ABSTRACT:
Drawing parallels to the rise of general purpose graphical processing units (GPGPUs) as accelerators for specific high-performance computing (HPC) workloads, the HPC community is also witness to a recent rise in the use of non-volatile memory (NVM), such as flash-based solid-state drives (SSDs), as accelerators for certain I/O-intensive workloads. These NVM acceleration architectures have been shown to work particularly well for read-intensive scientific applications such as out-of-core numerical linear algebra, where matrices too large for individual nodes' main memory tend to be calculated once and read many times. However, existing works have explored use of NVM within dedicated I/O nodes, which are distant from the compute nodes that actually need such acceleration. As NVM bandwidth begins to out-pace point-to-point network capacity, we argue for the need to break from the archetype of completely separated storage and consider compute-local solutions involving NVM.
