Managing GPUs as First-Class Operating System Resources
by Shinpei Kato, Visiting Scientist, UCSC
[ABSTRACT] The graphics processing unit (GPU) is becoming one of the most powerful platforms to support high-performance computing. Due to recent advances in programming support for general-purpose computation on GPUs, also known as GPGPU, GPUs are now used in not only graphics but also general compute domains. This talk presents Gdev, a new approach to GPU resource management in operating systems. Gdev manages GPUs as first-class operating system resources so that GPU-accelerated applications can be provided with fine-grained prioritization and isolation in multi-tasking environments. Gdev also provides a unified application programming interface for operating systems and user-space programs. This unified interface enables operating systems to launch GPU code directly, while user-space programs can also launch the same GPU code through system calls, such as "ioctl", or user-space Gdev runtime. We believe that Gdev will broaden a class of applications that benefit from GPUs and enhance the reliability of GPU computing.
