Second Workshop on Approximate Computing Across the System
Stack (WACAS)

Co-located with ASPLOS 2015
Istanbul, Turkey
March 15, 2015
Traditional computing imposes an “exactness” that is becoming both
energy expensive and unnecessary, especially so in the era of big data.
The relaxation of accuracy, and more importantly the relaxation of the
requirement of deterministic execution provide an opportunity to explore
new energy-efficient execution models to process this vast data. Recently,
the approximate computing paradigm has continued to gain importance
as a vehicle to reason about changes across the stack from algorithms to
devices to produce results that are acceptable albeit different from exact

Making approximate computing successful requires cooperation among
all layers of the stack, from algorithms to programming languages to OSes
to architecture to circuits, as well as system components like storage and
networks. This workshop aims to bring together an interdisciplinary group
of researchers to present and discuss thoughts and ideas on how to
effectively exploit approximate computing.

Topics include but are not limited to the following:
– Position papers on approximate computing: trends, potential, pitfalls
– Cross-layer approximate computing solutions
– Hardware/Software support for approximate computing
– Tools for writing, debugging, and reasoning about approximate programs
– Characterization of workloads suitable to approximation
– Methodology/Models to estimate cost/benefits of approximate computing

Peer-reviewed papers will not be published in a proceedings, so submitting
to WACAS will not preclude future publication opportunities.

Prospective authors of research papers should aim for 6 pages including

Submissions may optionally be blind: authors can choose whether to include
their names.
