### Purpose Upgrade the GPU backend to the latest NVIDIA software stack: - CUDA 12.6 - cuSPARSE 12 - cuBLAS 12 - cuDNN 9 ### What Changed **1. Dependencies:** - Removed every jcuda-apple entry from pom.xml (CUDA support for macOS ended with toolkit 10.2). - Updated jcuda 10.2.0 to version 12.6.0. **2. Code:** - Replaced or rewrote functions that used CUDA, cuSPARSE, or cuDNN APIs now deprecated or removed in the 12.x / 9.x series. ### Notes - No Apple GPU build is possible after this upgrade (CPU backend remains unaffected). - All changes were developed and tested against these exact versions: CUDA 12.6.85, cuSPARSE 12.5.4, cuBLAS 12.6.4, and cuDNN 9.10.1. - Deprecated calls were replaced strictly according to NVIDIA’s official porting guides in the documentation; the additional setup code you see (e.g., new descriptors, longer pipelines, etc.) is the expected overhead described in those documents and is therefore correct. ### Next Steps We still rely on JCuda as the Java–CUDA bridge. Now that the backend runs on the newest NVIDIA toolchain, the logical next phase is to replace JCuda with our own JNI bindings. Because JCuda itself is only a thin JNI wrapper, the migration is conceptually straightforward—essentially re-exposing the functions we actually use—but it will take time to: - Generate a minimal JNI layer for the required CUDA / cuSPARSE / cuBLAS / cuDNN calls. - Add build scripts to compile the native library on Linux and Windows. - Incrementally swap JCuda classes for the new binding with tests at every step. The payoff is full control over versioning and fewer external dependencies once the work is complete. -- This is an automated message from the Apache Git Service.
