Analysis of Convolutional Resampling Algorithm Performance

  title={Analysis of Convolutional Resampling Algorithm Performance},
  author={Ben Humphreys and Tim Cornwell},
This memo provides an analysis of the convolutional resampling algorithm used in radio-astronomy imaging with respect to the imaging pipelines of the Australian Square Kilometre Array Pathfinder (ASKAP). Due to the large data rate (∼2.5GB/s), imaging an ASKAP scale data-set requires significant processing capability. In order to produce some capacity planning estimates and understand the efficiency of the imaging process, an analysis of one of the most computationally demanding algorithms… CONTINUE READING
