GPU computation

[M Cluster]

Hello Cummity,

It would be very nice if the Eon2 - client 1.0 can also be used by GPU.
Is it being considered for the Eon Project is an Cuda support to programming, if so, by when this would be done?
I could add some TFlops because my GPU cluster is a cluster rather.

If no Cuda support is planned? Could the source be disclosed to me? Respectively. the community to incorporate this support?

Thank you

Regards

Or... would this application lend it itself better to the multi-thread capability of the ATI cards.

PS: Personally only interested in Linux apps.

[M Cluster]

Yes Ati would support inside. Only problem is you'd need the source code to programmers for anything.

Eon are the source to write freely about a GPU support?

These are good questions. We'll work on a multithreaded client first (perhaps using mpi). We have not found an efficient way to use GPUs yet, but there is some possibility with one of our potentials. Anyway, GPUs will not be supported any time soon.

[M Cluster]

Ok, there is a possibility to write their own clients for Eon? I may find a way for multithreading or porting to GPU computation.

What are the chemical equations calculated their files?
Is it allowed an own client to write and test this?

Regards

[graeme]

Sure, by all means. While there is quite a bit of code, the computational work is localized to a few function calls that evaluate the force and energy between the atoms. These are all in the potentials subdirectory of the client code.

[M Cluster]

Well, I look at the files in the tar at times. uncompiled version of Linux could be published clientes?
I would then begin.

We now have anonymous read-only access to our subversion repository for eon. The url is http://theory.cm.utexas.edu/svn/eon. It can be checked out like so:

svn co http://theory.cm.utexas.edu/svn/eon

Hi,

I have now started a cuda class to write.
now I have tried to compile your revision 640 without my improvement.
have generated the client file and renamed the copied project folder.
You experience the following error.
looking a what have I done wrong? standing on the hose: P

I wouldn't try to test your client the way you are doing it. It probably doesn't work because has not been built with the boinc library (by running "BOINC=1 make" in the client directory). The client also supports being compiled in a standalone mode, which is most likely what you have built. I would instead run one of the samples like in "client/samples/al". Just run the client you built in that directory after running the init script in that directory to setup the files.

Hello So I try to explain my whole steps.


1. Creating Directories

Code: Select all

cd / home
mkdir boincadm
cd boincadm

2. SVN - Download BOINC and Eon

Code: Select all

svn co http://boinc.berkeley.edu/svn/trunk/boinc

so that the BOINC source downloaded / revision currently 22 729

Code: Select all

svn co http://theory.cm.utexas.edu/svn/eon

Eon Source - Revision 645

3. present term folder structure
Dir: /home/boincadm

We now have 2 new subfolders.

1. / Home / boincadm / boinc

2. / Home / boincadm / eon

see in append
boinctree.txt
eontree.txt

4. Compiling BOINC

The following commands must be executed
We are in the folder
"/ Home / boincadm"

Code: Select all

cd boinc
. / _autosetup
. / Configure - disable-server
make

5. Compiling Eon

We must now copy the eon Boinc Libraries
boinc_api.h
diagnostics.h
filesys.h

boinc_win.h
win_util.h

Code: Select all

cp / home / boincadm / boinc / api / boinc_api.h / home / boincadm / eon / boinc / boinc_api.h
cp / home / boincadm / boinc / lib / diagnostics.h / home / boincadm / eon / boinc / diagnostics.h
cp / home / boincadm / boinc / lib / filesys.h / home / boincadm / eon / boinc / filesys.h

cp / home / boincadm / boinc / lib / boinc_win.h / home / boincadm / eon / boinc / boinc_win.h
cp / home / boincadm / boinc / lib / win_util.h / home / boincadm / eon / boinc / win_util.h

*******

we certainly need to configure the client eon
boinc config - "/ home / boincadm / eon / boinc / config.ini"

- Here I have no plan now which come in this folder
I tried several variants.

Now we compile the client Eon

Code: Select all

cd /home/boincadm/eon/client
make

6. test of client Eon

Copy the client in the test folder

Code: Select all

cp / home / boincadm / eon / client / client / home / boincadm / eon / client / samples / al / client

init files for creating the chem

Code: Select all

. Cd / home / boincadm / eon / client / samples / al
. / Init
. / Client
. / Clean

if no errors occur here is how the client



Question:

So my client is great in about 8 mb

now how do I put the configs so that the Boinc lib is used?

Code: Select all

EON client Compilation Options
BOINC: No
DEBUG: Yes
POTENTIAL: EMT + + + MORSE LJ-EAM + QSC + Pt + H2O-VASP + + + Aluminum bopfox Lenosky + SW + + Tersoff EDIP

because I get the Eon client only compiled in debug mode
He works because he expects the samples correctly.

You can compile the client with the boinc libraries by setting the environment variable BOINC to any value at all. If you use the bash shell you can build it like so:

Code: Select all

BOINC=1 make

I don't understand why you want to go to all the effort of building a boinc client and running a boinc server if your goal is to add GPU support to the client. That part has nothing to do with boinc specific apis. You should just build the client without boinc support in order to do your tests. By the way, 99% of the cpu time is spent calculating the force, which is done by the potential. Thus it probably only makes sense to move these parts to the GPU. The potential that is used is set in the parameters_passed.dat file and the code for the different potentials is in client/potentials/. The most simple potential is probably the morse or lennard jones potential.
