Applications and their challenges on Blue Waters
The leadership class Blue Waters system is providing petascale level computational and I/O capabilities to its partners. To date there are approximately 32 teams using Blue Waters to pursue their science and engineering on 22,640 Cray XE CPU compute nodes and 4,224 Cray XK GPU nodes with a 26 PB, 1 TB/s filesystem. The challenges encountered by the teams are as varied as the applications running on Blue Waters. This talk will provide an overview of the Blue Waters system, its recent upgrade in GPU computing capability and network dimension, and a discussion of the
applications and their challenges computing at scale on Blue Waters.

The Navier-Stokes equations are the fundamental bases of many computational fluid dynamics problems. In this presentation, we will talk about a hybrid multicore/GPU solver for the incompressible Navier-Stokes equations with constant coefficients, discretized by the finite difference method. We use the prediction-projection method which transforms the Navier-Stokes problem into Helmholtz-like and Poisson problems. Efficient solvers for the two subproblems will be presented with implementations which take advantages of GPU accelerators. We will also provide numerical experiments on a current hybrid machine.
We will present our last result on the SMPI/SimGrid framework. SMPI now implements all the collective algorithms and selection logics of both OpenMPI and MPICH and even a few other collective algorithms from Star MPI. Together with a flexible network model and topology description mechanisme, this allowed us to obtain almost perfect prediction of NASPB and BigDFT on Ethernet/TCP based clusters. We are currently working on extending this work to other kind of networks as well as on mixing the emulation capability of SMPI with the trace replay mechanism. We are also working on improving the replay mechanism so that it handles seamlessly classical trace formats.
