 +  * 10:05 **Toward Next Generation Interfaces for Exploiting Workflows** -- Julian Kunkel \\ //The efficient, convenient, and robust execution of data-driven workflows is key for productivity in scientific computing. However, managing IO workflows efficiently in data centers is challenging for users. In order to achieve the best IO performance,​ a user must consider the characteristics of the various available storage systems and file systems and map the IO of their workflows manually to the storage systems. This talk introduces a wider datacenter vision on the handling of workflows and then our general vision the abstraction bears to the typical IO stack in the domain of climate and weather. Within ESiWACE, we move toward this vision by integrating capabilities into the software stack that increases the abstraction level of IO within workflows and enables the software stack to optimize data placement and handle the information lifecycle automatically. We then show our design for the ESiWACE prototype that utilizes software components such as Cylc, SLURM, ESDM, and XIOS. Next, we discuss how such an approach could be integrated into existing workflows. Finally, the Next-Generation Interfaces effort is introduced.//​ \\ {{ :​events:​2020:​sig-io-uk-kunkel-workflows.pdf |Slides}} 
 +  * 10:30 **Persistent memory for I/O** -- Adrian Jackson \\ //This talk presents the work done during the EU funded NEXTGenIO project, looking at enabling exascale I/O for computational simulation, data analytics, and machine learning. We focus on non-volatile,​ in-node, memory, how it can be used, and the performance benefits and usage pitfalls that it provides.// \\ {{ :​events:​2020:​sig-io-uk-nextgenio.pdf |Slides}} 
 +  * 11:00 **Sage2: Addressing Exascale Storage Challenges** -- Sai Narasimhamurthy \\ {{ :​events:​2020:​sig-io-uk-sage2_-addressing_exascale_storage_challanges.pdf |Slides}} 
 +  * 11:30 **Interoperability as the new frontier** -- Jean-Thomas Acquaviva \\ //As illustrated by IO500 benchmark in recent years HPC storage systems have considerably push the boundaries of performance. Not only from a quantitative standpoint with unprecedented throughput or capacity numbers but also in qualitative terms with the ability to deal with a much larger spectrum of workloads. Such progress, driven by new workloads such as AI are only of part of the answer. Nowadays performance equation has to integrated the complexity of the environment,​ storage systems are not used only as output for huge numerical simulations but integrated within the complex work and data flows. Therefore, the new frontier is about interoperability and the ability for a storage solution to be seamlessly integrated with other data hubs such as clouds either private or public. Our talk will discuss the evolution of the raw performances and will open-up on the on-going efforts for a better integration within modern data flows. This is the ransom of success and the way HPC technologies will carve their way to mainstream environments.// ​ \\ {{ :​events:​2020:​sig-io-uk-ddn.pdf |Slides}}

NVMe and other high-performance storage devices offer extreme performance at increasingly affordable prices. With these technology shifts, what software we use for different tasks and what we can afford to do is changing. This talk will explore how things are changing and where new opportunities to enable science exist.// ​ \\ {{ :​events:​2020:​sig-io-uk-memory_vs._storage.pdf |Slides}}
