Abstract:
The rapid growth of datasets in applications significantly changes the landscape of modern computer architectures as they incorporate hardware accelerators, GPGPUs, non-volatile storage devices, in addition to traditional architectural components. However, these computers as well as programs running on top of them still inherit the half-century-old, layered system design that relies on the relatively slowly evolved CPU technologies. As a result, the overhead of layering has become an emerging bottleneck in performance.
To allow computers to make efficient use of modern heterogeneous computing units and data storage devices, and lead to performance improvements, we should revisit the entrenched layered system. Instead of local optimizations, we should take a holistic view of our system components when designing applications. To facilitate holistic system design but still maintain the benefits of layered design, we need to revisit the interface that each component exposes, remove redundant layers, and rethinking the roles of system components.
