  • Dolan, Stephen; Muralidharan, Servesh; Gregg, David (Association for Computing Machinery, 2013)
    We propose a new language-neutral primitive for the LLVM compiler, which provides efficient context switching and message passing between lightweight threads of control. The primitive, called SWAPSTACK, can be used by any ...
  • Cleary, Jimmy; Callanan, Owen; Purcell, Mark; Gregg, David (Association for Computing Machinery, 2013)
    For most multi-threaded applications, data structures must be shared between threads. Ensuring thread safety on these data structures incurs overhead in the form of locking and other synchronization mechanisms. Where data ...
  • Muralidharan, Servesh; Vasudevan, Aravind; Malik, Avinash; Gregg, David (IEEE Computer Society, 2013)
    In this article we propose a novel framework – Heterogeneous Multiconstraint Application Partitioner (HMAP) for exploiting parallelism on heterogeneous High performance computing (HPC) architectures. Given a heterogeneous ...
  • Bachir, Mounira; Touati, Sid-Ahmed-Ali; Brault, Frederic; Gregg, David; Cohen, Albert (Springer, 2013)
    We address the problem of generating compact code from software pipelined loops. Although software pipelining is a powerful technique to extract fine-grain parallelism, it generates lifetime intervals spanning multiple ...
  • Nash, Nicholas; Gregg, David (Elsevier, 2010)
    We present an output sensitive algorithm for computing a maximum independent set of an unweighted circle graph. Our algorithm requires O(n min{d, α}) time at worst, for an n vertex circle graph where α is the independence ...
  • Biggar, Paul; de Vries, Edsko; Gregg, David (Elsevier, 2012)
    Although scripting languages have become very popular, even mature scripting language implementations remain interpreted. Several compilers and reimplementations have been attempted, generally focusing on performance. Based ...
  • Purcell, Mark; Vasudevan, Aravind; Gregg, David (IEEE Computer Society, 2012)
    Understanding the baseline underwater acoustic signature of an offshore location is a necessary, early step in formulating an environmental impact assessment of wave energy conversion devices. But in order to even begin ...
