| Shallow clones (latest snapshot, no history) from https://github.com/orgs/vortexgpgpu/repositories, 2026-08-10. | |
| Vortex is Georgia Tech's RISC-V-based open-source GPGPU — full RTL, testbenches, | |
| compiler, and drivers all public. v3.0 (June 2026) added a 3D graphics pipeline, | |
| Vulkan driver, tensor cores, and ASIC synthesis flows. | |
| | Repo | Size | What it is | | |
| |---|---|---| | |
| | `vortex/` | 333M | **The main repo — RTL is in `vortex/hw/rtl/` (SystemVerilog).** Runtime (`runtime/`), simulator drivers (`sim/`), docs (`docs/`), tests. Cloned with submodules | | |
| | `vortex_tutorials/` | 462M | MICRO/ISCA tutorial slides and hands-on exercises — best learning path | | |
| | `skybox/` | 271M | Vortex Graphics research (Skybox) — the 3D pipeline work that fed v3.0 | | |
| | `Volt/` | 792K | VOLT — their open GPU compiler project | | |
| | `pocl/` | 56M | POCL fork — OpenCL runtime with Vortex device support | | |
| Skipped (build dependencies, multi-GB — clone only if building the full stack): | |
| `llvm` (2.3GB compiler fork), `vortex-toolchain-prebuilt` (17.6GB binaries), | |
| `mesa` (440M Vulkan driver fork), HIP-path forks (`chipStar`, `HIPCC`, | |
| `ROCm-Device-Libs`), `NVPTX-SPIRV-Translator`. | |
| ## Where to start reading RTL | |
| - `vortex/hw/rtl/VX_define.vh` — architecture parameters | |
| - `vortex/hw/rtl/core/` — the SIMT core: fetch, warp scheduler, execute units | |
| - `vortex/hw/rtl/cache/` — cache subsystem | |
| - `vortex/docs/` — microarchitecture documentation | |
| - Compare with tiny-gpu: same concepts (warps, SIMT, memory coalescing), real scale. | |
| To actually build/run: follow `vortex/README.md` (needs the llvm toolchain — | |
| prebuilt binaries download during `./ci/install_dependencies.sh` setup). | |
