The company has decided to drop the support for 32-bit Linux-x86 CUDA
NVIDIA has announced that it has dropped support for the 32-bit Linux-x86 CUDA and OpenCL applications.Removing the 32-bit support is not really a problem for Linux users, given the fact that there are very few people who are still running 32-bit systems with the new Nvidia cards.
According to the company, the Linux-x86 version of the CUDA toolkit is still available and supported today, but future versions might not feature 32-bit support.
Also, the CUDA driver might not be included in future releases of the NVIDIA Linux-x86 and Linux-x86_64 GPU driver packages.
The announcement was made on the official NVIDIA dev forums and it shows that the hardware industry is no longer interested in supporting the 32-bit architecture. It's a given that the software developers will follow soon.
