To test if the installation works, do
in the romio/test directory. This calls a script that runs the test
programs and compares the results with what they should be. By
default, make testing causes the test programs to create files in
the current directory and use whatever file system that corresponds
to. To test with other file systems, you need to specify a filename in
a directory corresponding to that file system as follows:
make testing TESTARGS="-fname=/foo/piofs/test"
