12 Feb 2018 | | Abstract: | In this work, we introduce a Self-Aware Polymorphic Architecture (SAPA)
design approach to support emerging context-aware applications and mitigate the
programming challenges caused by the ever-increasing complexity and
heterogeneity of high performance computing systems. Through the SAPA design,
we examined the salient software-hardware features of adaptive computing
systems that allow for (1) the dynamic allocation of computing resources
depending on program needs (e.g., the amount of parallelism in the program) and
(2) automatic approximation to meet program and system goals (e.g., execution
time budget, power constraints and computation resiliency) without the
programming complexity of current multicore and many-core systems. The proposed
adaptive computer architecture framework applies machine learning algorithms
and control theory techniques to the application execution based on information
collected about the system runtime performance trade-offs. It has heterogeneous
reconfigurable cores with fast hardware-level migration capability,
self-organizing memory structures and hierarchies, an adaptive
application-aware network-on-chip, and a built-in hardware layer for dynamic,
autonomous resource management. Our prototyped architecture performs extremely
well on a large pool of applications. | | Source: | arXiv, 1802.5100 | | Services: | Forum | Review | PDF | Favorites | |
