Some Open Source Code
ffmpeg360: It is a tool for rendering 360-degree videos and converting
between projection types. Operations are performed on the GPU within
a fork of the FFmpeg utility. Its GitHub repository is here. Please refer to our paper for more details.
CAD (Content Assited Displaying for Mobile Device Power Saving): CAD
for the online video calls is based on WebRTC. The implementation
utilizes the GPU on mobile devices. Its GitHub repository is
here. For more technical detail, please refer to our paper.
UMON (User Defined Monitoring for SDN based networks): UMON implements
a separate monitoring table that decouples monitoring from switching in the open vSwitches.
Its GitHub repository is here. For more technical detail, please refer to our paper.
XEN Scheduler: Cloud is subject to various side channel attacks due to
underlying sharing of the physical resources. Our new schedulers can
effectively mitigate such threats. Its GitHub repository is here. For more technical detail, please refer to our paper.
rKube: Containers are widely used in clouds, but they often fail to
deliver the anticipated performance with the allocated
resources. Our new mechanism, rKube, can
effectively address that on top of Kubernetes and Linux. Its GitHub repository is here. For more technical detail, please refer to our paper.
SFS (Smart Function Scheduler): Serverless functions are typically short and their execution may get significantly prolonged due to contentions. SFS addresses this by using two level scheduling. Its GitHub repository is here. For more technical detail, please refer to our paper.
