I am a retired physicist living in Tucson, Arizona. My work was in the field of low energy experimental nuclear physics, but I have always had an interest in cosmology in general and gravity waves in particular. I startd runninG the project several years ago on a 450 MHz Pentium processor running Windows 2000 several years ago and am now running three machines: 1) Intel I3-7350 4.3 Ghz CPU with GTX-750 GPU running Windows 10; 2) AMD 7550 CPU with GT-730 GPU running Windows 10; 3) Intel E5300 CPU with GT-730 GPU running Windows 10.  I am also running several other BOINC projects on these machines.
