Towards Fully-fledged GPU Multitasking via Proactive Memory Scheduling
Weihang Shen, Yinqiu Chen, Rong Chen +1
The limited HBM capacity has become the primary bottleneck for hosting an increasing number of larger-scale GPU tasks. While demand paging extends capacity via host DRAM, it incurs…

Microsecond-scale Dynamic Validation of Idempotency for GPU Kernels
Mingcong Han, Weihang Shen, Guanwen Peng +2
We discovered that a GPU kernel can have both idempotent and non-idempotent instances depending on the input. These kernels, called conditionally-idempotent, are prevalent in real-…
