Globally Scheduled Real-Time Multiprocessor Systems with GPUs
 

Summary: Globally Scheduled Real-Time
Multiprocessor Systems with GPUs

Abstract
Graphics processing units, GPUs, are powerful pro-
cessors that can offer significant performance advantages
over traditional CPUs. The last decade has seen rapid
advancement in GPU computational power and general-
ity. Recent technologies make it possible to use GPUs
as co-processors to the CPU. The performance advan-
tages of GPUs can be great, often outperforming tradi-
tional CPUs by orders of magnitude. While the motiva-
tions for developing systems with GPUs are clear, little
research in the real-time systems field has been done to in-
tegrate GPUs into real-time multiprocessor systems. We
present two real-time analysis methods, addressing real-
world platform constraints, for such an integration into
a soft real-time multiprocessor system and show that a
GPU can be exploited to achieve greater levels of total
