Calling CUDA from Go without cgo

TL;DR · WeSearch summary

Go is widely used for backend infrastructure but traditionally struggles with GPU programming, which is dominated by Python libraries like PyTorch and TensorFlow. A new approach allows Go to interface with NVIDIA's CUDA using the Driver API loaded at runtime, avoiding the need for cgo. This enables Go applications to directly leverage GPU capabilities without build-time dependencies on C toolchains or CUDA libraries.

Key facts

▪Go applications can now access CUDA through the Driver API loaded dynamically at runtime.
▪This method eliminates the need for cgo, allowing CGO_ENABLED=0 builds and simplifying deployment.
▪By loading CUDA libraries at runtime, Go binaries remain lightweight and portable while still supporting GPU operations.
▪The approach supports initializing CUDA, loading PTX modules, and launching kernels directly from Go code.
▪This technique benefits AI, analytics, and high-throughput data processing workloads requiring GPU acceleration.

It gives us fast builds, simple deployment, lightweight concurrency, and the ability to ship a single binary. But Go has always been awkward around one increasingly important area: GPUs. A lot of modern AI, analytics, vector processing, and high-throughput data work now runs on NVIDIA GPUs through CUDA.
