Yes, sometimes the servers are just really busy.

One other quick question.

If your internet connection is unavailable when the WU finishes, will the program continue to retry access, or will it die and lose the WU.

The reason I ask is my home rig is on dial-up (yeah, I know. I live in the sticks), and it is our only phone line. I cannot guarantee that the connection will be available when the WU finishes. (especially if it finishes while I am at work or something).

 

[D007]

I wish I understood this..lol..

 

[Steevo]

It loads the results into the cue untill the next opportunity comes along to send it.


And the only possible way for a WU to "die" is for it to be past the deadline, and that is not very likely as they are generous, or if it is a early finish unit that has become corrupted.


Of their servers some are for sending, some for receiving, and some for processing the results, however I believe they are running their systems to the full all the time, based on my past experience.


And I have alot of machines running, and been doing this for awhile, this is my second team, and hopefully the last team I fold for.

Thanks for the info Steevo, I will again resume folding on my home rig.

I found some interesting things. When running the SMP client, all four cores peg at 100%.
When running the non-SMP core, but setting the CPU utilization to 100%, it splits the load over the cores so each core is running at approx. 25%. This is the same on the Pentium D I am running at work which uses 50% usage on each core.

Using the non-SMP core, I am pumping about 50000 steps (out of 5 million) about ever 12 minutes. If I remember correctly, the SMP core was pushing 50K in about 8 minutes. (on home rig)

I think I will keep using the regular core as it's getting a bit warm here in Cheeseland and the wife doesn't want to turn on the air conditioner yet.

My cores are running about 20C over idle when folding. (hottest core at about 62c)

When Thermalright comes out with their 120 Extreme or the IFX-14 (or whatever it is called) I will see if I can get some lower temps with a better cooler.

I am glad to see people are still folding to help medical science.

 

[Alcpone]

@ Alcpone, when you first opened it, it asked for you to put yes/no ? Cuz did you put the one they suggested of did you put what ever ?

I just put what was the better option LoL, cant remember what I put exactly? I might try and set it up again and see if that makes a difference, cant be lagging behind in the wu's for long or you will catch me up

 

[Alcpone]

Alcpone,

When I first loaded the SMP client I also got the "Attempt to get work failed". I just let it loop and eventually it grabbed a WU. On the second try after the first WU finished it got one immediately.

The communication error is thrown (I think) when the SMP client sees a non-SMP type WU in processes. It dumbs it and tries to get one it likes. If I recall correctly the SMP core will only try to do large (>5MB) type WUs. Also, I think the SMP core will not restart a WU and will always get a new one if you stop and restart the core (unless they updated the program since the FAQ was written).

On another note, I broke into the top 20 !! WUhoo

I will try and work it out, see if ive done something wrong, thanks for the info

Keep up the feedback, I will return to the SMP core to help you troubleshoot if need be.

It cooled off tonight so I bumped up to 3.03GHz.
Temps are about the same, but not seeing a real boost in frame processing speed.
(maybe about a minute or so better)
I may need to go back to SMP core to see a real boost.

Stupid ticks are horrible this year in WI. Had to stop writing to pull one off me.

 

[Kreij]

Running tonight at 3.104 GHz.
Using SMP A1 core. All 4 processor cores at 100%.
Hottest processor core at 71c.
Turned fan speed on GPUs to 75% in 2D mode just to get heat out of case.

No one probably cares, but I'm having fun

Keep folding my friends ....

Lucky bugger, I cant seem to get the smp working still

It is kinda fun doing it for the good of mankind and when they find cures we can be proud that we contributed something

 

[Steevo]

I finished two GPU clients, however I cut my phone line at home last night while grading my yard with a skidsteer, so it couldn't send it and no net till I run a new phone line.


But at least my yard is almost ready to plant. 6:00-9:30 in the skidsteer and I feel like someone has beaten me.



I care, I just wish I had that much power working in my home PC. That would be sweet. For now I must be happy with my 4000+.

 

[Kreij]

Did you try deleting it and re-downloading it? Maybe it got corrupted on the way in.

 

[Kreij]

I had to back off a little (down to 2.7GHz) as it's a bit warm this evening in Cheeseland.
I don't want the system to do a thermal shutdown or throttling while I'm folding

The SMP core will continue where it left off with a stopped WU. I thought the FAQ said that it would not do this, so they must have updated that in one of the later betas.

@Steevo ... How intrusive to users is the Fah-Core when running as an Idle-set process. I was just wondering as, like you, I am a Network Admin and could potentially bring about 40 more systems online folding. I have one running on my machine at work and I notice some delays when doing little things ... like compiling code projects.
Thanks for any info you can supply.

 

[newtekie1]

I'm not steevo, but I can say that for the most part it is pretty unnoticeable to users. Anything that needs the CPU to not be sluggish will have a higher priority and use the CPU over FAH.

There are rare cases where something is set to a low priority(compilers can do this sometimes) and FAH will cause sluggishness sometimes, but nothing a normal user should notice.

Thanks for the response newtekie.
I remebered after I posted that I had set the core priority to high on my machine at work. DOH!

I think I will talk to the president of the company soon to see if I can get his blessings to put our computers to good work on the off hours.

Has anyone seen any issues with folding when things like automatic virus scanning kick in on the off hours ?

 

[Steevo]

Depends on system load.


I can manage it but on a few machines that don't have at least 512 of RAM I won't put it on, and laptops that are actually taken out of the place are not to good to run the client.



I have a flock of mostly P4 2.4's with a few better performers. The latter half that actually do the folding work for me are the ones I built, 3.0Ghz of better with a Gig of ram. Only three of the 2.4's actually fold due to lack of resources during the day.

 

[newtekie1]

I wish I had your folding power steevo. I would put it on some of the computers I manage at work, but I got pissed at a few users and decided to completely remove internet access from every single computer excpet mine and my boss'. Soon they will learn to not call their System/Network Admin "the bottom of the totum pole".

 

[Steevo]

My peeps have learned.



I just get the content filter back going again, and forward some of their e-mail to the boss for a few days. They get hot around the collar and are really nice to meh.

 

[newtekie1]

I swear, they are like kids. Sometimes the only way to get their attention is to take their toys away.

 

[Batou1986]

i just started folding with my 1950xt lets see just how fast this thing can really fold i don't believe it makes it 10x faster then usual but i don't really know much about F@H as i just started today

running the console fah 5.19 beta 3 for ATi atm Batou1986 tpu team

lol my gpu is peaking at 71* so its doing something

wtf happend to post count i know i had more than 421

 

[Kreij]

Welcome to the team Batou !
Let us know your approximate times and WU sizes when you get a few done.
I would like to know a little more about GPU folding.

I could use my pair, but I think you have to take them out of crossfire mode to do it.
Not sure I want to be switching back and forth all the time when foldng or gaming.

The post counts got mesed up a couple of days ago. Some forum admin goofup I think.

@Steevo & Newtekie : LOL .. The people in our plant don't give me any grief. Living out in
the sticks helps as many of the people have been there for many years and we're all pretty
close friends. Is someone gets a little insistant about interrupting what I am currently
working on, to handle their request, I tell them, "I'll put it on the whiteboard".
Which they know means it may not happen in their lifetimes.

 

[Kreij]

On another note, the problem I have at home is that using the SMP client the core downloads very large WUs and it takes about three hours to send the results on dial-up.

Grumble ...

 

[Batou1986]

Well im not to sure how all this works but since about 1am last night to 10 am this morning i managed 171 score and 1 wu is that good ?

Nine hours is fast. How big was the Work Unit?

My system at 3.1GHz was running though 50,000 steps in under 7 minutes (on a 500K WU).
So approximately 11 hours for the whole WU.

When I backed it off to 2.7GHz it was taking a little over 8 minutes for the same amount.

Cuz your usng GPU right I always get 300 something Score on every WU and get lil under 200 Score on my P4

how many secs per frame are you getting ?
