Welcome to FahCore 17

We are proud to announce that our latest GPU core, FahCore 17, was recently moved from beta to advanced testing, the last quality assurance step before a full release. As we previously mentioned, this core is a significant step for us. FahCore 17 is a complete overhaul from our previous GPU cores. It brings a cleaner and more streamlined codebase, new serialization mechanisms that allow us to set up diverse simulations, and improved stability. Its use of OpenCL has united our development, allowing the single core to run on both Nvidia and AMD cards, and theoretically any OpenCL-capable device. It is also our first GPU core to run natively in Linux, although we are only supporting Nvidia GPUs there for the time being as we wait for AMD's Linux drivers to mature a bit more. Overall, this core sets a strong foundation for the future of GPU core development.

On AMD cards, FahCore 17 is about 10 times faster than the old GPU cores, and on Nvidia it's about twice as fast. This is mainly due to its OpenMM 5.1 base, which contains many optimizations which deliver a significant speedup. One optimization in particular that we are waiting for is CUDA JIT, a just-in-time compiler that Nvidia may be introducing into its drivers in the coming future. Not only will this technology allow us to offer support for the CUDA platform with FahCore 17, but the JIT compiler is likely to deliver a massive speedup. For the time being, we continue to work at finding additional optimizations on our end. We have also successfully tested FahCore 17 with extremely large proteins (500,000+ atoms), which are on par with the ones used by "bigadv" CPU projects.

To run FahCore 17, you need a Fermi GPU or better and Windows or Linux, or a AMD HD5000 or better and Windows. It also currently requires proprietary drivers from these vendors. You can test FahCore 17 by adding the "client-type = advanced" setting into the extra core options in the V7 client, as in the Configuration FAQ. Another excellent resource is the GPU FAQ which describes why GPUs are so helpful to us.

We'd like to thank all the alpha testers on FreeNode's #fah IRC channel, as well as the beta testers on foldingforum.org, who have all helped us bring the core to this point!

Thank you!

"Finally time to install my new 780 - oh what's this, a new core?"
DÆNG!

Is this distribution between the 3770 and the 780 normal?

Cheers for the update 'Cuda340

@RoXQi3x
NVidia requires a core per GPU like AMD used to when running Core_17.

F@H does not respond well to running Max cores + some cores being busy on something else - can cause a radical drop in PPD

Set your SMP to 6 and you should get an increase in PPD on CPU and maybe GPU also.

oh.. and just How am I meant to catch you now huh??? LOL
I was looking forward to that too!

wow, nice PPD on that 780.

I have some problem related to this:
I use client v7.3.6 in Win7 x64, and when I try to run it with both "beta" and "advanced" flags for the GPU slot, one of them "falls off" - it does not appear in the "extra slot options" after I add it and click ok - only one of them appears.
Should i add them in a single dialog box with a comma or something, or I suppose to use only one of them?

 

[Janus67]

I think you only need advanced now.

error message

I open the Advanced Control for F@H.
Left click on the Configure button 4th from the left.
Left click the "Slots" tab.
Left click a cpu, then left click "edit", Go to "Extra slot Options, left click the "Add" button, then I type in "client" (without the quotes) in the top field, hit tab and type in "advanced" (without the quotes), then click save.

I get an error message:
On client "local" 127.0.0.1:36330: Option "client" does not exist.

Anyone know what I'm doing wrong?

I have two 780 cards I want to get folding at the most efficient rate. They are each running at about 35,000 PPD overclocked (cpu @1125 MHz, memory @1650 MHz). I'd like to see both of them running at over 100,000 PPD.
Running Windows 7 Professional.

Farwalker2u, write "client-type" instead of "client", that's the tag.

 

[Farwalker2u]

Thank you.

I put in "client-type" (no quotations no spaces), and it seems to have accepted it. I anticipate that the next wu I get the 780s will produce over 100,000 ppd.

EDIT:
It seems that the 780s are producing more now!


The GPU utilization is erratic. Note the picture below. One card is running between 50% and 100%. The other 780 is running between 89% and 100%. Also note the drop in PPD to 214K.

Yes they do a bit don't they lol

I like it, if they were mine I would feel like I could watch such numbers streaming out all day long
