Workshop description

With the Exascale gradually becoming a reality for the supercomputing community, memory and I/O bottlenecks remain two of the key challenges that need to be solved in order for applications to be able to fully exploit the capabilities of these systems. The NEXTGenIO project partners have been collaborating closely over the past four years to design, build and deliver a prototype hardware platform based around new non-volatile memory (NVRAM) technology. In addition to the hardware, the project has also developed a full software stack which is deployed on the prototype and which explores its novel capabilities.

This workshop will discuss the usage scenarios for byte-addressable persistent memory and the impact it will have on high-performance computing and data intensive applications. Speakers at the workshop will represent the user community, hardware vendors and software tools providers.

Abstract submission

We are seeking submissions in the following formats:

Oral presentation

Poster presentation

Contributions to the workshop presentations and posters should focus on the Exascale I/O and Memory challenges and experience with Storage Class Memory and byte-addressable Non-Volatile storage, from the level of single applications to full integrated workflows.

We welcome contributions from research institutions, software developers, HPC centres, hardware providers and industrial applications.
