The other point that occurs to me is "Has SJ actually run out of work because of the 24 hour back-off?" (He obviously can't answer this himself since I am blacklisted). As Richard says, if the VLAR killer returns 100+ consecutive VLARs then the back-off will be 24 hours but only until a non-error is returned and there should be plenty of those well within that 24 hour period so all it needs is a click on the "Update" button to report them isn't it?

I had 60 VLAR kills in a row at BETA so I 'hit the daily quota' so to speak for 24 hours. Even so my GPU kept crunching happily here.

SJ the lagging of the screen is not a boinc problem. it is a cuda problem.

try for example folding at home and you will experience the same behavior on nvidia and ati powered gpu's like on seti main.

best solution i found is to buy a second cheap video card and make that the primary display rendering device.


another important thing is that the graphic card should have as much mem as posible.

on the same host i tryed a 8600gt 256 ddr2 and 512 ddr3. the first had given me quite a headachei doing anything else than cuda. on the 512 it was much better.

you can make the host always connected so right after a workunit is finished it will be reported. so you will never reach the minimum daily quota,

If so then fine return My donation in full, Immediately or as soon as possible.

I'll bet they could send you a handbag of equal cash value. Right Pappa?

If I beat the dead horse it only has one more mile to run.... Then I am home...

I know. Problem is I didn't have any non-VLARs at the time so I didn't have anything else to work on and upload.

In My case I have two pci-e slots that would be usable for a video card, One is a true 16x and the other is a 4x slot that looks like a 16x slot as It's a P35 chipset Asus P5K Deluxe and I'd have to add either a slower 7800GTX w/256MB of ram(80w) or an even slower MSI NX6200TC w/128MB of ram(??w) in a 2nd PC so that one is out. The card I have now is a BFG GTX295 and buying any other card right now is out and being My budget is based on My $870.00 a month SSI income, The money won't go there and I don't want to use another 80w dual slot card in the 16x slot and the PC as far as I know won't boot from the 4x slot.

As it happens, I had an email today from the nVidia developer who did a major part of the port. He said:

I am aware of the VLAR sluggishness and have spent some time trying different way to resolve it given the current pulse detection algorithm with not much luck. The bottom line is that when using CUDA on the same GPU that also used as the graphical display, it is difficult to prioritize one type of GPU client over another on the current HW architecture. SETI@home is not alone, this issue can affect any CUDA application that demands high amounts of time from CUDA.

That adds an interesting question: is there a way to reduce the "graphics" demand on the card if the owner is mostly interested in crunching.

Setting the display to the minimum resolution and the minimum color depth might make a difference -- and would be an interesting experiment.

I wonder if some of the same kind optimizations (rearranging execution order) that help the CPU apps would help the GPU apps.

There are two problems with the VLAR tasks.

1) They take absolutely ages

2) If they are running on the GUI GPU, they cause sluggishness and lagging on the display and other applications using that display.

SJ's problem is with (1). I have every sympathy. I don't do VLAR on CUDA either - it's not worth it. But I use a more sophisticated workround - one developed, as it happens, by Fred W, who is too modest by half. SJ, you should learn who your friends are, and reconsider your decision not to listen to Fred W. You might learn something to your advantage.

Problem (1) is the hard one, and nobody seems to have a solution. Jason Gee is working on it - he found a reference today which may help: "WooHoo, Found it in Bailey's paper. "FFTs in External or Hierarchical Memory", David H. Bailey December 30, 1989. Ref: Journal of Supercomputing, vol. 4, no. 1 (March 1990), p. 23{35". But don't hold your breath.

The nVidia developer's concern - today - was with problem (2), the screen lag. He had a useful suggestion - make the new "don't use GPU while computer is in use" option in BOINC v6.6.20 apply only to GPU cards driving the user interface display - which I have forwarded to Eric and David. Watch this space, as they say.

Thanks for reading my post. I thought I had read the vlar was included in the 6.6.20, my mistake. I was unable to find the release notes on the boinc site so sue me.

I'm still waiting to hear it SJ tried Raistmers v.11 CUDA app?

you could have disabled cuda. and crunched from an earlier backup of boinc data dir

I've been doing that for a long time already. But thanks.

Clarification of My last post Only: So not crunching on the gpu that does the video is not a practical idea(It's a stupid idea really) I'd think as GTX295 cards are an expensive minority of CUDA capable cards, In which case only GTX295 Cards or those people with more than one CUDA capable card would crunch, The rest would just do video and no CUDA.

The option would be when the user is active. If the user is not active, then the system video slow downs would not be a problem.

It is still a stupid idea.

Why? If the user is having trouble with the display, wouldn't it be a good idea t turn off crunching on the display while the user was active?

then why did I buy a GTX295 card???? It has two gpus silly, Disable cuda and I may as well quit as that's a $480.00 investment with shipping.

What earlier backup? I've been doing cuda for more than a week, So If I had one You;d expect Me to try and crunch as before with just the cpu, You also have backup the Boinc folder as well as the data folder in It's entirety or the backup wouldn't work.

Then I guess I wasted My money in the video card of My choice as I spent $480 total so that I could crunch with both cores(gpus), I hate typing.

SJ try updating youre video drivers to version 185.68.

i obseved an amelioration of the slugishness. maybe it helps you too

SJ try updating you're video drivers to version 185.68.

I observed an amelioration of the sluggishness. maybe it helps you too

When I feel like doing that I might, Generally I like the WHQL drivers as 185.68 is beta last I looked.

The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's

try then with the new whql non beta version 182.50

A video Guru may correct me if I'm wrong but I believe BOINC will see multiple GPUs as a single graphics card (ergo a single GPU) much like my system sees both harddrives as a single RAID drive.

Which would be almost never as I spend more time on a PC than some people, Why You ask? Cause I have the time, about the only times I'm not at the PC is when I'm asleep in bed or taking a brief nap in the recliner(beds too hard for more than 6 hours sleep and I get that), Or unless I'm indisposed, Or I'm washing dishes or if I'm outside(rarely, I'm disabled, summer is worse) I'm almost always here as It's something to do as I've seen what's on TV ad infinitum. For what isn't on TV I buy a DVD when I can as the budget is cramped and It might get smaller soon once again, This last month I got $907, In May I'll get $870 and in July I might get $829 or even just $674 and $674 is doomsday to Me as I collect SSI benefits(Federal $674)/SSP(California $196).

Remember You asked for It, The GTX295 has two gpus as You said, For the card to be used as two separate gpus, SLI must be disabled and I've done that already, But It's at stock speed as this card uses 209w more than the 7800GTX(80w) that the GTX295(289w) replaced.
