Sieving took about 1300 CPU-hours on a collection of Core2/2400 and K8/2300 cores, filtering (with -nc 1000000,1000000) was about two hours, linear algebra step about two days with four threads on a quad-core (interrupted half-way through and resumed; run such jobs with nohup, otherwise a crash of the machine running the terminal window in which you started the job). 2.5hrs per square root.
