Descriptive Data: (report abuse)

Historically, I was most active as a siever for the Prime Sierpinski Project, the Riesel Sieve Project, and several smaller Riesel Prime Search projects. I have also done a fair amount of LLR testing for the No Prime Left Behind project.

Currently, my activity is almost exclusively via the PrimeGrid project on the BOINC platform. There I move around between the different sub-projects as my whims take me.
