Asynchronous tasks, when created with over-decomposition, enable automatic computation-
communication overlap which can substantially improve performance and scal-ability. This …

This paper reflects, from a computational perspective, on the experience gathered in
designing and implementing realtime control of the PALM-3000 adaptive optics system …

This paper describes a general algorithm and a system for load balancing sparse fluid
simulations. Automatically distributing sparse fluid simulations efficiently is challenging …

Computer systems today are becoming increasingly heterogeneous, in response to
increasingly demanding performance requirements of both traditional and emerging …

Co-designing applications and computer architectures has become of major importance due
to the growing complexity of both applications and architectures and the need to better …

This report summarizes runtime system challenges for exascale computing, that follow from
the fundamental challenges for exascale systems that have been well studied in past …

Most of the scientific problems being faced by researchers do not have embarrassingly
parallel solutions. This means that dynamic data sharing among multiple participant cores is …

High Performance Computing (HPC) is a branch of computer science dedicated to the
design and development of supercomputers and the software that runs on them. These …

In atmospheric and ocean simulation programs, stencil computations occur on semiregular
grids where subdomains of the grid are regular (ie stored in an array), but boundaries …

In various applications including atmospheric and ocean simulation programs, stencil
computations occur on grids where sub-domains of the grid are regular (eg, can be stored in …
