Anybody else have issues with the Omega drivers decreasing PPD? Went from around 70K on my 7970m+CPU to 45K.

 

[thebluebumblebee]

Have no idea what driver my 7770 is on. Most likely about a year old.

 

[agent00skid]

Yeah. My Radeon 7950 went down in points with Omega. Not sure if the current betas are better. Have changed clocks, and not sure where it would be on older drivers.

I seem to remember that there were a tread in the FAH support forum about it. Points going down was the concensus. Well I'm off again and since I still havn't taking my time to install Linux on my 970 rig it will be down again.

@mstenholm drink plenty of adult beverages before you try the Linux install.

Also, stay away from sharp objects, make sure any children are out of hearing range, and keep all hammers away from your PC.

Just a FYI:
I'm trying to get a diamond badge (my first) before the WCG FAAH project ends. I've thrown everything at it and then some. The "and then some" is an i3-3220T and MSI B75MA-G43. I'm currently running LinuxMint with a single 2GB stick of 1.65v DDR3-1600, WD 640GB Blue(3.5"), and powered by a Corsair VX550 (80+) PSU (from ~2006) and it's pulling 51-54 watts. Since I had it, I also used the Intel stock i-7 cooler. (don't know if the bigger fan affects the current draw, although I would expect it to be almost negligible) Have you seen the tiny cooler that they use for these low watt CPU's? "They're so cute."
When I win that GTX 980, it will go on this combo ....

Just wanted to say I finally got F@H TPU_remembers-Kreij going again this AM.
Long story short, last couple months just been ____________________ !!!!

 

[mx500torid]

758 People on the team and this week just 18 people showing points. Wheres the other 740?

 

[revin]

Look's like i'm keeping Dean's slot going again, gained 61 WU this week, but having issues.
Going to post over in the assistance thread................

 

[mx500torid]

Nice surprise

Core 21? hmm

 

[mstenholm]

Core 21? hmm

Linux looks even more tempting......wonder what six 970s would do. You know whom I'm trying to get back folding . OK I have been on/off for the past weeks but now I think I will be home for some time. Long enough to buy a SSD and install Linux and more importantly to get it to work.

Project 9704 (Core 21, GPU, Linux) moving to ADV
Postby mpharrigan » Thu May 14, 2015 1:46 am

Core 21 is the next generation of OpenMM-based GPU cores. It uses OpenMM 6.2.

This project studies the same system as p9752:

Sodium channels initiate signaling in neurons and other cells which go on to become sensations of pleasure and pain, as well as thoughts and feelings. Sodium channel malfunction has been linked with cardiac arrhythmia, epilepsy, and neuropathic pain. These projects simulate a whole voltage-gated sodium channel in a bi-lipid membrane based on crystal structures deduced only recently (2013). The channel is made up of four homologous domain which form a pore through the membrane. The "top" (extracellular) end of the pore selects for sodium ions only. The "bottom" (intracellular) region can be open or closed. Each pore domain is linked to a voltage-sensing domain, which causes the channel to open or close based on the electrical environment of the membrane. We aim to study the dynamics of transitions between the open and closed states mediated by the voltage sensing domains. Our experimental collaborators will probe sodium channel function through the use of natural toxins secreted by frogs in the Amazon rainforest. By combining theory and experiment, we can propose and test derivatives of these toxins which have positive therapeutic effects.

Runs: 245
Clones: 20
Gens: 781
Base credit: 9000
Timeout: 1 day
Deadline: 5 days
Number of atoms: ~175k
OS: Linux only (for now)

This project is constrained to run on systems with CPU RAM > 2000 MiB. While most compute happens on the GPU, general bookkeeping is managed by the CPU and CPU RAM. This large project uses a noteworthy amount of CPU RAM. There is no constraint on amount of GPU RAM. The GPU RAM used by this project is in line with most FAH GPU projects.

This project is Linux only for now. 32-bit Windows can only address 2 GB of (CPU) RAM. We're actively working on a 64-bit windows version of core 21, which will be able to run this project.

Happy folding!

I knew that it was there and did see some other numbers from when it was beta. It was just nice to see that the 970s did so good on what I assume is the final points adjustment before releasing it to the public.

 

[revin]

Now THIS is more like it !! 95k+

What did happen to Buck?

I have no idea what happened to @BUCK NASTY , maybe summer?

News (a little old, from May 7, 2014) for AMD GPU users:

We’re excited to announce that AMD has recently updated their GPU drivers from version 13.x series to 14.x series. Version 14.x includes updated OpenCL code that helps Folding@home run faster on GPUs (using fahcore_17). This results in a 5-10% improvement in performance. This should result in more points for some of the AMD GPU users. The 14.4 drivers are available both for Windows and Linux.

@mstenholm drink plenty of adult beverages before you try the Linux install.

Do I really need Linux - a 9112 gave me 316,323 PPD and a 9120 did 308,883 (both on my 970s). Clock was around 1500 MHz on my 4.4 GHz 4970. Newest drivers. They are more power hungry then the 9201s (+20W) but at 265k PPD = 2120 PPD/W versus 2140 PPD/W the points "cost" more or less the same.

Updated chart https://docs.google.com/spreadsheets/d/1W-PlatA9CgOOTA3qcvTxhFm_YoedvoHmXHNgZqczY4g/edit#gid=0

Edit: A 9104 (also core_18) is now at 315k PPD.

 

[NastyHabits]

In case any of you notice a lack of production from me, I'm away for a few weeks. I'll be back folding on June 16h.

Do I really need Linux

Running to Linux has actually been running away from core_15 WU's, although the new core_21 is only on Linux at this time. (which is actually really weird)
DC seems to be moving towards Linux, but I wonder if W10 is going to change that. Basically, anyone who wants a license can get one, so that removes one reason to go Linux. Secondly, Microsoft has closed the performance gap between Windows and Linux. So why deal with the idiosyncrasies of Linux that might get you 5-10%?

Sure the core_15 was the killer but they are rare. I got one and it died . OK I left my rig off during night time for the same reason. The 14.10 iso is ready. I will start out easy with my 2520 laptop running WCG. W10
