Well... I can also tell it much easier: SHIT CODE! :p
Please give us back v6!

IMO, since V7 does so much more going back to V6 would be the waste.

The gentleman originally being quoted does not apparently realize that the basic science being performed on the data is now different. So comparing 'performance' of the two types of tasks is irrelevant.

I am looking forward to his return with the CUDA application re-written in hand-crafted assembler code. If he can achieve that, then he will have earned the right to say every word he's written.

But I'm reminded of a certain other purveyor of vapourware, who promised that he could write code that would run on his employer's CPUs faster than any GPU. Sadly, it never happened.

So version includes auto correlation which, I assume based on reading the wiki, makes it more sensitive to weak signals? That's certainly a good thing. I'm still curious to know exactly how much more sensitive it makes S@H, and if there are any other improvements in v.7...

I am new to the program, and need help. I am logged in, but not sure if I'm doing something wrong. I'm not sure if the programing is complete or if I'm missing a step on getting it to activate so that I can start the search.

Any idea's?

It looks like you are up and running.
OBTW this question probably is better for Number crunching forum.

Tomorrow I'll post explaining why we wanted version 7 and what's different about the analysis it does.


So... what changed? I'm waiting for that post :)
I'm very curious about it!

I see i'm not alone who is curious :D



we are still waiting :P

If the intended recipient of the signal knows what period is used for delaying the combined copy of the signal, that can be used to enhance reception. We don't have that knowledge, but we can examine signals to see if thay have a delayed component and put the measured delay in the science database so if it is seen again from the same sky pointing maybe the signal is intentionally being sent that way. IOW, it's a new kind of signal search rather than increased sensitivity.

There have been other improvements incorporated in v7. The stock CPU application has functions using the AVX instructions on systems which support them, and use a newer and more efficient version of FFTW too. There has also been work done to tighten the accuracy of some calculations which should reduce the number of inconclusive validations between results produced by CPU and GPU. That won't be obvious, many of the inconclusives are caused by systems which are temporarily or perhaps permanently unstable, and others when there's an overflow are caused by different processing order.

I read somewhere, after I kept getting messages about no GPU, that the new version BOINC or Seti7 needed a graphics of 2.2 and my GTX 550 Ti is only 2.1.

This means no CUDA processing. Is it possible to get the earlier version as it seems crazy not to use the GPU, even if it is not as quick.

Any help please. (Not really computer savvy)

The one with the i7 processor i assume?!?! Goto nvidia.com and download the latest drivers for your 550, that will most likely be the problem as there is no gpu being detected on that computer.

Or it could mean he's done a Boinc Protected Application Execution installation (aka a Service installation)

The i5-3210M is erroring all it's Cuda and OpenCL Wu's, it's running the Buggy 296.xx drivers with the Sleeping Monitor Bug, but i don't think it's because of that, the error is 'couldn't start app: Can't link app version file' for both apps,
he could try updating the Nvidia and Intel Graphic drivers on that host too.

If he's running Win7, every time he restarts the computer, he needs to open Boinc Manager, go to File > Exit, wait a minute, then start it again. Boinc doesn't detect GPUs when it autostarts in Win7.

[edit]
I think this is the same thing Claggy just said, only I put it a way a "not computer savvy" person can probably understand.

Yes it is an HP with i7-260, running WIN7 64.

I have tried exiting BOINC and restarting. I now await to see if any CUDA data appears.

I am running Milkyway, Einstein and Seti.

Thank you for the info. Fingers crossed.

Just noticed your reply, I only saw the later ones. I do remember an option on the latest upgrade install which seemed to suggest a better install option. Your comment seems familiar. It didn't really understand what it meant, but i did not think that there would be an option that would cause problems.

"Or it could mean he's done a Boinc Protected Application Execution installation (aka a Service installation)"

Again your help would be appreciated. I only want the prog to run as it used to.

In

Did you click Advanced?
And then in

Did you click Service Install?

My problem is a little different. I have two GPU's, not SLI and up until a few days ago, SETI was running on both. Now it only recognizes my GTX 660 Ti and not my GTX 650 Ti even though my cc_config.xml reads:
<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

It sees both, but BOINC Manager says GPU 1 not used

Ah yes Ageless, I saw the increased protection, obviously missed (HOW?) the not use graphics card !

I hope there is an easy way out.

It is a good job there are people like you who are knowledgeable !

The only way out is to uninstall BOINC (Control Panel\Programs\Programs and Features) and reinstall it from the installer. Then uncheck the Service Install. :)

Note that this procedure is safer than it sounds. Although the uninstall/reinstall process will remove and replace your BOINC programs, all your SETI information, like tasks in progress and account statistics, are kept in a separate place and will be unaffected - likewise, any other projects you are crunching for.
