Software

• pssh: Parallel openssh tools, including pssh, pscp, prsync, pnuke, and pslurp. These tools can be useful for controlling and managing multiple machines in either a cluster environment or over the wide-area (e.g., on PlanetLab) . For more information, including the latest software distribution, see the pssh web page.

• GEXEC: A scalable cluster remote execution system which provides fast, RSA authenticated remote execution of parallel and distributed jobs. It uses hierarchical control and is designed to provide robust and scalable execution to systems over 1000 nodes. For more information, including the latest software distribution, see the GEXEC web page.

• PCP: A system for fast replication of files on multiple nodes of a PC cluster. Replication is done by building an n-ary tree of TCP sockets and using parallelized, pipelined data transfers which use RSA authentication. For more information, including the latest software distribution, see the PCP web page.

• authd: A software package for obtaining and verifying user credentials which contain cryptographic signatures based on RSA public key cryptography. authd is currently used as part of both PCP and GEXEC. For more information, including the latest software distribution, see the authd web page.

• libe: A C library which contains various functions which deal with data structures (hash tables, bitmasks, trees of IP addresses, etc.), networking, I/O, barriers, and other useful things. It is currently used in the implementation of authd, PCP, and GEXEC. For more information, including the latest software distribution, see the libe web page.

• dslice: Prototype dynamic slice creation implementation for PlanetLab. Users obtain cryptographically signed tickets from an agent and subsequently redeem these tickets for leases on node resources which are bound to virtual machines (currently Linux vservers). For more information, including a link to the latest software distribution, see the dslice web page.

• REXEC Cluster Remote Execution System: A decentralized, secure remote execution system for running parallel and sequential jobs on a cluster of computers. Also distributed as part of the NPACI Rocks open-source, cluster software distribution. For more information, including the latest software distribution, see the REXEC web page.

• Active Messages: A fast, general-purpose cluster communication system that supports multiprogramming with virtual networks, direct and protected network access, reliable message delivery using message timeouts and retransmissions, a powerful return-to-sender error model for applications, and automatic network mapping. (Berkeley distribution)

Courses

• CS199-6: An undergraduate project course aimed at building planetary-scale applications to run over the PlanetLab infrastructure, and/or the tools and services needed to effectively deploy and manage them. Co-taught with Timothy Roscoe at UC Berkeley in Spring 2003. An archive of the course materials is here.
