IRIX IRIX Scalability Gabriel Broner This paper describes SGI's approach to scalability using both single systems and clusters. As a result of scalability and reliability enhancements to the IRIX Operating System we are now beta testing 256-processor Origin systems. Further, clustering enhancements have made clustering a practical alternative for scalability. IRIX Resource Management Plans and Status Dan Higgins This paper will detail what work has been done and the schedule for completing, testing and delivering the remaining work in the areas of IRIX Job Limits, IRIX Comprehensive System Accounting, IRIX Scheduling and Workload Management. Experiences with the SGI/Cray Origin 2000 256 Processor System Installed at the NAS Facility of the NASA Ames Research Center Jens Petersohn and Karl Schilke The NAS division of the NASA Ames Research Center installed a 256 processor single system image Origin 2000 system, the first at a customer site, during the later half of October 1998. Due to the large number of processors, the system exhibits different operational characteristics than smaller Origin 2000 systems. The causes of the observed behavior are discussed along with progress towards solving or reducing the effect of problem areas. Table of Contents | Author Index | CUG Home Page | Home (Title Page)
