Programming Perspectives for Pre-exascale Systems

Reservoir simulation of large scale projects is becoming increasingly complex, requiring more than simple black oil models and vertical well models to capture the behaviour of unconventional, fractured and highly heterogeneous production zones. Nvidia provides an array of accelerated linear algebra libraries to deal with the equations that must be solved in these situations. Accelerating sparse linear algebra on the latest GPU architectures has real potential for performance gains of hundreds of percent over carefully tuned multi-core CPU-only implementations, but at what cost in complexity? This talk will address the programming approaches needed to utilize GPUs at scale for today’s most challenging problems, and give a glimpse of the path forward to pre-exascale applications.
