Folding Forum

Hello,my name is Eric I live in Holland(Netherlands)and I`m new to F@H.
When I r-click the F@H "image" in my task-bar and select DISPLAY I see a protein molecule in different colours.
Does this image change as the program develops ? Can I see what the different colours represent in the molecule ?
And it shows around 250 to 300 with a max. of about 1000 "iter/sec",what does that mean ?
It might be a stupid question to a lot of people on this forum but as I said I`m new and would really love to know !

Thanks;Eric.

PS;Excuse my English,I`m Dutch.

Welcome to the forum Eric.

You may want to specify if you are using the F@H GPU Client (Nvidia or ATI) or the F@H uniprocessor Client? The viewer for all three are different.

Initially, when I used the Nvidia GPU Viewer, the image does change slightly.

I don't think that there is a feature that allows a colour coded key for the representation of the different molecules in that protein.

For the Nvidia Viewer, I would get two values. The first was 100ns/day and the second was 250/1000 which (if I am not mistaken) is the progress of the Work Unit (the protein that you are folding).

It is recommended that you don't use the viewer as it is known to be unstable which can cause the F@H program to crash. Also using the viewer will use up the valuable CPU/GPU resources so you will be slowing down the progress of the WU. The best viewer is the one that the PS3 uses if you are interested in it.

Hope this helps you.

Thanks for your quick reply.
My video card is a ATI Radeon HD 4800 series.And I run a Intell dual-core 2.66Ghz processor.
I have a soft-/hardware studio on my computer and it`s not running all the time,so I thought why not do something good with it when it`s not in use.I`ve allways had an interrest in biology,physics,mathematics and stuff like that so I thought,after a tip from a friend,why not install F@H.
I hope that by telling you my videocard you can find out what I`m looking at.(I don`t know how to find out what my viewer is).I wish you all the best from Holland,greetings:Eric.

P.S.:I`ll close my viewer when not in use and only use it very short when I need too.But if there is no legend(I hope it`s called that way)for the colours in the protein-molecule why colour them?(I can see different colours in the protein representation).

AGAIN;Excuse my English !

Hopefully you have downloaded the F@H for ATI GPU from Stanford's Website. The image below is specific to ATI Viewer

Name - The WUs name which is a protein
Core - F@H uses different core to process different WUs
Progress - Steps completed/Total Steps
Performance - Number of steps it can calculate per second
Time Left - With the current performance, how much time is left to successfully complete the WU

The Nvidia Viewer has different a layout and if you are interested, here's the link (http://www.legitreviews.com/article/726/18/) The article is old but they have described some terminologies. Although the fact remains the same that Nvidia GPUs are 1.5 - 2 times faster than their ATI counterpart.

I just assumed that the colours were just put in to make it similar to the PS3 viewer so that people can set it as a screen saver. Unfortunately, that's not the case. I have read somewhere that you can rotate the screen layout by using F1 - F8 keys but be careful as it can crash the viewer.

BTW you English is good enough for all of us to understand

Also, it is not recommended to use the viewer to monitor performance. It uses a lot of resources to display the protein that are no longer available for processing, and the iter/sec is not a good indicator of performance as it varies from WU to WU and it's affected by the viewer itself.

We all use PPD (points per day) to measure performance here and the general advice is to keep the viewer closed to maximize FAH performance. This value can be computed automatically by third party monitoring program (Fahmon, HFM.NET, FahSpy), or calculated by hand.

See the FAQ for an explanation of the colours used:

I think this applies to the CPU viewer, the GPU viewer uses the same colour scheme except that heavy atoms will be purple, and there will not be any coloured yellow.
