The serial interface with a variable bitrate allows the SledgeHammer to attain a data transfer rate of 3.2 GB/s - in both directions simultaneously. This results in a total bandwidth of 6.4 GB/s. By comparison, the Pentium 4 with 533 MHz FSB allows a maximum data throughput of 3.97 GB/s - but not in both directions simultaneously. The bandwidth of the serial interface is designed to be flexible. AMD gives the server version of the Hammer three HyperTransport ports. The entire data traffic of the Hammer processor runs through the HyperTransport interface and the integrated memory controller. In order to let the neighboring CPU gain direct access to its system memory, the Hammer uses the XBAR switch. For commands and addresses, the XBAR switch has further 64-bit buses available. </blockquote> I thought that the processor could move more per cycle, like the difference between the 486 sx and dx. > Also, neither the PPC 970 or AMD FX are available for laptops and probably > won\'t be for quite some time.

I find it hard to believe that the ability to move twice as much information in one pass wouldnt help the ability to create and redraw the screen, and build an audio sample in shorter time. Doesnt the ability to move 64 bits into a register and perform manipulations to each set of 32 bits whilst there, improve on moving 32 bits into registers, processing, moving out, moving another 32 bits in, processing, moving out? -thewade

install notes pdp_pidip_OSX.3
by sara kolster 25 Dec '03

25 Dec '03

Hi all, I've uploaded my install-notes for pdp_pidip_osx.3. I would like you to have a look at it, so i can add / change the notes if needed. I'm still a beginner, so it could be that there are some faults in there.. Would like to hear your comments. This is the link: http://www.umatic.nl/pdp_install.html Yves; Yes, the videofile was distorted. I'll have a look at it later and try to upload it to you. Is there a way to record the video-output?

Hi > > yes, sure, when installing as root, > you need then to give read/write/excution rights > to the other users with a command like : > > sudo chmod -R 777 pdp_pidip_osx > > ( this gives all permissions ) > If i'm in pd and click on bang, a panel opens which shows all my 'normal' files, but not the /usr/ tree. Those are hidden. I'm still figuring out, if it's possible on osx3 to see all my files instead of the files that osx decided to let me see. > you should click on the bang that is before the openpanel object, > it should open a file dialog to let you choose a movie > ( a photo-jpeg one ), then you should click on play and a window > should appear ... > as rob said , it might be minimized at first , you'll only be able > to see a small icon then you should resize it > ( a silly thing in apple's X11 server, i think ). I'm able to open a quicktime, but then it shows this: pdp_qt: opening /Volumes/bospeen/FCP/schrijf.mov pdp_qt: video stream found (180x144 pixels, 25 fps, 1747 frames, rpza codec) pdp_qt: using colormodel RGB888 pdp_qt: /Volumes/bospeen/FCP/schrijf.mov opened pd_gui: pd process exited /Applications/Pd.command: line 3: 830 Segmentation fault /usr/local/bin/pd -rt logout [Process completed] And, is it normal that the cursor in my terminal-window is still moving down? Is it trying to load something, or is it just a 'time-consuming-thingy'? Thanx for your help again. Sara

overriding gsl error
by sara kolster 24 Dec '03

24 Dec '03

Hi, Due to x11 problems, i updated to OSX.3 [panther] and installed the apple X11 plus X11SDK and made it being recognized by Fink. And repeated the rest of the installation of the libs and pd[p] pidip. I get the following output when i start pd[p]: PDP: pure data packet PDP: version 0.12.1 tried /usr/local/lib/pd/pdp_pidip_osx/pdp.pd_darwin and succeeded PDP: pure data packet PDP: version 0.12.1 pdp_matrix_setup: WARNING: overriding gsl error handler. PiDiP : additional video processing objects for PDP : version 0.12.10 ( ydegoyon(a)free.fr ) Is this pdp_matrix_setup: WARNING: something familiar to anyone of you? Is this 'ignorable' or not? Sara

Hallo, (please reply to pd-list) postmeister(a)amoxi-wolff.de hat gesagt: // postmeister(a)amoxi-wolff.de wrote: > thats real great > thanks for this > but you included the math externals > is there a reason for this > cyclone is also for linux or am i wrong Cyclone also is for Linux, yes. It really would be more simple to exclude externals from loading, if sigpack would consist of single externals instead of a library. Then one simply could delete or move away all dupe externals, instead of having to recompile the lib. ciao -- Frank Barknecht _ ______footils.org__

[ANN] linux dmx external
by CK 23 Dec '03

23 Dec '03

hi, After having it running for a few days I think it's reasonably ok to share with the rest of you, there is now an extern to talk to the dmx4linux driver (-> http://llg.cubic.org/dmx4linux/ ) from pd. I wrote it for an installation (the same reason I wrote the netreceive patch), it's neither full featured nor especially well tested but it could serve as a starting point to use dmx with pd running linux. get it here -> http://test.pilot.fm/pd/externs/ more info on dmx can be found here -> http://www.euro-pa.be/dmx.html special thanks to Michael Stickel, for writing the linux driver and his kind support. ah yes and there is an exceptionally boring screenshot, but since it's there anyway -> http://test.pilot.fm/nolink/help_dmx_pd.png regards, x -- chris(a)lo-res.org Postmodernism is german romanticism with better http://pilot.fm/ special effects.

hi list, how do i get pdp (and after that pidip) from sourceforge CVS ? if i try: cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/pure-data/externals co pdp i get: cvs checkout: authorization failed: server cvs.sourceforge.net rejected access to /cvsroot/pure-data/externals for user anonymous cvs checkout-: used empty password; try "cvs login" with a real password for pd i didn't need a password. is there really a password for pdp, or did i do something wrong ? cheers -andre
