<p dir="ltr" style="text-align:justify"><span style="color:#000000; font-family:Arial; font-size:11pt">The Workshop On Performance and Scalability of Storage Systems (WOPSSS) aims to present state-of-the-art research, innovative ideas, and experience that focus
on the design and implementation of HPC storage systems in both academic and industrial worlds, with a special interest on their performance analysis.</span></p>
<p style="text-align:justify" dir="ltr"><span style="color:#000000; font-family:Arial; font-size:11pt">This year, for our 5th edition, we propose to give a specific twist to address the system and operating system aspects of the storage stack. The addressed
workloads remain HPC, Big Data, Cloud, and Artificial Intelligence. All these data intensive domains have to overcome the I/O bottleneck by analyzing the performance, detecting parameters restricting the performance and eventually providing I/O optimizations.</span></p>
<p dir="ltr" style="text-align:justify"><span style="color:#000000; font-family:Arial; font-size:11pt">WOPSSS intends to encourage the discussion of these topics between researchers and practitioners from both the academic and the industrial worlds.</span></p>
<p dir="ltr"><span style="color:#000000; font-family:Arial; font-size:11pt">The workshop is held in conjunction with EuroSys'20.</span></p>
<h2>Submission Guidelines</h2>
