Abstract


In applications HPC operations of I / O bottlenecks are due to the difference between processing speed and a given access. Thus, characterizing the operations can assist in the search for performance. Thus, this work proposes an unsupervised learning approach to characterize I / O. Using data Intrepid Supercomputer, we were able to identify the main feature of its applications.
