+ * These tests do increasingly complicated sets of writes followed by reads.
* POSIX standards say that any read that can be proven to occur after a write
* must include the data in that write. These tests attempt to verify whether the

*
* There are two sets of tests, one which uses POSIX i/o (fread, fwrite) and one which
* uses MPI I/O (MPI_File_read, MPI_File_write). Each set has multiple sub-tests, which
- * test varying patters of writes and reads.
