Vortex Workshop and Tutorials at MICRO-58 (18th October 2025)
Description:
Vortex is an open-source hardware and software project to support GPGPU based on RISC-V ISA extensions. Currently, Vortex supports OpenCL/CUDA and it runs on FPGA. The Vortex platform is highly customizable and scalable with a complete open-source compiler, driver and runtime software stack to enable research in GPU architectures. This event includes both a workshop and tutorial. The tutorial will cover Vortex's hardware, software, applications, and provide hands-on exercises. The workshop brings together Vortex developers and researchers to discuss and present their Vortex-related research.

Provided are seven hands-on tutorial assignments covering various aspects of Vortex:
Assignment 1 and Assignment 2 add a warp efficiency performance counter in Vortex's cycle-level simulator and RTL respectively.
Assignment 3 and Assignment 4 add software prefetching to the cycle-level simulator and RTL respectively.
Assignment 5 and Assignment 6 add a new custom RISC-V instruction for computing the integer dot product in the cycle-level simulator and RTL respectively.
Assignment 7 teaches how to debug Vortex.
A terminal interface hosted by the CRNCH Rogues Gallery is provided. Instructions can be found here.
See the Docker instructions for how to set up a Docker image for Vortex.
If you would like to set up Vortex on your own system, instructions can be found here.
