On December 6, Julien Monniot will defend his thesis entitled “Enabling accurate simulation of HPC storage systems: methodology and practical techniques“. Julien wrote his thesis under the supervision of Gabriel Antoniu and François Tessier. Here is a summary of his work:
The field of High Performance Computing (HPC), aims to provide scientists with systems able to sustain the requirements of complex scientific applications. These systems, supercomputers, have been in constant evolution in order to overcome new challenges and requirements. However, while the computing power of such platforms is generally the leading metric to define them, entire infrastructures must scale along in order to achieve the targetted performances. In particular, the recent years have seen a drastic increase in the volume of data handled by HPC, and in turn, large scale storage systems requirements and limitations are becoming of particular interest. Obtaining sufficient knowledge on how the applications are using these resources and how to accommodate a variety of use-cases is fundamental to progress towards even better performances. In this work, we present one method for acquiring such knowledge: enabling better simulation of complex storage systems, in order to facilitate broad and fast exploration of a wide array of management policies, design choices or bottleneck mitigations.
You are all very welcome to attend his defense!
