By Jatin Chhugani,Nadathur Satish,Changkyu Kim,Jason Sewall,Pradeep Dubey
Issue Date:May 2012
Graph-based structures are being increasingly used to model data and relations among data in a number of fields. Graph-based databases are becoming more popular as a means to better represent such data. Graph traversal is a key component in graph algorithm...
Designing efficient sorting algorithms for manycore GPUs
Parallel and Distributed Processing Symposium, International
By Nadathur Satish,Mark Harris,Michael Garland
Issue Date:May 2009
We describe the design of high-performance parallel radix sort and merge sort routines for manycore GPUs, taking advantage of the full programmability offered by CUDA. Our radix sort is the fastest GPU sort and our merge sort is the fastest comparison-base...
An automated exploration framework for FPGA-based soft multiprocessor systems
Hardware/software codesign and system synthesis, International conference on
By Kurt Keutzer, Kaushik Ravindran, Nadathur Satish, Yujia Jin
Issue Date:September 2005
FPGA-based soft multiprocessors are viable system solutions for high performance applications. They provide a software abstraction to enable quick implementations on the FPGA. The multiprocessor can be customized for a target application to achieve high pe...
3.5-D Blocking Optimization for Stencil Computations on Modern CPUs and GPUs
By Anthony Nguyen, Nadathur Satish, Jatin Chhugani, Changkyu Kim, Pradeep Dubey
Issue Date:November 2010
Stencil computation sweeps over a spatial grid over multiple time steps to perform nearest-neighbor computations. The bandwidth-to-compute requirement for a large class of stencil kernels is very high, and their performance is bound by the available memory...
Can traditional programming bridge the Ninja performance gap for parallel computing applications?
Found in: Proceedings of the 39th Annual International Symposium on Computer Architecture (ISCA '12)
By Changkyu Kim, Hideki Saito, Jatin Chhugani, Mikhail Smelyanskiy, Milind Girkar, Nadathur Satish, Pradeep Dubey, Rakesh Krishnaiyer
Issue Date:June 2012
Current processor trends of integrating more cores with wider SIMD units, along with a deeper and complex memory hierarchy, have made it increasingly more challenging to extract performance from applications. It is believed by some that traditional approac...
Designing fast architecture-sensitive tree search on modern multicore/many-core processors
