Prof. Hamada will describe issus, show photographs of several stages of his cluster, and discuss pricing, sourcing, timing, and labor requirements.<\/p>\n<h4>Software<\/h4>\n<p>There are two aspects to be considered in terms of software requirements: \u00a0the system configuration (operating system, file system, setting accounts) and the cluster management tools. \u00a0Prof. Hamada will spend time explaining his tested solutions for these two aspects, and also demonstrate his own tools for parallel management. \u00a0He will not only demonstrate, but make available his programs providing parallel shell scripts for broadcasting instructions to all nodes. \u00a0He will also share his testing suite, to be used for detecting faulty gaming cards, and discuss strategies for fault-tolerant computing.<\/p>\n<p>Participants in this course will have access to the wealth of knowledge obtained from building several generations of GPU clusters. \u00a0Starting in March 2007 with a 1 Tflop\/s system, and ending with the award-winning GPU cluster Degima with 576 GPUs.<\/p>\n<h3>Printable course description<\/h3>\n<p style=\"padding-left: 30px;\"><a href=\"\/pasi\/files\/2010\/08\/PASI-Hamada-course1.pdf\">PASI Hamada course<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>by Professor Tsuyoshi Hamada Nagasaki Advanced Computing Center This course is based on the experience at the Nagasaki Advanced Computing Center building a GPU cluster to win the Gordon Bell prize in the price\/performance category. \u00a0After several years trying, finally the coveted prize was awarded to Professor Hamada and his co-authors in 2009.
