Hi there,

I recently added a new machine to a small condor pool at our university. I noticed that jobs were not landing on that node, and realised that this might be because its benchmark info was not fully populated so it was being deprioritised when matchmaking.

Running condor_kflops on the machine as root usually returns immediately with the output value -1
root@puck:~# /usr/libexec/condor/condor_kflops
KFlops = -1

Hi John:

Turns out, your machine is just too fast :-).  There is a bug in the way HTCondor computes the kflops, and today it overflows a counter.  We'll push a fix right away.  In the meantime, you can work around this, by replacing the condor_flops binary with a script like

#!/bin/bash

echo "KFlops = 9105849"

echo "--"

exit 0

Sorry for the headaches,
