....long and require about 62 times as much space, or about 3.3Gbytes per sieve processor. If one tries to use an out of core siever, it slows the computations down considerably. 7. Numerical Results The author has factored hundreds of numbers from the Cunningham project [7] and from its extensions [4]. This section gives suggested choices, as a function of the size of the number being factored, for the algorithm parameters. These have been found to work well on Pentium based processors. For other processors, with di#erent cache sizes and instruction sets, these choices may not be optimal. M = ....
