11. MACHINE REQUIREMENTS
IBM 7090 - a 32k store is required for the standard version of the programme arranged to take up to 32 x 32 mesh points. Simple changes to a number of dimension statements would allow the programme to be accommodated in a smaller store.
A clock is required by the standard version, though this could be dispensed with by simple modifications to the programme. Where a clock is not available, a modificed version of the programme terminates on total burnup time rather than total execution time.
IBM 7030 - the 7030 version is written in S2 suitable for use on the Aldermaston computer. Variable dimension statements are employed so that the programme could be used in different sizes of core, e.g. when a 80,000 store is available up to 61 x 61 mesh points can be employed.
