You can, as long as the square cover the world in what is known as the “Battle of the Brains” is big enough. It obviously will not on April 18–22, 2009 in Stockholm, Sweden. be an exact fit, but it is still possible to cover the hole completely. The Association of Cover Manufacturers (ACM) is a group of companies that produce covers for all kinds of holes — manholes, holes on streets, wells, ditches, cave entrances, holes in backyards dug by dogs to bury bones, to name only a few. ACM wants a program that determines whether a given cover can be used to completely cover a specified hole. At this time, they are interested only in covers and holes that are rectangular polygons (that is, polygons with interior angles of only 90 or 270 degrees). Moreover, both cover and hole are aligned along the same coordinate axes, and are not supposed to be rotated against each other — just translated relative to each other. Input The Illinois ACM-ICPC world qualifying team (from left to right): The input consists of several descriptions of covers and holes. The first line CS sophomore Pichayoot Ouppaphan, CS PhD students Yintao Yu and Mianwei Zhou. of each description contains two integers h and c (4 ? h ? 50 and 4 ? c ? 50), the number of points of the polygon describing the hole and the cover respectively.

We are in the process of replacing the requirement of a one semester senior laboratory taken in a narrow area of specialization (ceramics, electronic materials, metals, polymer, or biomaterials) with a Greetings requirement that each student enroll in four ½-semester “lab modules” of their choice. We will be doubling the hours of laboratory instruction from Urbana in the senior year from 3 to 6, essentially replacing one lecture course with three hours of laboratory instruction. The new lab modules are intended to be more dynamic than the relatively static topics that we offered in the past; topics covered in the lab modules will be responsive and reflect changes in the field.

  • Programming Models for Parallel Heterogeneous Computing
    Programming Models for Parallel Heterogeneous Computing Frank Feinbube [email protected] This paper describes my work with the Operating Systems and Middleware group for the HPI Research School on "Service-Oriented Systems Engineering". 1 Motivation Many of the computational problems we are facing today are complex and need huge computational power to be solved. It is well-known that processors will not continue to get faster, but will get more cores instead. More cores are not only harder to utilize by an application programmer, but also challenge hardware designers. Thus various new hardware architectures are designed and evaluated in order to find the ones that will fulfill the needs of future computer systems. Prototypic configuration boards like Intels Single Chip Cloud Computer (SCC) are an attempt to deal with the ever-increasing number of cores by removing essential features of current processors like hardware cache coherency. Another approach is to accompany common general purpose CPUs with sophisticated special purpose processing units. These so called Accelerators are easier to build and very fast for specific application purposes. They are the foundation for the new trend of hybrid computer systems. 2 Domains of Hybrid Systems 2.1 High Performance Computing The High Performance Computing (HPC) community has a steady need for an increase of floating point operations per second (FLOPS) in order to simulate natural processes with a higher accuracy. Therefore enormous computer clusters are used. These su- percomputers are not only very expensive to build, but do also need a huge amount of energy, both for processing and for cooling.

Director: Jassim, Emad. Entidad colaboradora: Universidad de Illinois, Johnsons Controls. RESUMEN DEL PROYECTO 1. Introducción El Centro Nacional de Aplicaciones para la Supercomputación (NCSA), está planeando mejorar y expandir el actual superordenador ‘Blue Waters’ en los próximos 15 meses, el superordenador está localizado en las instalaciones del Centro Nacional ‘Petascale’. Se necesita un sistema de refrigeración sofisticado y eficiente para poder eliminar la gran cantidad de calor generada por el superordenador. El nuevo sistema tendrá requisitos de potencia menores que el actual, esto junto a la capacidad que tendrá el sistema para aceptar temperaturas de entrada de agua mayores, nos dará la oportunidad de modificar el sistema actual de refrigeración con el objetivo de reducir los costes anuales, así como el uso de recursos naturales. El sistema actual de refrigeración tiene varios problemas. Primero, el sistema actual está sobredimensionado, está pensado para refrigerar el actual ordenador que disipa 11 MW de calor de pico y 6 MW de media, mientras que el nuevo disipa 3.8 MW de máxima. Además del superordenador se diseñará un sistema de refrigeración para el centro de almacenamiento de datos que tendrá distintas características térmicas.
