High-performance computing (HPC) initiative Petroleo Brasileiro (BR) Network was created to handle computer simulations to aid oil production in Brazil's pre-salt basin. An HPC grid was required to handle the complex project with the goal being a high-performance, affordable solution that could expand easily over the next few years. Sun, IBM, Dell, Bull, SGI, and HP were consulted. After an extensive review process, the group decided that Sun would best meet its goals for performance, scalability, energy efficiency, and cost, the latter of which was 30% less than an offering from the closest competing vendor.
