I have 2 Thunder II GX cards and one ThunderStorm DSP card. All this cards have two AT&T DSP 16A chips.
I tried to run all 6 processors at the same time but that doesn't work. Mac use only the first card that is installed nearest to the PSU and use only that one. The ImageProccessor control panel identifies all cards and processors installed but only first card is used.
The cards were installed in my Quadra 950, 256 RAM, 2x 2 GB HD drive, like this
Slot A - Radius PrecisionColor 24x
Slot B - Thunder II GX
Slot C - Thunder II GX
Slot D - ThunderStorm
Slot E - JackHammer
PSU
Tested it with PicturePress 2.5 and Photoshop 2.0.1. The Thunder II GX cards were for few seconds faster than the ThunderStorm DSP card.
Without hardware acceleration PicturePress opened sample ship file in 5.6 secs. When used DSP cards the ThunderStorm opened the same file in 1.8 sec, and the Thunder II GX in 1.5 seconds.
When using Photoshop and Gaussian blur at 10 px, the StormCard used 14 sec, Thunder 12 sec.
This was just a quick test to se if the Mac can use all DSP processors at the same time, but as I said that is a no go
