Broadly, I am
interested in large-scale parallelism in computer systems and its
implications on application performance, operating system design, fault
tolerance and big data in cloud computing. My particular interests focus on
secondary memory system technologies and optimization, scalable file and
key-value storage systems, scalable machine learning and systematic testing
for large scale systems. I have a strong interest in shepherding technological advances from blackboard through standards and to commercial reality .
I joined the faculty
of CMU's Computer Science Department in 1991. Previously I received a
Ph.D. and a M.Sc. in Computer Science in 1991 and 1987, respectively,
from the University of California at Berkeley. Prior to Berkeley, I received
a Bachelor of Mathematics in Computer Science and Applied Mathematics
in 1983 from the University of Waterloo in Ontario, Canada.
In 1993 I founded CMU's
Parallel Data Laboratory (PDL)
and led it until April 1999.
Today the PDL is led by Greg Ganger. The PDL is a community that typically comprises
between 3 to 6 faculty, 1 to 2 dozen students and 4 to 10 staff. It
receives support and guidance from a consortium of 10 to 20 companies
with interests in storage systems, the Parallel Data Consortium.
This community holds biannual retreats
and workshops to exchange technology ideas, analysis and future directions.
The publications of the PDL are
available for your inspection.
The principal contributions
of my first twenty years of research: Redundant Arrays of Inexpensive
Disks (RAID), Informed Prefetching
and Caching (TIP) and Network-Attached Secure
Disks (NASD), now an ANSI SCSI command set standard (OSD), have all stimulated derivative
research and development in academia and industry. RAID, in particular,
is now the organizing concept of a 10+ billion-dollar marketplace (more
on RAID in my 1995 RAID tutorial).
In 1999 I started Panasas Inc., a scalable storage cluster company using an object storage architecture and providing 100s of TB of high-performance storage in a single management domain for national laboratory, energy sector, auto/aero-design, life sciences, financial modeling, digital animation, and engineering design markets.
In 2006 I founded a Petascale Data Storage Institute (PDSI) for the Department of Energy's Scientific Discovery through Advanced Computing (SciDAC). Led by CMU, with partners at Los Alamos, Sandia, Oak Ridge, Pacific Northwest and Lawrence Berkeley National Labs, and University of California, Santa Cruz and University of Michigan, Ann Arbor, this Institute gathers together leading experts in leadership class supercomputing storage systems to address the challenges involved in moving from today's terascale computers to the petascale computers of the next decade.
In 2008 I turned to Data Intensive Scalable Computing, Clouds, and Scalable Analytics, participating in the design and installation of 2 TF, 2TB, 1/2PB of computing in an OpenCirrus and an OpenCloud cluster.

- PLFS (see SC09 paper below and institutes.lanl.gov/plfs) has been released on Sourceforge (sourceforge.net/projects/plfs) under a BSD license. It is available through MPI-IO libraries or FUSE user level file system reflector. It is being put into production HPC use at Los Alamos.
- pNFS, or Parallel NFS, is a subset of the new features in NFS version 4.1 (www.pnfs.com, RFC 5661-5664, tools.ietf.org/html/rfc566x for x=1,2,3,4). pNFS hails from a workshop in Dec 2003 when Garth Gibson and Peter Honeyman asked "what is next for NFS" and Gibson/CMU/Panasas answered: delegation of file layouts (direct and indirect pointers in an inode, sort of). Based on the NASD file system work (ASPLOS98 below) that inspired Panasas (FAST08 below), pNFS allows client machines to request a (revocable) map of the locations of data in a storage area network (seen as SCSI blocks, SCSI objects or NFS files) which the client can use to directly access file data (without access being proxied by the NFSv4.1 server).
- an implementation of pNFS built on top of NFS files was taken into Linux in 2.6.39
- an implementation of pNFS built on top of SCSI objects was taken into Linux in 2.6.40, renamed as 3.0
- an implementation of pNFS built on top of SCSI blocks was taken into Linux 3.1
- extension of pNFS built on SCSI objects with RAID 1 and RAID 5 over objects on different data servers, taken into Linux 3.2
- Past member of the
technical council of the Storage Networking Industry Association
(SNIA), an international organization
of about 100 networking and storage companies formed in July 1999.
and chair, National Storage Industry Consortium (NSIC) working group
on Network-Attached Storage Devices (NASD), 1996-1999. Program chair for eleven
NSIC/NASD sponsored public workshops (75 presentations
and 500 attendees). The result of these efforts was presented in "Object
Based Storage Devices: A Command Set Proposal," (http://www.nsic.org/nasd/final.pdf,
November 1999) which was written to launch an ANSI standards effort
in the X3/T10 (SCSI) committee.
- Release of NASD Scalable Storage
Systems Prototype code, version 1.1 in July 1999, and version 1.3
in May 2000. This code implements CMU's view of the next generation
storage interface (SCSI-4?) and a simple set of changes for a distributed
file system to exploit it.
- Release of RAIDframe Rapid Prototyping Tool for
RAID Systems code, August 1996. This code, suitably debugged and
adapted, appears as the RAID device driver in the current release of
the NetBSD operating system.
