Cellbuzz Projects

Postby antonlacon » 08 Feb 2009, 10:32

Has anyone started tinkering with Georgia Tech's Cellbuzz projects?

http://sourceforge.net/project/showfile ... _id=191145

The zlib enhancement may prove interesting.

I don't know if I'll get around to trying any of that today, but I'm sure I and others would be interested in any findings. Please keep us posted. :mrgreen:

mpeg2cell looks pretty neat. I might try and see if I can get them to work. Oh and using SPE's for compression? Madness I tell you!

Just a quick note; you need Cell SDK 3.0 or higher installed to compile the programs. I thought YDL came with it already but I guess I was wrong. Can anyone write a quick howto to install it? I have tried it myself but to no success using a tutorial here on this site.

There was a project to integrate a cell based mpeg2 decoder into ffmpeg released last November. I haven't had the opportunity to try it yet.

I heard about it when it started and could never get it to build successfully because of not being able to install the Cell SDK. Sure would be good to watch Iron Man in 720p......

It's in these forums somewhere - something about downloading an iso from an IPM site and then installing the missing items from the cell sdk. Note that the upgrade to ydl-6.1 maybe broke it, I'm not at a ps3 to check.

Edit: to make that clearer - I had the cell sdk-3.0 working on ydl-6.0 using the instructions in this forum. I guess the upgrade to ydl-6.1 has broken this so I'm currently downloading the cell sdk-3.1 with a view to installing it...

cellbuzz apps

Postby juanito » 13 Feb 2009, 12:29

I know there was a post about this and I wanted to add this to the thread, but no way to find the original post so...

After removing the cell sdk-3.0 (installed under ydl-6.0) and installing the cell sdk-3.1 under ydl-6.1, I downloaded a couple of the cellbuzz apps from here http://sourceforge.net/projects/cellbuzz,
Cell Broadband Engine Processor optimized libraries and software from Georgia Tech, for a number of libraries for FFT, MPEG, compression, and encryption. This project also includes patches to accelerate R on the Cell Broadband Engine processor.


The trick to compiling the apps (zlib in this case) seems to be :
$ export CELL_TOP=/opt/cell/sdk
$ make


Then from the build directory:
Code: Select all
$ echo $PWD
~/source/cellbuzz-zlib-2.0
$ example/ppu/minigzip ~/compact_flash
$ ls  ~/compact_flash*
~/compact_flash.gz


..and, as some kind of a test:
Code: Select all
 $ time example/ppu/minigzip ~/source/CellSDK-Devel-RHEL_3.0.0.1.0.iso

real    0m10.662s
user    0m0.192s
sys     0m3.327s

$ time gzip ~/source/CellSDK-Devel-RHEL_3.0.0.1.0.iso

real    0m34.130s
user    0m28.311s
sys     0m2.767s

That topic (and a few others) was moved to the new "Software Development" forum in the "Discussion" group, but I hadn't set the permissions correctly on it apparently. Please let me know if you have trouble seeing and/or posting to the new forum now.

viewforum.php?f=29

EDIT: I believe the problem is fixed now, so I'm merging this post with the original topic.
