GPU folding won't run when CPU folding is running

[ho_k]

Just resumed folding part time on an old A64 x2 4200+ machine. Just added a GTX 460 in. I notice that when CPU folding is running, it stops the GPU folding. Machine ID is 1 & 2 for dual core CPU, and 3 for GPU. Wondering if I missed something?

Thanks

Well assuming it's a dual core machine, i dont htink you can assign more than 2 cores/threads.

It would be best to just run the GPU client.

agreed
i do this on my laptop
best to just run GPU

Welcome back, Try using FAH GPU Tracker V2.

I tryed the same thing recently on an X2 4400 and was only getting 5-600 ppd on the cpu. not worth it now days.

Love the old school sig. (close second to Fatmantan's..)

Has anyone archived the old pages for these?

Yes, it is a dual core machine. I was setting 2 instances for cpu folding (1 each core) and 1 instance for gpu. So, is there a solution to get all 3 instances to fold at once? Machine IDs are set 1, 2, 3 respectively.

[Fatmantan]

As mentioned, you will not be able to run both CPU and GPU on a dual core cpu with any great success. Run GPU only.

I'd suggest trying 1 instance on cpu and the gpu as well and seeing if that works at all.

[RETARD]

its possible leroyxx but assuming its not a dedicated machine it does get long in the tooth when wanting to open applications etc. I find that the GPU client more or less doesn't affect the machine in day to day use.

Leaving one core to handle the gpu should leave the machine reasonably responsive... heck I'm running on all four cores at the moment on my main pc and in use and there's no noticeable slowdown, SMP slows to let me do what I wish.

However I did use to run a P4 1.7 - single core, and with that chugging away it was fairly slow, but I hardly ever used it, it was a net box in the lounge for visitors lol.

What is a passkey? Can you use it on more than 1 PC?

I installed your utility on a Q6600 machine with 9400GT video. The machine kind of intermittently freezes / lags terribly when the GPU folding is running. Any suggested fix?

A passkey is user based. So yes you can use on more than 1 pc.

As for the second part. That GPU is useless for folding PPD wise. Stick to SMP

It now says:

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

I tried the Tracker at home. GPU would stop folding as soon as an instance of CPU or SMP folding kicks in. Can't figure out why.

Does everyone here do GPU and CPU/SMP folding at the same time?

[Fatmantan]

/exits thread.

If you wont listen to our advice why keep asking?

MACHINE 1: Stick to GPU ONLY
MACHINE 2: Stick to CPU ONLY

Both machines arent specced high enough to run both at the same time.

IF you decided to stick the 460 with the Q6600 machine then you would be able to fold both at the same time.

Most people (aside from those playing with bigadv) run SMP and GPU.
However tbh most people are running on hardware with significantly more resources than your talking about.

The GTX460 running the gpu client will need one core just to feed it for want of a better explanation, as the client still uses a significant portion of cpu time to deal with the calculations being sent to the gpu and to deal with the output.
Hence why most people dedicate a core or HT core via a process manager or similar just to keep the gpu client supplied with enough cpu resources.

However as your running the SMP client as well across both cores, i'd suggest the SMP client processes are hogging all the cpu time available hence the gpu output goes to zero.

One option is to use a process manager like Bill2's so that when the gpu client starts its process gets higher cpu priority than the smp client processes. Result will be lower SMP output but the GPU client will get its share of cpu time.

Alternatively scrap the SMP entirely and install a uniprocessor client , give it core affiliation via a process manager to one core, also have the gpu client instaled and set its process affiliation to the second core.

You'll still get some points from the cpu, but it should give the gpu a good go at some reasonable points.

As to the freezing/lag you mentioned when running folding, based on the hardware you described its just s result of the fact that your flogging the hardware at 100% load, as such all the other processes , explorer , your browser etc all have to join the queue for cpu/gpu time.
On higher performance rigs its less notable and just results in a small drop in performance for everyday tasks, but if you try to run anything that is cpu or gpu intensive you certainly will notice it, its just much more evident on lower performing hardware.
