Objectives
RISC-V is an open instruction set standard which is experiencing extraordinary growth all over the world in numerous areas of focus ranging from HPC & ML to the data center to embedded computing. The standardization activities are community driven by expert members (from industry, academia and individuals). BSC is one of the community members that is contributing to the ecosystem. This course is an opportunity to get familiar with technical aspects of the standard through a combination of lectures and hands-on sessions.
This course identifies topics that are both fundamental to computer architecture and relevant to the design of RISC-V based solutions of the future. The emphasis is always on insights that will be useful to the (under)graduate student, whether he/she goes on for a PhD or joins a software or hardware development team. We will deal with principles, trade-offs, and implementation details related to the RISC-V standard. Along the course, the students will get familiar with some layers of the RISC-V software and hardware stacks using a learning-by-doing methodology. This will provide a mechanism to the students to understand the RISC-V ecosystem, BSC know-how and activities related to RISC-V, and explore the potential of the ISA to freely develop new technologies..
Topics will cover aspects like: how to boot an operating system, how to deploy a container and execute an application, how to tune an algorithm for improving its performance through the addition of custom instructions, and finally, how to improve the performance of an HPC application by taking advantage of the RISC-V Vector extension.
Requirements
Prerequisites: Being familiar with the installation of a VMN, basic skills in C/C++ programming language, basic understanding of assembly. Some experience with QEMU is a plus, but not required. Students need to bring their own laptop for the practical sessions.
Learning Outcomes
Participants will get familiar with basic concepts in RISC-V ISA and its extensions; learn about the RISC-V ecosystem, focused on the open-source stack, going through software and hardware layers. Afterward, they will be directed to self-guided HPC challenges covering basic data parallelism and vector computation.
More precisely, the course will cover:
- RISC-V Fundamentals and ecosystem.
- RISC-V activities at BSC
- Identifying particularities of the booting process in RISC-V
- Learning how to boot an OS on a RISC-V architecture (reset vector, bootrom, firmware OpenSBI, and differences between Machine, Supervisor and User mode, basic I/O (uart, Pmem)
- Virtualization with RISC-V using TensorFlow and OpenStack
- Designing and implementing new RISC-V instructions (custom instructions) as an opportunity for optimizing a solution
- Understanding the difference between emulating (QEMU) and simulating (Gem5) a RISC-V architecture
- Understanding the popular RVV (RISC-V Vector Extension)
- Exploiting data-level parallelism using vector computation (RVV)
- Using QEMU for emulating a RISC-V platform.
