TSUBAME2: How to Manage a Large GPU-Based Heterogeneous Supercomputer

Satoshi Matsuoka gave this talk at the PBS Works User Group this week. “The Tokyo Tech. TSUBAME2 supercomputer is one of the world’s leading supercomputer, ranked as high as #4 in the world on the Top500 and recognized as the “greenest supercomputer in the world” on the Green 500. With the GPU upgrade in 2013, it still sustains high performance (5.7 Petaflops Peak) and high usage (nearly 2000 registered users). However, such performance levels have been achieved with pioneering adoption of latest technologies such as GPUs and SSDs that necessitated non-traditional strategies in resource scheduling.”
