A Performance Comparison Using HPC Benchmarks: Windows HPC Server 2008 and Red Hat Enterprise Linux 5

This document was developed with support from the National Science Foundation (NSF) under Grant No. 0910812 to Indiana University for ”FutureGrid: An Experimental, High-Performance Grid Test-bed.” Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the NSF.A collection of performance benchmarks have been run on an IBM System X iDataPlex cluster using two different operating systems. Windows HPC Server 2008 (WinHPC) and Red Hat Enterprise Linux v5.4 (RHEL5) are compared using SPEC MPI2007 v1.1, the High Performance Computing Challenge (HPCC) and National Science Foundation (NSF) acceptance test benchmark suites. Overall, we find the performance of WinHPC and RHEL5 to be equivalent but significant performance differences exist when analyzing specific applications. We focus on presenting the results from the application benchmarks and include the results of the HPCC microbenchmark for completeness

Disseminated Histoplasmosis: A Challenging Differential Diagnostic Consideration for Suspected Malignant Lesions in the Digestive Tract

Histoplasmosis is well characterized as an endemic fungal disease restricted to certain areas of the USA. In Middle Europe, most patients present with acute pulmonary symptoms after travelling to endemic areas. Here, we want to illustrate the case of a 67-year-old man who presented with persistent oral ulcers, hoarseness, dysphagia, diarrhea, and weight loss to our Department of Otorhinolaryngology in December 2014. He was a retired construction worker and had a history of soil-disruptive activities in Africa and Middle and South America during employment. A positron emission tomography-computed tomography scan revealed prominent hypermetabolic lesions in the cecum and the lung, pointing towards a malignant disease. Surprisingly, histological examination of colonic and oral biopsies revealed abundant intracellular fungal elements, highly suspicious of Histoplasma capsulatum. Diagnosis was finally confirmed by panfungal polymerase chain reaction. Upon treatment with liposomal amphotericin followed by itraconazole, the severely ill patient showed an impressive clinical response. This case describes a disseminated manifestation of H. capsulatum years after the first exposure in an otherwise immunocompetent patient descending from a nonendemic area

New system for fast submicron optical direct writing

We report on a new system for submicron lithography by fast laser direct writing, where a programmable phase modulating spatial light modulator (SLM) is imaged onto the wafer using flash on the fly exposure with an excimer laser light source.A SLM with 512x464 pixels has been developed and fabricated using a CMOS active matrix and a reflective, deformable viscoelastic layer on top. Using this light modulator for image generation a demonstrator exposure tool for 0.6 mu m minimum feature size has been set up and tested including all the components necessary for the exposure of a complete lithographic layer from CAD layout data. the demonstrator is shown to give good quality 0.6 mu m photoresist pattern at a throughput of roughly one 4-inch-wafer per hour. Based on the demonstrator results we are designing and setting up a prototype of a production tool with an increased throughput of up to nine 6-inch-wafer per hour including an automatic alignment system and an automatic wafer handler
