Hello Björn,
I have the following setup on my RPi3 :

rm ./tmp/sequencePipe_0 2> /dev/null
mkfifo ./tmp/sequencePipe_0
resctl -n 101 -c 3 -t unconstrained-server -q 1
rtspin -w -O./tmp/sequencePipe_0 -m 0 -s 1 -p 3 -r 101 -q 1 2.670000 10.000000 1  &
PID="$!"
PIDS="$PIDS $PID"
START_PIDS="$START_PIDS $PID"

rm ./tmp/sequencePipe_1 2> /dev/null
touch ./tmp/sequencePipe_1
resctl -n 107 -c 3 -t unconstrained-server -q 7
rtspin -S./tmp/sequencePipe_0 -O./tmp/sequencePipe_1 -m 0 -s 1 -p 3 -r 107 -q 7 0.100000 1.000000 $
PID="$!"
PIDS="$PIDS $PID"

resctl -n 102 -c 3 -t unconstrained-server -q 2
rtspin -w  -m 0 -s 1 -p 3 -r 102 -q 2 2.320000 20.000000 1  &
PID="$!"
PIDS="$PIDS $PID"
START_PIDS="$START_PIDS $PID"

resctl -n 103 -c 3 -t unconstrained-server -q 3
rtspin -w  -m 0 -s 1 -p 3 -r 103 -q 3 4.090000 50.000000 1  &
PID="$!"
PIDS="$PIDS $PID"
START_PIDS="$START_PIDS $PID"

resctl -n 104 -c 3 -t unconstrained-server -q 4
rtspin -w  -m 0 -s 1 -p 3 -r 104 -q 4 18.700000 100.000000 1  &
PID="$!"
PIDS="$PIDS $PID"
START_PIDS="$START_PIDS $PID"

resctl -n 105 -c 3 -t unconstrained-server -q 5
rtspin -w  -m 0 -s 1 -p 3 -r 105 -q 5 0.130000 200.000000 1  &
PID="$!"
PIDS="$PIDS $PID"
START_PIDS="$START_PIDS $PID"

resctl -n 106 -c 3 -t unconstrained-server -q 6
rtspin -w  -m 0 -s 1 -p 3 -r 106 -q 6 0.080000 1000.000000 1  &
PID="$!"
PIDS="$PIDS $PID"
START_PIDS="$START_PIDS $PID"

On completion, I get the following message: "reached end-of-file on input event stream" due to the multiple activations of the spawned jobs which in turn makes the input buffer full (INPUT_BUF_SIZE=4096).
Since I am only interested in the number of completed spawned jobs, can I trust  "st-job-stats" to give me the number I am looking for? Or does "st-job-stats" give me the number of coalesced jobs?
Best,
Jorge
P.S: Congratulations on the well-deserved 2018 ACM SIGBED Early Career Award!
