HPC applications with suboptimal I/O behavior interfere with well-behaving applications and lead to increased application runtime. In some cases, this may even lead to unresponsive systems and unfinished jobs. HPC monitoring systems can aid users and

Every day, supercomputers execute 1000s of jobs with different characteristics. Data centers monitor the behavior of jobs to support the users and improve the infrastructure, for instance, by optimizing jobs or by determining guidelines for the next

The perceived I/O performance of a shared file system heavily depends on the usage pattern expressed by all concurrent jobs. From the perspective of a single user or job, the achieved I/O throughput can vary significantly due to activities conducted

It is not uncommon to run tens of thousands of parallel jobs on large HPC systems. The amount of data collected by monitoring systems on such systems is immense. Checking each job individually by hand, e.g., for identification of high workloads or de

Parallel application I/O performance often does not meet user expectations. Additionally, slight access pattern modifications may lead to significant changes in performance due to complex interactions between hardware and software. These challenges c

Many scientific applications are limited by I/O performance offered by parallel file systems on conventional storage systems. Flash-based burst buffers provide significant better performance than HDD backed storage, but at the expense of capacity. Bu

In current supercomputers, storage is typically provided by parallel distributed file systems for hot data and tape archives for cold data. These file systems are often compatible with local file systems due to their use of the POSIX interface and se

The starting point for our work was a demand for an overview of application’s I/O behavior, that provides information about the usage of our HPC “Mistral”. We suspect that some applications are running using inefficient I/O patterns, and probab
