This repository contains code for our work on Hydra (a user-level filesystem) and block/byte-range lock server (a user-level distributed locking framework). This work is related to our Scalable Technologies for Ultra-scale I/O project, which was supported in part by the National Science Foundation.

Downloads at this time must be fetched directly from our Subversion repository.

Fetching and Installing Hydra

The code for the Hydra filesystem can be checked out as follows

svn checkout http://st-hec.googlecode.com/svn/trunk/hydra

The build instructions are available in the Hydra README.text file, which can also be found in the top-level directory after you perform the repository checkout.

Fetching and Installing the Distributed Lockserver

svn checkout http://st-hec.googlecode.com/svn/trunk/lockserver

Please contact us if you are interested in working with this code. We have not yet written an installation document but there are proper make files (for the C portion) and Ant build files (for the Java portion). So it is possible to explore on your own.
