What you want would be done with: ls *.a | parallel prog -i {} -type s

This doesn't make much sense you need to tell us a bit more
background. What date? Why? Are you wanting to use parallel over many
hosts on a network, why is it important that the output files aren't
controlled by you??? Parallel runs commands in a similar way to how
you might with ssh. It doesn't require you to specify a special output
file, and STDOUT comes out how you might expect.
Best,
