The PRACE Scientific and Industrial Conference 2015 (PRACEdays15) has issued its Call for Posters. PRACEdays15 will be held in Dublin, Ireland with a mission to “Enable Science and Foster Industry.
“The end of Dennard scaling has made all computing power limited, so that performance is determined by energy efficiency. With improvements in process technology offering little increase in efficiency innovations in architecture and circuits are required to maintain the expected performance scaling. The large scale parallelism and deep storage hierarchy of future machines poses programming challenges. Future programming systems must allow the programmer to express their code in a high-level, target-independent manner and optimize the target-dependent decisions of mapping available parallelism in time and space. This talk will discuss these challenges in more detail and introduce some of the technologies being developed to address them.”
“In working to improve future hardware and software for its simulation requirements, Sandia National Laboratories are engaging in co-design efforts with major hardware vendors. In this talk recent improvements influenced by the collaboration with NVIDIA will be discussed. The presentation will in particular focus on newly available experimental C++11 support in CUDA and how this facilitates both more rapid porting of applications to GPUs as well as better exploitation of GPU architecture characteristics. Furthermore, initial performance studies on NVIDIA’s next generation Tesla product line will be presented as well as first impressions of an IBM POWER-8 based GPU cluster.”
In the video interview shown below, Sithole describes how CHPC is on the fast track to acquire over a Petaflop of computing power in the next year to meet the demands of its regional scientists and engineers. That represents a daunting task for system management, and CHPC is already using PBS Professional software from Altair to keep their systems systems fully utilized.
“By working with ThinkParQ, we have been able to leverage one of the best and highest performance storage systems for scale-out deployment,” said Dr. Joseph Landman, CEO of Scalable Informatics. “When testing a write-dominated workload using fio, IOR, and io-bm,a single rack of FastPath Unison with BeeGFS running on spinning disks sustained in excess of 40GB/s for multi-terabyte sized writes,far outside of cache. This level of performance comes from the combination of FastPath Unison hardware design, the Scalable Informatics Operating System (SIOS), and the excellent BeeGFS filesystem.”
