It looks like I'll be passing woolly tonight. Finishing up on a 50,000 frame work unit. I'm curious if they throw me a bigger one.

What's the largest work unit (in frames) out their?

*easty* · 03-27-2007

it's not relatively the same for different WU. So a larger WU could have less frames. or vica versa.

I searched and found this mate. Not lamens speak, but best i could find

......

Both frames and steps are particularly important from the scientific perspective. I think I understand all of the following terms, but I've never seen precise definitions, so if I'm wrong about them, somebody can correct me.

The fundamental unit of calculation is a step, and the position of each atom is calculated at some very small increment of time. Once the positions and forces are known at a particular time, they can be used to predict the positions at a later time.

A series of steps is combined into a larger block of time normally called a frame (but the term is not always used the same way). Those positions are recorded on disk. I think that those positions are also uploaded for every frame, but I'm not sure that's always true. When you see an animation of protein motion, you don't see every step, you only see every frame.

Depending on the number of atoms, the speed of the computer, etc. the time to calculate a single frame can vary widely. The number of steps per frame is specified by the PI, but will be different for different proteins.

To minimize repeated calculations when you shut down FAH, a checkpoint is written to disk. It generally represents a different number of steps than a frame. They're not treated the same way in all cores, but they're like a frame in that they create a record of all the positions on disk so that FAH has enough information to restart, but they don't need to be permanently recorded because they're not necessarily going to be uploaded to the FAH datbase. For most cores, a frame also functions as a checkpoint, but you can have extra checkpoints within a single frame.

Another block of steps is called a Work Unit. The actual number of steps and the number of frames in a WU may be different from other projects, and the size is determined by some balance of how frequently the Pande Group wants a typical machine to upload results and the size of the uploads.

By stringing together a series of WUs, the Pande Group obtains a simulation or a run which is what they're really looking for.

I've generally gone from small to large. Of course you can always break down a step into individual calculations.

Thats funny, a little competition could makes things a little more interesting.

*easty* · 04-02-2007

Congrats cruzer_7 on your first unit. may it be the first of many more.

Brian:
Gene's was 5,000 and remember mine said something like 141 days for 50,000.......well, it will be done this afternoon....Yeah!!!!!!!! Thanks for helping us get it set up.... gives us one more little tid-bit of interest in our lives

Hugglies, Jo

*easty* · 04-03-2007

My pleasure. the SLKWorld team is slowly aproaching the top 4,000 teams. Keep it up guys.

Tslick · 04-05-2007

Brian, Gene's machine is a number cruncher

9PM 4/5/07

*easty* · 04-06-2007

Haha, you best get shoveling in the coal or you'll soon be passed.

Wooo... that #5 Eric guy must have really sweet machines.

**etyu** · 04-08-2007

Way to go Eric!!

Tslick · 04-09-2007

Wow, Eric_Lyna number crunching machine is like a AMG. A monster.

**ghostdunks** · 04-13-2007

realised I had a work lappy continously connected and sitting here on 24/7 doing nothing most of the time, so I got the app, and started folding! Hope to appear on the leaderboard soon!

Thats great mate good to see you on there. It's fun watching. Eric has made an amazing entry to the game and shot straight up there with equipeduciel. Wolly and tslick keeping taking each other and cruzer_7 also made a huge jump up the graph. I'm looking forward to getting back in the game.

Also don't forget if you have a PS3 you can also join in with that. Certain ATI graphics cards can gain a huge advantage, if you know your GPU then check the specific apps on the Folding site to see if yours is compatiable. I've read there trying to get a Nvidia app released. GPU are designed to crunch numbers in this way so they go through GPU's like you wouldn't beleive.

Gotta put these machines to good use! They're on anyway, what's a tiny bit more heat in the name of medical research?

I do have a PS3 which I was thinking of setting it to Fold as well, but I didn't want it running 24/7 wearing out the fans/HD/etc especially since its new... this work lappy though, it can self-destruct for all I care, work will just get me a new one

Eric_SLK320 · 04-24-2007

... looks like I'm going to have to add a few more machines to bypass //AMG.

*easty* · 04-24-2007

Congrats guys you broke the 4000 mark and are now at 3,837 of 62,279. keep up the great work,

but ghostdunks may be more
