You are doing a great job :)

If anyone could make the port to Linux possible then Crunch3r would be the one to do it!

We are not expert ( at the moment :) ) On compilators and how they work, so we are learning from the work of others ( like Sesef).

We think that there is a problem with the class __md128 and the system. We have workaround that and it could be a conflict between this class and the linux system one that have the same name.

We are using the code directly from Sesef which can be found here: https://github.com/sesef/denis-boinc-baseapp

We are also working on the new version with multimodel support.

Best regards, Joel.

OK.. Here's the code and binary for 64 bit linux SSE2.
(copy&paste the link to download otherwise you'll get an error message)

http://www.boincunited.org/opt_apps/DENIS@Home_Linux_x64.tar.bz2

Instead of using Intels SVML, i've used the free of charge "amd libm"
(http://developer.amd.com/tools-and-sdks/cpu-development/libm/)
see "simd.h"

Hope that helps ;)

EDIT:
If there's a need for an OSX app, i can compile that as well.
(However, the linux code should compile straight forward on OSX using g++ > 4.5)

Great!

If it is ready for crunching I will run it in one of my linux boxes..

Thank you!

Thanks Crunch3r!

As a new user with Kubuntu, how can i put this app in project?
Can´t even access project folder in /var. Can i use a command to move and run this app?

Thanks for providing Linux binaries Crunch3r!

@47an: Here's how you get the app running:

1. Open up a terminal
2. Change to the directory where you downloaded and extracted the files (If not extracted yet, use

tar xfvj DENIS@Home_Linux_x64.tar.bz2

after cd to the download directory)

$ cd /home/$USER/Downloads

3. Open a root shell to be able to access the BOINC data directory

$ sudo -s

4. Move the files to your BOINC data directory

# mv DENIS@Home_Linux_x64/binary/* /var/lib/boinc-client/projects/denis.usj.es_denisathome/

5. Change owner of files to user and group boinc to enable access for BOINC

# chown -R boinc:boinc /var/lib/boinc-client/projects/denis.usj.es_denisathome

6. Restart BOINC

# /etc/init.d/boinc-client restart

7. Exit the shell

# exit

$ exit

Perfect, that was the commands i needed. Thanks m4gu5 for the guide.

OK...
here's another on that's truely cross platform compatible.

I've rewritten the code once again and it will compile on Linux, OSX and Windows out of the box(when using GROMACS, see simd.h).

I've changed some simd routines backported from the CPU app over at Milkyway@home that are based on my own code.
(see -> http://rcos.rpi.edu/projects/milkywayhome/commit/separation-merge-vectorized-streams-from-crunchr/)

The app will use GROMACS vectorized versions of exp and pow now.

Besides that, you'll have the option to choose between AMD libM, Intel SVML and GROMACS code. (see simd.h and sse2_math.h)

Both Linux and OSX apps are now using the faster GROMACS code to do exponential and power functions.

Thank you so much! You have no idea how happy I am that I don't have to switch back to Windows! :P

Impressive job! When I start in this project I couldn't imagine a community as well as this one. You are awesome, thank you so much.

We will work with this one and sesef's version to produce faster apps. We hope we can launch a new version soon.

Best regards, Joel.

you're welcome.
please make sure to use only the http://www.boincunited.org/opt_apps/DENIS@Home_cross_platform.tar.bz2 source code.
that one will compile on windows,linux and osx making it easier for you to develop new models ;)

New optimized apps!!!

Last month was very busy for me. I hadn't time to finish what I started in August.

Yesterday I finally finished rewrote model to perform from SSE2/SSE3 instructions and replaced Intel SVML functions with open source replacement (Logarithm form GROMACS 5.1, exponential from Herumi fmath). This is almost the same code as used by Crunch3r, exp is faster than Intel SVML, log is almost as fast as intel.


All this gives about 30% speed improvement over 1.4.1

https://github.com/sesef/denis-boinc-baseapp (updated source code)

NEW OPTOS APP
WU is currently too short.
Please longer.

All this gives about 30% speed improvement over 1.4.1

It is now over 10x as compared to the official DENIS version (Win7 64-bit, i7-4771).

Thanks a lot.

Thank you so much! You have no idea how happy I am that I don't have to switch back to Windows! :P

Glad I could help. Happy Crunching! :)

Just signed up for this project yesterday and happened to stumble across this thread. Can say that Sesef's optimized app certainly makes a big difference for me! On one quad-socket E5-4640 v1 box, the WU's went from 60-70m to ~11m. FWIW I did keep an eye on a couple WU's to be sure. BOINC was estimating they'd take about 65 minutes and they finished in just over 11.

BTW, this app helped me contribute 1M points in 24 hours. Awesome. :)

Here are the updated binaries and source code based on 1.55.

I've included binaries for Linux(64 bit) ,OSX (64 bit) and Windows (64 bit).

There are binaries for SSE2 only CPUs available as well!

If a system can support both SSE2 and SSE3 versions, is there an advantage to using one over the other? Some very quick tests on my 64 bit Linux systems show pretty much the same times for both versions (and they are about 85%-90% faster than the stock version).

Also, any chance of a 32 bit Linux version for SSE2? I've got one lone cruncher of that kind that could use some help.

If you notice, his URLs both link to the SSE3.

As a side question, do these take advantage of AVX?

The original code uses SSE3 instructions and i've decided that there's no need to exclude older sse2 capable cpus. So i've modified the code so it'll work on older cpus as well.

In about an hour i'll upload some 32 bit linux builds for sse2 & sse3 ;)
