We are inserting the final batches of work for our oldest available application, primegen. While primegen
has proved to be very useful in the early project stages for infrastructure testing, it has served it's
purpose and it's time to make way for newer, more efficient applications. Once the final batches are
completed the cleanup will be executed, finally removing old stuck workunits.

We suggest participants running primegen exclusively also select an additional subproject for future
processing. Sieve subprojects are very similar to primegen in size, so it is probably a good choice.
Once there are no more primegen work to send, we will update project for such participants to select sieve
subprojects.
