NY Blue/L:Compiling and Linking On the Front End, for the Compute Nodes
First, determine whether it makes sense to port your particular application to Blue Gene/L. See Appendix A of Unfolding the IBM eServer Blue Gene Solution (September 2005).
One uses the NY Blue login node (front-end) to compile and link one's program, for running on the compute nodes (back-end). Since the login node and the compute nodes have different operating systems and processors, one must use a cross-compiler, which one invokes on the login node but which creates an executable that will run on the compute nodes.

One of ten national laboratories overseen and primarily
funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven
National Laboratory conducts research in the physical, biomedical, and environmental
sciences, as well as in energy technologies and national security. Brookhaven Lab also
builds and operates major scientific facilities available to university, industry and
government researchers. Brookhaven is operated and managed for DOE's Office of Science by
Brookhaven Science Associates, a limited-liability company founded by Stony Brook University,
the largest academic user of Laboratory facilities, and Battelle, a nonprofit, applied science
and technology organization.
