Yes, that's one problem with the current OpenCL Apps. The Binaries have the same name no matter which driver is being used. Then the App tries to use the Binary that was complied with a different driver. It usually doesn't work very well. The Binaries have to be deleted manually, or by a project detachment. Adding the Driver Version to the File Name should solve that problem.

Not really.

I told Raistmer not to do that.
Lets say one installed the app with a good driver.
Some time later he installs a faulty driver the app wouldn`t work anymore.

This way the app will still use old binaries and will still function properly.

We have to think about set up and forget members as well.

As soon as he changed back to the good driver it would use the 'good' binary. No problem. Having to have people manually delete files is a problem. I wish I had a dollar for every time I instructed people how to manually delete the binaries.

Right, those are the ones constantly producing Errors or Invalids and don't have a clue why it doesn't work...

Ah ok, well the 'cypress_xx_r1831' files have all returned, as has the v7 file, I can see no differences in the file name (old ones in recyc bin atm), yet the deletion worked!
Could the files be different versions with identical names??

Yes of course.

I suggest to use the installer since more recent apps are more mature.

Which installer? I've already got the most recent none beta version of BOINC....

Oh & I agree that new binaries should be installed when the driver's changed, what a PITA! :P

Ah ok thx, I did say in my 2nd post that I wouldn't be installing the optimised apps until I've got ~12 results from my 5850 (which I haven't got yet, 3 pending so far), I guessed they missed that ;).

The apps I had were the original ones from SETI when I had Cat 13.1 installed.
Hence saying they were SETI files (which they were :P).

Anyone know if SSE 4.1 is the best for my CPU or not?

To be sure how fast the optimized apps is on your host you need to compare WU with similar AR for MB or blank for AP.

At one time the SSE4.1 app was fastest on Core 2 Duo system with very fast(overclocked) RAM. The best way to know for sure it to run each app on your system and compare them.

On my C2D E8400 I had the best results with the SSSE3 app.

At the moment I am comparing the SSE and AVX apps on my two i5-4670 systems to see if either shows a significant advantage to the other.

Back then, the SSE 4.1 build was done without the "x" option, so it did some logic with a smaller stripe than most of the other builds. That worked out best on Jason's highly tuned E8400 system. Now all the released Lunatics AKv8c apps are using the "x" option. That way I only have to make 14 different builds...

The difference between the SSSE3 and SSE 4.1 builds now is basically just whatever GCC 4.7.1 optimizations chose to do differently, there's no explicit use of SSE 4.1 instructions in the source code. There were differences in performance seen during our alpha testing, but I won't go further than saying that for a Q9550 the SSE 4.1 build ought to be marginally better than the SSSE3 build.

                                                                 Joe

Ok, thx guys, interesting.......

A few questions, what is the 'x' option? what do you mean by a smaller stripe? And what's GCC? ;)

Incidentally the FSB is quite high on my rig at 424 MHz, so it shouldn't be too much of a bottle neck, although it will be far more loaded than on a dual core rig of course.

I'm comparing WUs of similar credit, I thought this related to AR but my 1st check of 2 similar credit WUs show they're different :(, damn!
Is their a quicker way of checking AR without going into the task details of every WU I want to check?

Btw I didn't use any AP WUs in my comparisons.

Similar credits is diferent than same AR why, due the creditscrew mess, the number of credits depends not only on what your host do what your wingmen host do counts to.

The only way i know is by looking each WU task details.

Back in 2007 or so when Alex Kan wrote many of the optimizations for Mac Pro systems, some had Intel XEON CPUs and some had consumer type Intel CPUs. Alex found that they performed differently enough to justify targeted builds distinguished by a USE_I386_XEON preprocessor define. The "x" indicates that define is on.

After doing FFTs on the data, it is converted to a set of powers and reorganized by transposing the order so analysis for signals can work with consecutive values rather than needing to access sequential values at some inefficient stride. Those operations are done with the ouptut of 4 FFTs for the non-x case, 8 for the x case. That's what I meant by smaller stripe. The are other differences too, for instance the non-x case combines the two operations, the x case does them one after the other.

GCC is the GNU Compiler Collection.

                                                                  Joe

Your 2nd paragraph was over my head but thx anyway ;), roger on the Xeons though.

Ok thx, what a PITA! ;)
Nothing like old SETISpy to show ARs then? :(

And for some reason my stats are now showing 'anonymous platform' for both CPU & GPU....

There might be an app somewhere, but you can just look at your returned result.
http://setiathome.berkeley.edu/result.php?resultid=3693821319
Then look for: WU true angle range is : 0.448223. With 0.42 being around normal AR.

Yea I know but it's a right pain looking at dozen+ like that.
And I think the std app results have gone now too.

Interesting that the average AR hasn't changed much in years, I remember the SETI classic benchmark WU was 0.417 ;).

Well the earth hasn't changed it's spin rate much since 99, so a Normal AR stays the same ;-)

(A Normal AR Wu is produced when the telescope is stationary, the earth rotates, so there is a change in where it was pointing,
A Very Low AR is where the telescope is pointed to a fixed point in space, when the earth rotates the telescope moves to remain fixed to that point in space,
a Very High Angle Range is when the telescope is actively moved around the sky)

Ah, thought it would be something that simple, lol, I couldn't remember what AR was really! ;)

Btw, is the 'anonymous platform' just what the optimised app gets called? If so how come the earlier WUs it did (some of which I pasted above) didn't get labelled that?

Anonymous platform

Anonymous platform

BOINC applications are native-mode programs, so different versions are required for each platform (a "platform" is the combination of an operating system and a CPU architecture: e.g., Linux/Intel32). Each BOINC-based project has application versions for one or more platforms. When the BOINC client requests work from the project's server, the client tells the server its platform, and the server gives it the appropriate version.

This addresses the needs of most BOINC participants, but it's inadequate if:
## your computers have platforms not supported by BOINC or by the project;
## for security reasons, you want to only run executables you have compiled yourself;
## you want to optimize applications for particular architectures.

To handle these cases, BOINC offers a mechanism called anonymous platform. This lets you build applications yourself, or obtain them from a third party, rather than getting them from the project server. This can be used only for projects that make their source code available. As an example, see the instructions for SETI@home.

If so how come the earlier WUs it did (some of which I pasted above) didn't get labelled that?

Earlier work will have been tagged as Stock work, the app_info will have entries corresponding to those tags so work won't be lost,
the server doesn't know that those Wu's are now getting done by a different app so won't change it's entries.
(unless you're messed up adding the correct tags, then the work gets lost and the server resends it on the next request as Anonymous platform)
