Experiences (continued)
Rewrite the DNS code to make it easier to parallelize and to convert for LES (added terms in equations)
Develop a parallel code that can be converted to a serial code
Develop a code that can be easily modified since as part of ongoing research, the basic equations will undergo continual modification
Keep the code modular so that different versions of a subroutine can be implemented
Develop a code that is memory as well as CPU efficient
