Abstract

Today, most computing platforms for HPC have heterogeneous hardware resources (CPUs, GPUs, storage, etc.) The most powerful supercomputers today have millions of those resources. In order to use all the computational power available, applications must be composed of multiple tasks that must use all available resources as efficiently as possible.The Job Management System (JMS) is the middleware responsible for distributing computing power to applications. A JMS must allocate resources to tasks in order to optimize the use of the available resources while guaranteeing good performance for all applications running on parallel. A promising way to achieve this is using performance prediction. However, in a scenario with millions of processors and large number of tasks it is very difficult to predict the performance of applications.This research project proposes the study of machine learning algorithms to support scheduling of tasks on large number of computational resources. We will apply learning techniques to devise novel scheduling algorithms that are capable of performing performance prediction from actual execution traces and developer's (uncertain) estimations.Using our previous results on GPU performance characterization and data collected from several JMSs, we will analyze the applicability of machine learning algorithms to predict running time of heterogeneous applications.
