Workshop on Theory and Many-Cores (T&MC)
What Does Theory Have to Say About Many-Core Computing?
Friday, May 29, 2009
The sudden shift from single-processor computer systems to many-processor parallel computing systems requires reinventing much of Computer Science (CS): how to actually build and program the new parallel systems. Indeed, the programs of many mainstream computer science conferences, such as ASPLOS, DAC, ISCA, PLDI and POPL are heavily populated with papers on parallel computing and in particular on many-core computing. In contrast, the recent programs of flagship theory conferences, such as FOCS, SODA and STOC, hardly have any such paper. This low level of activity should be a concern to the theory community, for it is not clear, for example, what validity the theory of algorithms will have if the main model of computation supported by the vendors is allowed to evolve away from any studied by the theory. The low level of current activity in the theory community is not compatible with past involvement of theorists in parallel computing, and to their representation in the technical discourse. For example, 19 out of 38 participants in a December 1988 NSF-IBM Workshop on Opportunities and Constraints of Parallel Computing in IBM Almaden had theory roots. The lack of involvement of theorists should also concern vendors that build many-core computers: theorists are often the instructors of courses on algorithms and data-structures, and without their cooperation it will be difficult to introduce parallelism into the curriculum.|
The main objective of the workshop is to explore opportunities for theoretical computer science research and education in the emerging era of many-core computing, and develop understanding of the role that theory should play in it.
The workshop program includes five invited presentations, five short (10 minute) contributed presentations and a panel discussion.
