There used to be work on a BOINC F@H client, but this work has stopped
due to personnel turnover.

See:

F@H doesn't duplicate work, each WU is only assigned once by default. If
a WU has not been returned when the Preferred Deadline is reached, then
the WU is assigned to another client.

Some newer WUs are duplicate work in a sense, they verify the results of
the new SMP client & core on single CPU/core machines.

Each assigned WU is verified at upload, the information used in this
verification is stored in the queue.dat (which you can dump with qd).

See:
