Application: Australian Square Kilometer Array Pathfinder*
(ASKAP) tHogBomClean.
Description: The tHogBomClean benchmark implements the
kernel of the HogBom Clean deconvolution algorithm. This
benchmark is quite minimal and actually omits the final step,
convolution of the model with the clean beam, but this
involves the similar operations to the other steps as far as
the CPU is concerned. More here.
Availability:
• Code: Available here.
• Recipe: Not available. Check for future availability at here.
Usage Model: Native execution on Intel® Xeon® processor
E5-2697 v3 , Intel® Xeon Phi coprocessor 7120, and NVIDIA
K40*, using the same codebase.
Results:
• The Intel Xeon processor E5-2697 v3 increased
performance up to 1.39X compared to NVIDIA K40*.
• The Intel Xeon Phi coprocessor 7120 increased
performance up to 1.57X compared to NVIDIA K40.
• The Intel Xeon Phi coprocessor 7120 increased
performance up to 1.12X compared.to Intel Xeon
processor E5-2697 v3.
Software and workloads used in performance tests may have been optimized for performance only on Intel microprocessors. Performance tests, such as SYSmark and MobileMark, are measured using specific computer systems,
