Named in honor of its creator's Jack Russell Terrier, whose name is not actually Padolf but who nevertheless as a puppy had facial markings strangely resembling Adolf Hitler's mustache, PADOLF@home is currently the only portable, live USB implementation of BOINC, the Berkeley Open Infrastructure for Network Computing, which supports a great many non-profit distributed computing projects worldwide.
Of these projects, PADOLF@home runs two of the most scientifically significant by default: the Einstein@home project, which exists to identify and document gravitational waves emitted from objects - some of which are pulsars - in the universe using data from the LIGO gravitational wave detector; and the Milkyway@home project, which exists to build a highly accurate three dimensional model of the Milky Way galaxy using data gathered by the Sloan Digital Sky Survey.
Any computer that can boot from a USB flash drive can run PADOLF@home. Do you have an extra computer lying around at home, work or school? Use its spare CPU cycles to contribute to these projects! Unlike cryptocurrency mining, which requires expensive, specialized hardware, almost any x86-based computer made within the last 15 or so years can contribute meaningfully to these important research projects using PADOLF@home.
Standard x86 and x86-64 processors are supported, as are AMD/ATI and nVidia GPUs. PADOLF@home is NOT an "amnesiac" live USB - it is a true, fully functional portable live distribution, which means you can save your progress and shut down in the middle of a work unit when booting back into your normal OS installation.
You can write PADOLF@home to a 4GB or larger USB flash drive on Windows using Rufus, or using the following command at a Linux terminal prompt:
sudo dd if=/path/to/image5.dd of=/dev/id_of_your_flashdrive bs=1M && sync
