Gluon is the command processor module of the radiance GPU. This repository contains the functional simulator, driver and runtime for the Gluon command processor. It is meant to work in tandem with Cyclotron, the SIMT core functional sim. For RTL and design spec see ucb-bar/radiance repo.
- Cyclotron: Clone the cyclotron repo
Set the path to your cyclotron folder under Cargo.toml dependencies.
make <test_name> from the root automatically builds and runs the test + driver and the gluon rust server
make runs hello by default. make list prints all available tests.
cargo build and cargo run from gluon-sim/ to run just the rust server.
Let's say you want to add a test hello.
Create a dir with the name of your test under sw/test/. In this case it would be sw/test/hello.
In this dir create <test_name>_host.cpp and <test_name>_kernel.cpp. Example hello_host.cpp and hello_kernel.cpp.
Run make list to verify that make can see your test. If you added hello correctly, it should show print hello in the list.
See existing tests for the programming model. A detailed documentation of the programming model is under construction.
-
gluon-sim/: the rust functional sim that listens over a unix socket handled async with tokio. -
sw/driver/: the software driver that JIT compiles the GPU kernels and sends commands over the same unix socket configured for the rust server. -
sw/driver/test/: example test programs
See config.toml, same config is reused by the driver using toml.hpp to parse.
socket: unix socket file
