This modeling is performed to advance the rate of learning about optimal EUV generation for laser produced plasmas and to provide insights where experimental results are not currently available. The goal is to identify key physical processes necessary for an accurate and predictive model capable of simulating a wide range of conditions. This modeling will help to drive source performance scaling in support of the EUV Lithography roadmap. The model simulates pre-pulse laser interaction with the tin droplet and follows the droplet expansion into the main pulse target zone. Next, the interaction of the expanded droplet with the main laser pulse is simulated. We demonstrate the predictive nature of the code and provide comparison with experimental results. ALE-AMR and other codes are used for the modeling.

Accelerators have gained prominence as the next disruptive technology with a potential to provide a non-incremental jump in performance. However, the number of applications that have actually moved to accelerators is still limited because of many reasons, arguably the biggest of which is the gap in understanding between accelerator and application developers. This BoF is an application oriented session that aims to bring the two camps of application developers and accelerator developers head-to-head.

Tim Mattson, Alice Koniges, Simon McIntosh-Smith, OpenCL: A Hands-On Introduction, SC13 Tutorial, November 18, 2013,

OpenCL is an open standard for programming heterogeneous parallel computers composed of CPUs, GPUs and other processors. OpenCL consists of a framework to manipulate the host CPU and one or more compute devices (CPUs, GPUs or accelerators), and a C-based programming language for writing programs for the compute devices. Using OpenCL, a programmer can write parallel programs that harness all of the resources of a heterogeneous computer. In this hands-on tutorial, we will introduce OpenCL. For ease of learning we will focus on the easier to use C++ API, but attendees will also gain an understanding of OpenCLs C API. The format will be a 50/50 split between lectures and exercises. Students will use their own laptops (Windows, Linux or OS/X) and log into a remote server running an OpenCL platform on a range of different processors. Alternatively, students can load OpenCL onto their own laptops prior to the course (Intel, AMD and NVIDIA provide OpenCL SDKs. Apple laptops with X-code include OpenCL by default). By the end of the course, attendees will be able to write and optimize OpenCL programs, and will have a collection of example codes to help with future OpenCL program development.

The current high-performance computing revolution provides opportunity for major increases in computational power over the next several years, if it can be harnessed. This transition from simply increasing the single-processor and network performance to a different architectural paradigms forces application programmers to rethink the basic models of parallel programming from both the language and problem division standpoints. One of the major computing facilities available to researchers in fusion energy is the National Energy Research Scientific Computing Center. As the mission computing center for DOE, Office of Science, NERSC is tasked with helping users to overcome the challenges of this revolution both through the use of new parallel constructs and languages and also by enabling a broader user community to take advantage of multi-core performance. We discuss the programming model challenges facing researchers in fusion and plasma physics in for a variety of simulations ranging from particle-in-cell to fluid-gyrokinetic and MHD models.

Modelling and mitigation of damage are crucial for safe and economical operation of high-power laser facilities. Experiments at the National Ignition Facility use a variety of targets with a range of laser energies spanning more than two orders of magnitude (~14 kJ to ~1.9 MJ). Low-energy inertial confinement fusion experiments are used to study early-time x-ray load symmetry on the capsule, shock timing, and other physics issues. For these experiments, a significant portion of the target is not completely vaporized and late-time (hundreds of ns) simulations are required to study the generation of debris and shrapnel from these targets. Damage to optics and diagnostics from shrapnel is a major concern for low-energy experiments. We provide the first full-target simulations of entire cryogenic targets, including the Al thermal mechanical package and Si cooling rings. We use a 3D multi-physics multi-material hydrodynamics code, ALE-AMR, for these late-time simulations. The mass, velocity, and spatial distribution of shrapnel are calculated for three experiments with laser energies ranging from 14 to 250 kJ. We calculate damage risk to optics and diagnostics for these three experiments. For the lowest energy re-emit experiment, we provide a detailed analysis of the effects of shrapnel impacts on optics and diagnostics and compare with observations of damage sites.

Cherri M. Pancake, Debra Goldfarb, Alice Koniges, Candy Culhane, The View, HPC Edition, SC11 Panel, November 2011,

This panel will be a take-off on ABC's popular morning talk program. A lively format will be used to cover a number of controversial topics in the development and application of HPC. Four women from the HPC world will serve as "co-hosts," discussing topics with international experts associated with specific topics, such as Jean-Yves Berthou (European Exascale Software Initiative), Dave Turek (IBM), Ryan Waite (Microsoft), and Matt Fetes (venture capitalist). The goal is to air a variety of viewpoints in a lively and entertaining way. The panel will raise thought-provoking questions such as why the HPC community has such a hard time converging on standards, whether co-design is really affordable at HPC scales, why efficiency isn't our goal rather than scalability, whether exascale investments can really pay off, and why high-level languages haven't had real impact in HPC. Interactive polling will be used to involve the audience in charting a course for HPC's future - so be sure to bring your laptop or smartphone.
