More recent versions of mmfind support an -xargs option... Run mmfind
--help and see:
-xargs [-L maxlines] [-I rplstr] COMMAND
Similar to find ... | xargs [-L x] [-I r] COMMAND
but COMMAND executions may run in parallel. This is preferred
to -exec. With -xargs mmfind will run the COMMANDs in phase subject
to
mmapplypolicy options -m, -B, -N. Must be the last option to mmfind
This gives you the fully parallelized power of mmapplypolicy without
having to write SQL rules nor scripts.

Ps. Her is how to get mmfind to run some operation on the files it finds.
(I installed mmfind in /usr/local/bin)
I find this very hacky, though I suppose it is idiomatic bash
#!/bin/bash
while read filename
do
echo -n $filename " "
done <<< "`/usr/local/bin/mmfind /hpc/bscratch -type f`"
