The concept of buying an organization's computing needs on a pay-as-you-go basis is known as Utility Computing. In this model, organizations pay for the usage of applications, either to Information Technology (IT) departments or to an external technology vendor. This approach is similar to the way consumers pay for utility services like electricity, gas,(More)
Finding the spectrum of a signal swiftly has been an ever-growing demand in Digital Signal Processing. In quest to meet this stipulation, Discrete Hartley Transform (DHT) is becoming as an encouraging substitute to the more popular discrete Fourier transform. Fast methods to compute the DHT are in existence and are named as fast Hartley transforms (FHTs).(More)
In this paper 1 we discuss the parallel implementation of multidimensional FFTs on distributed memory multi-processor machines. We introduce a compact notation to describe four equivalent parallel algorithms and discuss their advantages and disadvantages. Two algorithms, suitable for the case when initial and nal data are distributed either row-or(More)
