<p class=MsoNormal><font size=2 face=Arial><span style='font-size:11.0pt;
font-family:Arial'>There are many approaches to exploiting multi-cores, but a
particularly promising one is the "data-parallel" paradigm, because
it combines massive parallelism (on both shared and distributed memory) with a
simple, single-control-flow programming model. Indeed, I think that data
parallelism is the only way we will be able to exploit tens or hundreds of
processors effectively.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:11.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:11.0pt;
font-family:Arial'>Alas, data-parallel programming is usually restricted to
"flat" data parallelism, which is good for implementers but bad for
programmers. Instead, I'll describe the "nested" data parallel
programming model, first developed in the 90's by Blelloch and Sabot. It is
great for programmers but much harder to implement; as a result, it's virtually
unknown in practice. It's really only feasible to support nested data
parallelism in a purely functional language, so we are building a
high-performance implementation in Haskell.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:11.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:11.0pt;
font-family:Arial'>In this talk I'll explain what nested data parallelism is,
why it's important, and what progress we have made. Fear not: I won't assume
you know any Haskell. Yet.<o:p></o:p></span></font></p>
