Persistent Asynchronous Adaptive Specialization for Generic Array Programming

Clemens Grelck, Heinrich Wiesinger
2018 International journal of parallel programming  
A number of critical issues that, among others, stem from the interplay between function specialization and function overloading catch our special attention.  ...  We describe the solutions adopted and illustrate the benefits of persistent asynchronous adaptive specialization by a series of experiments.  ...  Apart from the obvious reason that generic code maintains more information in runtime data structures, the crucial issue are the SaC compiler's advanced optimizations [3] that are not as effective on  ...

Analyzing Behavior Specialized Acceleration

Tony Nowatzki, Karthikeyan Sankaralingam
2016 ACM SIGOPS Operating Systems Review  
Of significant interest are Behavioral Specialized Accelerators (BSAs), which are designed to efficiently execute code with only certain properties, but remain largely configurable or programmable.  ...  Hardware specialization has become a promising paradigm for overcoming the inefficiencies of general purpose microprocessors.  ...  Conservation Cores are automatically generated, simple hardware implementations of application code [53] , which are meant as offload engines for in-order cores.  ...

Stream Semantic Registers: A Lightweight RISC-V ISA Extension Achieving Full Compute Utilization in Single-Issue Cores [article]

Fabian Schuiki, Florian Zaruba, Torsten Hoefler, Luca Benini
2020 arXiv   pre-print
Single-issue processor cores are very energy efficient but suffer from the von Neumann bottleneck, in that they must explicitly fetch and issue the loads/storse necessary to feed their ALU/FPU.  ...  Sequential code runs 3x faster on a single core, and 3x fewer cores are needed in a cluster to achieve the same performance.  ...  Existing software would be able to make use of our architectural extension via simple recompilation without the need for re-engineering work.  ...

Bridging the Gap Between General-Purpose and Domain-Specific Compilers with Synthesis

Alvin Cheung, Shoaib Kamil, Armando Solar-Lezama, Marc Herbstritt
2015 Summit on Advances in Programming Languages  
By leveraging general synthesis technology, it is possible to have a generic kernel translator that can be specialized by compiler developers for each domainspecific compiler, making it easy to build new  ...  Each kernel translator is associated with a domain-specific compiler, and the role of each kernel translator is to scan the input code in search of code fragments that can be optimized by the domain-specific  ...  Introduction Despite significant advances in compiler optimization over the last thirty years, the promise of actual optimality in generated code remains elusive; even today, clean and high-level code  ...
