The PPS Sieve has advanced well beyond the searches that use the sieve, and it will be many years before more sieving is needed. We are therefore suspending the PPS sieve. The CPU apps will be removed 30 days from now, on October 4th. The GPU apps will be removed, and the sieve fully suspended, somewhat later.
More information, and discussion, can be found here.
