The development of photonic technologies to speed up computing has taken two steps forward, following recent announcements demonstrating the use of photonics in both processing and data transfer.

PNNL Looks at Undervolting to Meet Exascale Goals

Figure depicting the general constraints at scale for building exascale architectures. The undervolting component (shown in 4) is part of ongoing work that PNNL’s HPC group and their collaborators are conducting in the effort to build highly resilient and energy-efficient HPC systems.

PNNL researchers are using supercomputers to take on two of the main challenges of exascale: energy efficiency and resiliency. Their simulations show that dynamic voltage scaling, also known as undervolting, can reduce power consumption and leverage existing mainstream resilience techniques at scale for improving system failure rates.

Lustre & Kerberos: In Theory and In Practice

“Kerberos is the most famous way to allow safe communications over a non-secure network, by providing authentication and encryption. This presentation will show how far Lustre can go in Kerberos security, and what kind of authentication and encryption we can get to work. We will also take an interest in the impact of various Kerberos flavors over performance.”

Hunting Supernovas with Supercomputers

“This talk will discuss various strategies to make a serial Python code faster, for example using libraries like NumPy, or tools like Cython which compile Python code. The talk will also discuss the available tools for running Python in parallel, focusing on the mpi4py module which implements MPI (Message Passing Interface) in Python.”
