Access "Object-based File Systems come of age for HPC"

Anil Patrick R, Chief Editor, TechTarget, India Published: 12 Oct 2012

With the 10 petaflop barrier breached in late 2011, the global high-performance computing (HPC) community’s dream of crossing into exascale (1,000 petaflops) territory by 2018 suddenly looks all the more realistic. Whether India will beat Japan, China, United States and others to this achievement is a matter of academic debate, but all face challenges that center on constraints in existing HPC architectures, including limitations in today’s file systems. The file system is a critical component because it affects aspects such as read-write capabilities required by supercomputing setups. This is where object-based file systems can provide advantages over traditional methods such as distributed file systems and parallel file systems used in HPC. Today, HPC architects have a choice of two different approaches to object-based file systems: one is open source and software-based (Lustre) and the other a bundled software/hardware system (Panasas). Both offer more I/O pos­sibilities than traditional parallel file system technology.     Evolutionary road Early HPC ... Access >>>
