WHEN TWO HEADS ARE BETTER THAN ONE:
PROFESSORS PROMOTE PARALLEL PROCESSING

The Pearson twins

Professors Kenneth and Robert Pearson of BusEco's Centre of Policy Studies have developed a method of speeding up complex economic calculations.

Their software system, GEMPACK, is used to solve many of the world's biggest economic models. Complex simulations can take many hours to complete.

Modern PC's often contain two CPUs, effectively doubling processing power. The challenge is to design software that can take advantage of both CPUs at once.

"We divided the calculations into parts which could be executed independently by either processor -- so halving compute time," chorused the twins. "Faster computations will enable economists to conduct more simulations, or to solve even bigger models," claimed Robert. "Or they could spend more time playing golf," echoed Ken.
