With GNU Parallel you can do:

parallel myProgram (options) {} {.}.tmp ::: *.fa

From: http://git.savannah.gnu.org/cgit/parallel.git/tree/README

= Full installation =

Full installation of GNU Parallel is as simple as:

./configure && make && make install

If you are not root you can add ~/bin to your path and install in ~/bin and ~/share:

./configure --prefix=$HOME && make && make install

Or if your system lacks 'make' you can simply copy src/parallel src/sem src/niceload src/sql to a dir in your path.

= Minimal installation =

If you just need parallel and do not have 'make' installed (maybe the system is old or Microsoft Windows):

wget http://git.savannah.gnu.org/cgit/parallel.git/plain/src/parallel
chmod 755 parallel
cp parallel sem
mv parallel sem dir-in-your-$PATH/bin/
