similar, less powerful setups and a Win10 machine.

Ran out of ideas.  Any help is appreciated.

I believe there was a post on the fha fourm that will address the issue if i remember correctly

I would suggest posting that log on the fourm for fah the guys there can help you a ton with it. It does look like a setting in linux that might be a issue but not 100% sure. I don't think a wu can be flushed out but it will time out and fail. you might be also able to look at the log file and check a gromacs settings against the url they have in the log http://www.gromacs.org/Documentation/Errors

@MightyMayfield nicely done cracking the 400 mark.

Thank you! MC45 is also about to cross into 1000 territory, too! I'm grateful for their and everyone's continued contributions. I never imagined a simple request of mine might lead to an entire army of machines sciencing their way towards a better future. I do wish hardware was a bit easier to get these days though. Large power supplies are getting slim pickings for folding rigs.

We really need a way to keep people motivated in this.

The summer months will be difficult as most people will be paying more than double for the cost to run gear because of the cost to extract the heat generated. Of course no HVAC system is near 100% efficient, so summer PPDs can strain budgets & emotional commitments to a cause. One of the reasons I posted above about trimming watts expended and selecting gear with higher PPD/watt.
So, one approach would be to encourage people to return in the cooler months.  Folding on cooler days or evening hours when power might be cheaper too.

I don't know if any kind of contest would motivate me to do anything more than I'm already doing. Which is not much, as after two months my points totals are a little over two million and my work units completed a little over 400. My off-the-shelf machine is simply not that powerful. I'm basically just donating spare cycles when I'm not seriously using it (running the folder at full power drags down anything involving rapid screen updates). What I find more motivating is seeing actual results coming out of all these contributions people are making. How many work units does it take to complete an average project? 'Cause I have a feeling that I'm seeing the same project numbers that I saw at the start. Hundreds of millions of work units completed and apparently not done yet? That's discouraging.

Hi teamtempest, the amount of WU in a project can vary greatly depending on the type of research it is. I would advise looking at the scientific papers published by the FAH team if you would like to see what ends up of the computational power! Some of them are quite interesting reads. They can take months to be peer reviewed though, so many of the covid papers are going to be quite some time out still. Those can be seen at Stanford's page before public release.

@cine_chris just to point one thing out I did refer to my local MC store not to everyone else.

Wow, triple post and a day later. Ouch.

@kmiller922
Of the Top50 Folding teams MicroCenter was 7th for member retention.  Thinking it might be interesting to see how other teams retain folks.

Awesome!  Good job cine_chris
