Message 8675 - Posted: 19 Jan 2009, 19:50:21 UTC

I've updated the code releases directory with the v11 source code.

If you look in the makefiles, there's two new flags that need to be set when compiling the application:

APP_VERSION = 0.11
APP_NAME = your_app_name

-DBOINC_APP_VERSION=$(APP_VERSION)
and
-DBOINC_APP_NAME='"$(APP_NAME)"'

This will let us know that the application was compiled as version 0.11 by "your_app_name".

The stock app is using:
APP_NAME=stock
so please don't use it for your own compiled applications.

We're doing this because of the problems we're having with some of the current optimized windows applications, which are returning incorrect results. So as of tuesday/wednesday, we'll not be awarding credit to applications compiled without these flags (ie, those that don't write the app_name and app_version to the WU's result).

This will let us know where our results are coming from, to help us debug our searches, and help you debug your optimized applications.

Also, unfortunately, I think this is the only sure-fire way to get people to upgrade from these incorrect applications. Our dynamic error checking isn't working yet, mainly because too many bogus results are being returned by these incorrect applications; which throws off those calculations.

The source also has three new test parameters (for stripes 79, 82 and 86, respectively):
astronomy_parameters-79.txt
stars-79.txt
search_parameters-79.txt

astronomy_parameters-82.txt
stars-82.txt
search_parameters-82.txt

astronomy_parameters-86.txt
stars-86.txt
search_parameters-86.txt

To test these, simply rename these files, ex:
cp stars-79.txt stars.txt
cp astronomy_parameters-79.txt astronomy_parameters.txt
cp search_parameters-79.txt search_parameters.txt

I've added the set_parameters.sh to automate this, just run ./set_parameters.sh 79 for example.

Then run your binary in the same directory. On some systems you might have to have a blank "out" file or BOINC will error out. These should give the following results in the "out" file:

I see a problem at line 16: -O here will undo -O2 later on. It's not necessary to specify SSE2 for x86-64 because it's the default and since x87 doesn't support vectors, it's useless to specify -ftree-vectorize for x86.

May I propose this patch against make.linux?

Thanks, i'll update the release.

*edit*

The new make.linux should have this fix.

Is there any deviation allowed in point of fitness?

thx Travis for the new code release , ive just download it and im gonna start my tests!

It's time for drilling !!

Have a nice day guys!

If the last digit or two is off this is probably just due to the architecture and not a problem.

I currently use, what I believe, are the OKed optimised MW clients across my various rigs (in the flavours to suit the different CPUs).

I also have a deactivated version of the stock MW client (milkyway_0.7_windows_intelx86), which I can easily return to in the event the assimlator/validator code dumping my optimised client results. This may be for the reasons you give below.

If I return to the stock client, will I need to download a new windows stock client (in the light of your comments on header identification and source code?

If I do, where can I get it?

Changes in the last two digits should be fine, that's just an architecture issue. Any more than that i'd start to get worried.

Dave should be updating the windows app today to v12. There should be a v10 available on the server.

Thanks, Travis. I will download V12 as soon as it is referred to, but will back it up with V10. I think we will be reverting to the stock client until new optimised clients conforming to your requirements are released. Your assimlator/validator script is likely to make all the current opti-client stock obsolete.

I've added the set_parameters.sh to automate this, just run ./set_parameters.sh 79 for example.

I've been having terrible trouble with fitness results from my app.
Speedimic suggested deleting all files produced by running the app against the test WUs and that has corrected my fitness.

So, i've amended set_parameters.sh to be

rm -f boinc_finish_called
rm -f init_data.xml
rm -f astronomy_checkpoint
rm -f out
rm -f stderr.txt

cp stars-$1.txt stars.txt
cp astronomy_parameters-$1.txt astronomy_parameters.txt
cp search_parameters-$1.txt search_parameters.txt


that takes care of things automatically

Good idea, I've updated the set_parameters.sh for the next release. One thing to watch out for is that some clients (for whatever reason) require a blank out.sh file, so I've made it:

rm -f boinc_finish_called
rm -f init_data.xml
rm -f astronomy_checkpoint
rm -f out
rm -f stderr.txt
touch out

cp stars-$1.txt stars.txt
cp astronomy_parameters-$1.txt astronomy_parameters.txt
