The Ultracomputer project at New York University has an immediate opening
for an experienced system software research and development person.
The Ultracomputer is an MIMD shared-memory architecture consisting
of thousands of processing elements (PEs) all accessing multiple
memory modules via a multistage interconnection network. Each PE
also has its own cache. The design is driven by
(1) the need to avoid serial bottlenecks in hardware or software,
so as to allow effective use of such a highly parallel machine; and
(2) the desire for a general and simple programming model that is not
tied to a particular algorithmic structure or data flow pattern.
Our currently running prototype consists of 8 MC68010-based PEs with caches
(to be upgraded in the next year to 68020/68881s with caches). Our operating
system is a version of UNIX (based on v7) with a kernel that is parallel
(concurrently executed by multiple PEs) and symmetric (no master/slave
relationship). Primitive but usable facilities are provided for parallel
applications. We have software instruction and address tracing facilities,
for use in architectural and operating systems research. The operating
system and software environment are being developed both for our own hardware
and for a much larger prototype, which includes the Ultracomputer
architecture plus significant extentions, being considered by IBM
Research Division at Yorktown Heights.
The job will involve research into and further development of system
software for the Ultracomputer. Specific areas include:
further elimination of serial bottlenecks in the kernel
design of new critical-section-free algorithms and data structures
improved operating system support for parallel applications
parallel languages and tools for parallel application development
parallel debuggers
upgrading to 4.2BSD
support for newer prototype hardware
performance evaluation, monitoring
enhancement of monitoring facilities
operating system testing
hardware diagnostics
general software support
We are part of the Courant Institute of Mathematical Sciences,
located in Greenwich Village, New York City. Salary is competitive
and NYU benefits are excellent (including four weeks annual vacation
and tuition remission). NYU is an equal opportunity affirmative
action employer.
