Zeta 0970 - Alpha II Release

[stevenaaus]

Yes - it seems to run ok, but I can't get it to play a tournament or give PV. All it gives is 0 0 100 0 move a1a1
I had to compile my own binary due to a glibc thing.
Tried a few hacks but i got nowhere. My box is 64 bit Linux.... havent tried windows version.

$make

$cat zeta_cl.debug

Error: Getting Platforms. (clGetPlatformsIDs)

Zeta is unable to initialize the OpenCL platform from Nvidia.

If you have the command "clinfo" on your box you could check if your "platform name" is "Nvidia"....

Some older driver have no Platform-Information, i think with OpenCL 1.1 this was introduced....

Sorry - but i don't want to debug it too much.

Thanks anyway for testing!
