Query: Transparent Compiler and Runtime Specializations for Accelerating
  Managed Languages on FPGAs   In recent years, heterogeneous computing has emerged as the vital way to
increase computers? performance and energy efficiency by combining diverse
hardware devices, such as Graphics Processing Units (GPUs) and Field
Programmable Gate Arrays (FPGAs). The rationale behind this trend is that
different parts of an application can be offloaded from the main CPU to diverse
devices, which can efficiently execute these parts as co-processors. FPGAs are
a subset of the most widely used co-processors, typically used for accelerating
specific workloads due to their flexible hardware and energy-efficient
characteristics. These characteristics have made them prevalent in a broad
spectrum of computing systems ranging from low-power embedded systems to
high-end data centers and cloud infrastructures.
  However, these hardware characteristics come at the cost of programmability.
Developers who create their applications using high-level programming languages
(e.g., Java, Python, etc.) are required to familiarize with a hardware
description language (e.g., VHDL, Verilog) or recently heterogeneous
programming models (e.g., OpenCL, HLS) in order to exploit the co-processors?
capacity and tune the performance of their applications. Currently, the
above-mentioned heterogeneous programming models support exclusively the
compilation from compiled languages, such as C and C++. Thus, the transparent
integration of heterogeneous co-processors to the software ecosystem of managed
programming languages (e.g. Java, Python) is not seamless.
  In this paper we rethink the engineering trade-offs that we encountered, in
terms of transparency and compilation overheads, while integrating FPGAs into
high-level managed programming languages. We present a novel approach that
enables runtime code specialization techniques for seamless and
high-performance execution of Java programs on FPGAs. The proposed solution is
prototyped in the context of the Java programming language and TornadoVM; an
open-source programming framework for Java execution on heterogeneous hardware.
Finally, we evaluate the proposed solution for FPGA execution against both
sequential and multi-threaded Java implementations showcasing up to 224x and
19.8x performance speedups, respectively, and up to 13.82x compared to
TornadoVM running on an Intel integrated GPU. We also provide a break-down
analysis of the proposed compiler optimizations for FPGA execution, as a means
to project their impact on the applications? characteristics.
