EECS 582 Final Project

Yong Seung Lee (leeyongs), Johnathan Schwartz (johnschw), Alan Yang (alanyang)

Requirements

1. ghOSt kernel must be installed.
2. Follow the directions in ghOSt userspace to install the necessary headers and to install Bazel (the build tool used for the project).
3. Run bazel build -c opt ... to build all ghOSt userspace components, including our Orca components.

Running the project

You can run the experiments from our paper by running scripts/run_simple_workload_exp.sh.

Our changes

This repo is a fork of the ghOSt userspace libraries.

Here is a rough list of changes which we made as part of our project:

1. Added orca directory, which includes the Orchestrator code.
2. Added plot and stats directories, which include scripts for generating the graphs from our report.
3. Added instrumentation code to the provided schedulers/fifo/centralized and schedulers/fifo/per_cpu ghOSt userspace schedulers.
4. Added scripts directory, which includes scripts we wrote during development.
5. Added tests/custom/simple_workload.cc, which represents the synthetic workload we ran experiments on.
6. Changed Bazel BUILD file to include all of our code when compiling the library.
