Steve Neuner, the director for Linux engineering at SGI, has been pushing Linux up the scalability ladder for the better part of the 21st century. In August of this year, SGI announced that they were able to run a single system image of the Linux OS over 1024 processors on an Itanium-based Altix 4700 supercomputer. How was this feat accomplished? This week at the Gelato Itanium Conference and Expo (ICE) in Singapore, Neuner presented a session that described the Linux kernel modification that helped to make this possible. HPCwire caught up with him before the conference to ask him about the Linux improvements and where the future of single system image scalability is headed.
