Description

The NVIDIA CUDA® Toolkit 12.6 is part of the CUDA 12.x series and includes the latest performance improvements, library updates, and expanded support for modern GPU architectures including Hopper (H100) and Ada Lovelace (RTX 40 Series).

Key updates in CUDA 12.6:

• Support for sm_90a (Hopper Next) and improved Hopper scheduling behavior

• Upgraded host and device toolchains for compatibility with newer compilers and kernels

• Updated math libraries (cuBLAS, cuSPARSE, cuSOLVER, etc.) for improved performance

• Nsight Compute 2024.x and Nsight Systems 2024.x for profiling and analysis

• Continued support for CUDA Graphs, LTO, and Cooperative Groups APIs

• Compatibility with GCC 12+ and RHEL 9+

CUDA 12.6 continues backward compatibility with Ampere, Turing, and Volta-based GPUs.
