I/O Strategies for the T3E

I/O Strategies for the T3E. Jonathan Carter NERSC User Services. T3E Overview. T3E is a set of Processing Elements (PE) connected by a fast 3D torus. PEs do not have local disk All PEs access all filesystems equivalently Path for I/O generally looks like: user buffer space
