Hi all, my MacBook Pro (MBP) is running OS X 10.6.5 and Mathematica Home Edition 22.214.171.124 (32bit). It's a MBP with two graphics chips: an Nvidia GeForce 9400M and a 9600M GT -- the latter one is listed as a support chipset for Mathematica's CUDA functionality. I activated the 9600M GT chip and verified that it's the currently used one. I, too, downloaded and installed Nvidia's CUDA driver. However, I still get "False" from the CUDAQ query. I thought that's because of the missing CUDA Ressources so I tried In:= CUDAResourcesInstall but I immediately got Out= $Failed Mathematica never even tried to download that from it's paclet server -- despite the fact that I allowed Mathematica to access the Internet in the settings. So I downloaded the paclet manually (which worked). However, on a Mac, the downloaded file ends in .zip: CUDAResources-OSX-126.96.36.199.paclet.zip Now I tried several different variations of the path to this paclet in the CUDAResourcesInstall command: - gave it the full path including the zip filename - unpacked the zip file, got a folder "CUDAResources-OSX-188.8.131.52" (without the ".paclet"), and used the path to this folder - just removed the ".zip" suffix from the downloaded file and gave CUDAResources-OSX-184.108.40.206.paclet as parameter .... but none worked. :-( The "best" I got (with the last variation mentioned above) was this: In:= CUDAResourcesInstall["/Users/stefan/Downloads/CUDAResources-OSX-220.127.116.11.p= aclet"]=E2=80=A8 Message::name : "Message name "CUDAResources paclet path `1` is not valid." is not of the form symbol::name or symbol::name::language. Out= $Failed Any help on how I can install this paclet? And why doesn't the normal (automatic) installation via CUDAResourcesInstall work??? Thanks a lot! Stefan.
