    Abstract

    On 23 November 1992, the Department of Science and Technology (DST) convened a meeting; to discuss 'Future Supercomputing Strategies for Medium Range Weather Forecasting'. Subsequently it was decided to invite developers of indigenous parallel processing systems (PPS) to evolve suitable strategies of implementation of weather forecasting codes on their respective parallel machines. The aim of this project, as correctly stated by Bass in a recent report in this journal', was to demonstrate amongst the scientific community whether the PPS developed in India are capable of handling large applications with reasonable case and also to benchmark the different PPS machines by running the same application code (namely the spectral model at T80 resolution) with identical initial and boundary conditions provided by a common agency (the NCMRWF). DST realized that India might have a head start in the field of parallel computing. and its attempt to enhance and augment the indigenous technological base in this (then) emerging Field for a well defined national task was indeed commendable.13; Basu was the co-ordinator of this exercise and his paper summarizes his findings and views. In the present note, we present certain aspects, which appear to have been overlooked by the author and therefore makes his assessment13; misleading, and offer a different per spective on the project and its international counterparts hosed on personal experience of one of us (RSN) in India and the US.13;
