Workshop on Batched,
Reproducible, and Reduced Precision BLAS
February 23-25, 2017
last
updated: 2/26/17 5:58 PM
This
workshop will touch on extending the Basic Linear Algebra Software Library
(BLAS). The existing BLAS have proven to be very effective in assisting
portable, efficient software for sequential and some of the current class of
high-performance computers. We would like to investigate the possibility of
extending the currently accepted standards to provide greater parallelism for small size operations,
reproducibility, and reduced precision support. This is the second
workshop of an open forum to discuss and formalize details related to batched,
reproducible, and reduced precision BLAS. The agenda and the talks from the
first workshop can be found here: http://bit.ly/Batch-BLAS-2016
The
purpose of the workshop is to consider defining a standard interface for the
Batched BLAS, Reproducible BLAS, and Reduced Precision BLAS. While these
are separate issues we will have presentations and
discussions on the need and issues related to these topics.
Workshop Format:
We
will start the workshop at 9:00 am on Friday, February 24th and plan to finish
around 4:00 pm on Saturday, February 25th. The structure will be for the vendors to describe what they have in
terms of hardware and mathematical software for their HPC systems, various
reports from hardware and software vendors and developers on what they need in
terms of numerical linear algebra software for todayÕs and future systems. The
authors of the Batched, Reproducible, and Reduced Precision BLAS will present
the current proposal and various implements (reference and more specific ones).
We will have discussion on various aspects of the plans.
Workshop
Location:
The workshop will be held in Atlanta on the GATech
campus in the Klaus Building room 1116E on February 24th (Friday) and 25th
(Saturday) before the SIAM CSE meeting which will be in Atlanta (February
27th-March 3rd).

From the GATech Hotel walk down 5th
St NW. You will see the Klaus Building. Walk up the steps and continue, the
entrance is on the right by the green area. Walk into the building and 1116E is
on this floor on the left.

Atlanta's mass transit, MARTA, has $1 extra fee
for paper tickets. People staying for SIAM CSE or other purposes may find the http://www.itsmarta.com/how-to-guide.aspx $2 reload-able MARTA Breeze Card to be a better value. The
cards should be available at the airport MARTA station from a vending machine.
The Breeze Card changed last year, so older ones may not function. Ride-sharing
services like Uber and Lyft also operate in Atlanta and can pick up at the
airport.
