F@H Questions/problems

NightmareXX · 27 Jan 2010 at 10:46

Well as I said, I've now used up all my BOINC units so I've switched to F@H to see what sort of output I can give. However, I've a few problems and questions that I can't seem to find the answer to so I thought I'd as you lovely people here

http://nightmarexx.is-a-geek.com/fah.html

Firstly and perhaps most importantly, my GPU (GTX 285) doesn't seem to be working properly. It's the GPU system tray client and last night it stomped through a unit in about an hour. However, as is visible above, it now seems to be struggling with a unit. Checking the unit by displaying it confirms this, the simulation pauses more often than it's running! Why?

Secondly, should I run 1 or 2 instances of the SMP client for my quads? A recent forum post I read said 1 client using all 4 cores gave more PPD than 2 clients assigned to 2 cores.

Thirdly, do those PPD numbers look right?

Thanks in advance

EDIT: Reinstalled GPU client and it seems to be playing ball now

Ah ha, excellent.

When I get home I shall switch to HFM.NET, sort out a single SMP client for all of my quads.

I've checked my graphics card and it hasn't throttled back. I've been using VNC to connect to my PC to check. I've ticked the higher priority now

I don't watch the pretty graphics, I merely use it as an indication of whether it's working or not.

Sorted a few things out, now have a single SMP client on each of my quads.

I've seen some mention over using the -forceasm flag. Should I use that on both my AMD and Intel systems or not at all?

I've also noticed that my Q9450 appears to be running 4 instances of something whereas both my 940 and 810 chips are running a single process using up 100% CPU time. Is this to do with the new A3 core that's coming out?

Also, in HFM.NET, some of the status bars are yellow and I can't work out why. It says "RunningNoFrameTimes". What does that mean?

Will my Q9450 get the A3 core when it gets a unit for it or is there something I can do to force it to get the newer core?

Well if you check my page I've got all my machines on the job. They're producing better than I expected

I'll try and pick up another graphics card at some point too ;-)

Well my GPU client seems to have killed itself again. Downloaded a new core (FAH_14) and project 5912. It simply refuses to load the GPU to full and there's no reason why not. Hsa been working perfectly fine all day.

Thoughts?

Well previous units would complete in just over an hour and each frame would take about 1 minute. However, with this new unit, each frame takes an incredibly varied length of time and does heat my GPU up at all

My PPD is almost halved too!

Here's my FAH log. The time between frames is still far too big

I get much better PPD with the older units.

I've changed the checkpoint to 15 minutes although no change yet.

I am running SMP and it's crunching on all 4 cores although with other GPU units it didn't have an impact. Currently doing a 6012 unit.
