The Pennsylvania State University The Graduate School College of Communications EVALUATIO OF FOSS VIDEO GAMES I COMPARISO TO THEIR COMMERCIAL COUTERPARTS A Thesis in Media Studies By Jesse A. Clark © 2008 Jesse A. Clark Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Arts August 2008 ii The thesis of Jesse A. Clark was reviewed and approved* by the following:: John Nichols Professor of Communications Associate Dean for Graduate Studies and Research Matt Jackson Associate Professor of Communications Head of Department of Telecommunications Thesis Advisor Robert Frieden Professor; Pioneers Chair in Telecommunications Ronald Bettig Associate Professor of Communications *Signatures are on file in the Graduate School. iii Abstract The topic of copyrights and copyright law is a crucial component in understanding today's media landscape. The purpose for having a copyright system as outlined in the U.S. Constitution is to provide content creators with an incentive to create. The copyright system allows revenue to be generated through sales of copies of works; thus allowing for works to be created which otherwise would not be created. Yet it is entirely possible that not all large creative projects require the same legal framework as an incentive. The so called “copyleft” movement (which will be defined and explained in depth later) offers an alternative to the industrial mode of cultural production. Superficially, “copylefted” works can be divided into two broad categories: artistic/creative works (which are often protected by “Creative Commons” licenses), and Free/Open Source Software. This thesis evaluates how open source video games compare to their commercial counterparts and discusses the reasons for any difference in overall quality. -

However, the choice of relevant benchmarks still remains a challenge. To help the process of comparing and choosing among benchmarks, we propose a solution for automatic benchmark profiling. It computes unified benchmark profiles reflecting benchmarks’ duration, function repartition, stability, CPU efficiency, parallelization and memory usage. -

Součástí práce bylo vytvoření sady testù pro měření výpočetního výkonu procesoru, propustnosti operační paměti, rychlosti zápisu a čtení z per- sistentního úložiště (paměťové karty) a propustnosti síťového rozhraní Ethernet. Na základě porovnání výsledků získaných měřením na Raspberry Pi a na vhod- ném reprezentativním vzorku dalších běžně dostupných počítačů bylo provedeno doporučení, zda je konstrukce Raspberry Pi klastru opodstatněná. Tyto výsledky rovněž poskytly přibližné ekonomické a výkonnostní projekce takového řešení.

Xeon Platinum 8280 Vs. AMD EPYC 7742 - Ubuntu Linux
www.phoronix-test-suite.com Xeon Platinum 8280 vs. AMD EPYC 7742 - Ubuntu Linux AMD EPYC and Intel Xeon benchmarks by Michael Larabel... Mix of single and multi-threaded workloads. Admittedly somewhat random tests with the intent of just being to doing some validation on Phoronix Test Suite 9.4 and checking out the graphing code, PDF generation, etc. Take the actual results as you wish. Automated Executive Summary 2 x EPYC 7742 had the most wins, coming in first place for 61% of the tests. Based on the geometric mean of all complete results, the fastest (2 x EPYC 7742) was 1.2x the speed of the slowest (2 x Xeon Platinum 8280). The results with the greatest spread from best to worst included: Tungsten Renderer (Scene: Volumetric Caustic) at 3.53x - MBW (Test: Memory Copy - Array Size: 4096 MiB) at 3.22x - Parboil (Test: OpenMP MRI Gridding) at 3.02x - Hackbench (Count: 32 - Type: Process) at 3.01x - Tachyon (Total Time) at 2.62x - C-Ray (Total Time - 4K, 16 Rays Per Pixel) at 2.37x - dav1d (Video Input: Chimera 1080p) at 2.33x Xeon Platinum 8280 vs. AMD EPYC 7742 - Ubuntu Linux - Coremark (CoreMark Size 666 - Iterations Per Second) at 2.3x - dav1d (Video Input: Summer Nature 1080p) at 2.17x - GraphicsMagick (Operation: Sharpen) at 2.17x.
