I am a member of the Skulpt project and have made significant contributions to the project. Skulpt is the underlying Python interpreter for CodeSkulptor and CodeSkulptor3.
We developed Owl, an embedded Python run-time system for 32-bit microcontrollers. The overall system is described in our research paper “Design and Implementation of an Embedded Python Run-Time System”.
The code that we proposed to fix a scheduler bug in our research paper “Scheduling I/O in Virtual Machine Monitors” was adapted and implemented within Linux 2.6.39.
The connection-level parallelism strategies described in our research paper “An Evaluation of Network Stack Parallelization Strategies in Modern Operating Systems” were adapted and implemented within FreeBSD 9.0.
We developed Quicksilver. which implements a novel transparent superpage management design based on FreeBSD. Quicksilver supports both anonymous and file-backed superpages. The overall system is described in our research paper “A Comprehensive Analysis of Superpage Management Mechanisms and Policies”.
We developed Virtflex, a multi-layered system that allows the Xen hypervisor to dynamically change the NUMA topologies of its guest virtual machines. The system allows unmodified OpenMP applications running within the guests to automatically adapt to topology changes. The overall system is described in our research paper “Virtflex: Automatic Adaptation to NUMA Topology Change for OpenMP Applications”.
