Paul Leyland, who has been involved in most of the important factoring
achievements, estimates that the size of the project with today's
hardware would be comparable to the RSA-129 effort, which in 1994 found
the factors of that 426-bit number using 1600 distributed computers
(about 5000 MIPS-years). He expects such a project to be completed
within a year or two.
By comparison, Paul estimates that factoring a 768-bit RSA modulus would
currently require an effort about the size of the Apollo project.
