CSIRAC Uses

In the eight years of operation (about 30,000 hours of 'uptime') at Melbourne University, over 700 computing projects were processed by CSIRAC. A brief list of these projects follows

• Simulations of the practical operation of the Victorian power supply system by the SECV (State Electricity Commission of Victoria).

• Pattern simulations for the arrangement of atoms in face centered cubic crystals (eg: tungsten and platinum).

• Evaluation of the growth rate of a stand of Pinus Radiata for the Forestry Commission of Victoria.

• Production of Solar Position and Radiation Tables for Australian capital cities for the CSIRO Division of Building Research.

• Calculation of the loan repayment schedule for University staff member's housing loans.

• Computation of the radiation patterns of the rhombic antennae used by the Army Signals Branch at Donnybrook.

• Rigid-frame and grid-frame analysis for many of the 'high'-rise buildings (to around 25 stories) built in Australia in the early 1960s.

Earlier, whilst still located in Sydney, the CSIR Mk1 had been used for

• Analysis of flood data for the design of dams for assembling the Snowy Mountains Hydroelectric Authority (SMHA).

As you can see, the programming projects were many and varied. A large number of the major engineering projects in Australia during the 50's and 60's had a major input from CSIRAC.

Not bad for a machine that was originally intended "as a research computer, in order that investigation into programming techniques and electronic computer circuitry could be undertaken".
