Does SETI@home and BOINC for that matter support the SPARC T4 RISC processor? I've thought about getting a RISC server now and was wondering if BOINC or SETI even supports the SPARC processors as I know they're pretty uncommon for volunteer computing.

SETI@Home does not appear to have an "offical" Sun/SPARK application. https://setiathome.berkeley.edu/apps.php

Other, independent, developers may have ported the current application to Sun/SPARK., it would be worth asking the question on SETI's own message boards - either in the Q&A section https://setiathome.berkeley.edu/forum_help_desk.php or in "Number Crunching" https://setiathome.berkeley.edu/forum_forum.php?id=10.

As far as I know, no one is porting over BOINC or any project to the SPARC at this time. You may be able to find a very old BOINC (5.x.x) via third party sites, but then you run into the problem that no project has an up-to-date application for it. The applications that may be available, also built by third party, are out of date and no longer used.
