In the: figure three variables are assumed to be filtered. The left picture shows initial data row distribu tions in each node and how rows are redistributed The right picture shows load -balanced distribution of data rows. Figure 2 An example of data row transpose in east-wrest direction for parallel filtering with local FF The left picture shows data rou dlis tribution before transpose The right picture shows the data rou distri- bution after trans spose Implenenting Balaneed Faust Fourier Tramsform Joad Jeft 1531 1503
