Hardware acceleration for unikernels

Applications demand fast and secure execution in diverse environments (Cloud data centers, Edge Nodes, mobile platforms etc.). Execution efficiency has been facilitated by the introduction of specialized compute elements (eg. GPUs), in order to accelerate specific parts of tasks/workloads (such is image processing). At the same time, too abstract deployment and management burdens, service providers use virtualization and container technologies. Eliminating the software overheads of these abstractions, especially in the context of hardware off-load/acceleration is a challenge and requires a number of factors to be taken into consideration: (a) portability, (b) performance, and (c) security. In this talk, we attack the first two factors and examine the option of unikernels and their surrounding ecosystem (application porting frameworks, orchestration frameworks, lightweight virtualization backends) in the context of hardware acceleration. We present our efforts in porting a novel hardware acceleration framework, vAccel, to the rumprun unikernel, digging into the internals of semantic abstraction for ML inference, as well as its implementation on rumprun and QEMU/KVM. We describe the frontend/backend driver port, the runtime needed to support the actual execution on the hardware and showcase our results in a brief demo of two unikernel frameworks performing ML inference on images.

I will provide an update on developments in the seL4 ecosystem in the past 12 months. Highlights include the creation of the seL4 Foundation and some of its activities since, and the functional correctness proof of seL4 on the RISC-V architecture. I will also discuss our work on time protection, a principled and systematic approach to prevention of timing channels and on-going work on its formal verification.

The seL4 Foundation was created in April 2020 as a Project of the Linux Foundation. Its aim is to provide an open and neutral framework for developing seL4 and its ecosystem and promote update. The talk will give an overview of the seL4 Foundation, its goals and activities and the benefits of joining.

Microkernels, partial virtual machines and internet of threads are not unrelated. The challenge of this talk is to show that the new libioth providing an effective and flexible support for the internet of threads can open interesting perspectives for a wider range of applications.

Resilience is often touted as the biggest advantage of component-based systems over monolithic architectures. The catchy part of the story often told is the containment of faults via sandboxing. However, the story has another inconvenient side that often remains untold. Components are interdependent. Whenever a central low-level component fails, dependent software stacks suffer under the outage. The talk presents Genode's recent breakthroughs to address this second part of the story, in ...

In this talk we give an update on the Unikraft Linux Foundation open source project, a fully modular and librarized unikernel that aims to provide outstanding performance while making it easy to port off-the-shelf applications into unikernels. In particular, we will go into details how Unikraft (1) fully modularizes OS primitives so that it is easy to customize the unikernel and include only relevant components, (2) exposes a set of composable, performance-oriented APIs in order to make it easy ...
