在本文中,我们提出了第一个通用GPU热管理设计,该设计由硬件架构和操作系统调度器更改组成。我们的技术根据系统的热状态,以空间、时间和时空的方式调度来自多个计算内核的线程块。在满足热约束的情况下,我们可以将计算速度平均降低60%。我们还将我们的工作扩展到多GPGPU卡,并且相对于现有技术平均提高了44%。
In this paper, we present a first general purpose GPU thermal management design that consists of both hardware architecture and OS scheduler changes. Our techniques schedule thread blocks from multiple computational kernels in spatial, temporal, and spatio-temporal ways depending on the thermal state of the system. We can reduce the computation slowdown by 60% on average relative to the state of the art techniques while meeting the thermal constraints. We also extend our work to multi GPGPU cards and show improvements of 44% on average relative to existing technique.
