....machines, each with modest memory requirements and minor communication needs, linear equation solutions require a closely coupled system of processors with a large memory. Still, those requirements are not too onerous. For example, the recent factorization of a 140 decimal digit integer [CavallarLRLLMMZ] required finding a linear dependency among a system of almost 5 million equations in about that many unknowns, and this was accomplished in about 100 hours on a single fast processor using 810 MB of memory. This set was generated by structured Gaussian elimination from about 66 million equations ....
....of the same size, it is prudent to disregard this difference when choosing a cryptosystem. The current record in factoring a generally hard integer is that of the 140 decimal digit challenge integer from RSA Data Security, Inc. RSA 140, which was accomplished with the general number field sieve [CavallarLRLLMMZ]. Among Cunningham integers, the record is the factorization (by the same group as the one that factored RSA140) of a 211 decimal digit integer by the special number field sieve (email announcement of April 25, 1999 to [NMBRTHRY] The factorization of RSA 140 required about 2,000 MY (mips years, ....
