GPUto72 is a helper website for GIMPS. Chris Halsall set it to assist GPU users to trial factoring exponents beyond to bit level that Prime95 and PrimeNet would normally use. Because GPUs excel at factoring, it is useful to take exponents to a higher bit level, to find factors and save CPU time running L-L tests.
