Look who's crept in a No.11
Not even back for three days and he's already scoffing crumbs :rofl:
:welcome: back Poppa :buddies:
Yeah. I've finally found a thread that gives estimates for PPD for different Video cards. http://www.xtremesystems.org/forums/...d.php?t=246434 shows that I shoudl get between 34.7k and 42.0k PPD from a GTX 275. Unfortunately, neither my linux box or HTPC gets those kinds of numbers. The linux box is dedicated for GPUGRID and WCG and yet it gets only 13k PPD(GTX 275-it took 30 hours to complete one task!). My HTPC gets a slightly closer 34.5k PPD. Strangely my SR-2 gets an amazingly low 25.5K PPD. I'm very confused by the lower PPD I have. Currently I have 2 GTX 275s at their stock speeds(I don't think they are factory OCed) and 1 GTX 480 and yet I'm fighting for 100K PPD from all 3 combined. Doesn't seem quite right. I have the Swan_sync variable set for the GTX 480 machine. But my PPD just seems very very low.
I'm trying to figure out if I can give GPUGRID "priority" over WCG, but everything I read seems to say they will split up their resources efficiently(which seems to contradict what I am seeing with my machines).
If anyone knows of any special tricks to maximize GPUGRID PPD please post here or PM me. I'm currently looking at disabling WCG to see if that will help GPUGRID. I'd only be doing it temporarily to prove my hypothesis. I'm not convinced that 75kPPD is really what I should expect from these 3 video cards.
Thanks,

mmm...gimme ma pie !!!
@Josh,
Yes, you should be getting much higher PPD.
1. If you are running with newer drivers and the 6.12 application version of GPUGrid you should add the SWAN_SYNC environ var for linux. This is a change in how they configured the app itself. Previously it took 1 cpu thread all by itself, now you need to tell it to. You will have to stop and restart BOINC itself for this setting to take effect. Make sure to Set BOINC Manager to use 1 less cpu thread less than you actually have to free up contention with WCG.

2. Make sure your GPUs are not downclocking. Not sure how you track this in linux, maybe another linux gridder can help you out here.
@OllyK - with the fire power at your command, surely you can do better than pigeon (grey) pie :rofl:

@Snow Crash,
I've started a new thread discussing my problem. I'll add the sway_sync variable when I get home. I'll have to read through the thread you linked and see if it explains how to add the system variable.
If you want to see my thread, go here. I discuss all 3 of my systems that are cruncing with GPUGRID and my observations.
Rawr! My points have increased! I'm so fierce ;)
I installed XP and today my score is 130k, 150k in Bionic stats but tomorrow have to return borrowed MBO and then I am out for 2,3 days, until my MBO come from RMA, but when I return i will be stronger than ever.
Those are some nice numbers roki. You will be a force to be reckoned with.
