Native offload of Haskell repa programs to integrated GPUs

Hai Liu, Laurence E. Day, Neal Glew, Todd A. Anderson, Rajkishore Barik
2014 Proceedings of the 3rd ACM SIGPLAN workshop on Functional high-performance computing - FHPC '14  
benchmarks, comparing to two different CPUs, and for one benchmark to handwritten OpenCL code. • Repa programs are statically type-checked and compiled, whilst those written using Accelerate are only  ...  compiled at runtime. • The DSL compiler for Accelerate has to re-implement optimizations already implemented by the host-language compiler.  ...  Accelerate [4] and Obsidian [22] are two examples of this approach, using the functional language Haskell.  ...

Efficient query processing in co-processor-accelerated databases [article]

Sebastian Breß, Universitäts- Und Landesbibliothek Sachsen-Anhalt, Martin-Luther Universität, Gunter Saake
2018
This thesis shows how we can build database management systems that efficiently use heterogeneous processors to reliably accelerate database query processing.  ...  Our investigations show that co-processors can significantly slow down a DBMS when not used appropriately and develop approaches that avoid using co-processors when we expect a performance degradation.  ...  To speed up GiST lookup operations with coprocessors such as GPUs, Beier and others implemented a framework that abstracts from the hardware where index scans are actually executed and therefore, hide  ...

Development of an embedded device for real-time detection of atrial fibrillation and atrial flutter in single-channel ECG, using optimised classification based on a large training corpus

Eric Auer, Oliver Scholz, Daniel Strauss
2021 Zenodo  
The algorithm uses morphological analysis of the averaged ECG shape, properties of the R/R interval distribution and spectral analysis of the ECG to create a feature vector used for classification.  ...  Building on an earlier proof of concept project work by the author, this thesis presents a fully integrated, custom device, using an advanced classification algorithm trained on thousands of short, annotated  ...  Scan for maximum before S to find R. If R is positive, scan 120 ms for next minimum to find S.  ...

Acceleration of image recognition on Caffe framework using FPGAs [article]

Dimitrios Danopoulos, National Technological University Of Athens, National Technological University Of Athens
2018
Then the input image is scanned for features using small filters. This feature extraction starts with the input image where each pixel represents the input for the neurons grouped in features.  ...  They share a standard format for packaging in Caffe and are found in a central wiki page for sharing info Gists.  ...  The following tables list all the data movers and various properties for each used in each kernel.  ...

CS1 pedagogical approach to parallel thinking

Brian William Rague
2012
A new evaluation instrument developed for this study, the Perceptions of Parallelism Survey (PoPS), was used to measure student learning regarding parallel systems.  ...  Logical thinking is highlighted, guided primarily by a sequential approach to algorithm development and made manifest by typically using the latest, commercially successful programming language.  ...  Efficient network interface, pro- tection, events, active messages, and coprocessors in large-scale designs.  ...
