According to the results of the latest Green500 List, IBM's supercomputers are the most energy efficient in the world.
The environmental awards organisation has been assessing the green credentials of supercomputers globally for several years, and IBM has often dominated the list.
The list shows that 17 of the top 20 most energy efficient supercomputers in the world are built on IBM high-performance computing technology.
IBM systems which have been featured on the list include Blue Gene, Power servers, System x iDataPlex, BladeCenter and hybrid clusters.
Mississippi's State University (MSU) now officially operates the most energy efficient x86-only cluster on the list, ranking ninth overall on the Green500.
According to IBM, their new iDataPlex-based cluster provides five times the performance of the university's previous, non-IBM cluster and consumes only half the power.
Trey Breckenridge, high-performance computing resources and operations administrator for MSU's High Performance Computing Collaboratory commented, "Our IBM iDataPlex cluster will allow us to accelerate the university's important research - including collaborations with government agencies and corporate entities - while minimising our power and cooling costs and taking up less space.
"This fits with MSU's environmentally conscious mission and ensures we are making the most of the university's resources."
