I installed the CUDA toolkit by directly obeying to the WRI instructions and use MMA 220.127.116.11 as well as the paclet version 10.5.0. While CUDA's
deviceQuery sample shows an abbreviated output of
Device 0: "GeForce GTX 1070" CUDA Driver Version / Runtime Version 8.0 / 8.0 CUDA Capability Major/Minor version number: 6.1 Total amount of global memory: 8192 MBytes (8589737984 bytes) (15) Multiprocessors, (128) CUDA Cores/MP: 1920 CUDA Cores
SystemInformation only show 480 CUDA cores as can be seen here:
Does MMA count different from what Nvidia itself does or did I do something wrong while installing the package. Using both the latest CUDA drivers for macOS and the latest paclet for MMA I am quite sure the problem is not related to deprecated drivers.
