RR means Round Robin, i.e., all threads with the same priority get
an equal amount of CPU without much delay, so the scheduler has to
switch between them quite often. RR is intended for threads that must
make some progress continuously. (See "man sched_setscheduler" and
especially "man sched_rr_get_interval".)

If you want to run a thread until it has finished for now, use
SCHED_FIFO.

I assume it is your intention that all those threads have equal priority
(which means to the kernel "don't care which one of them gets executed
first").
