Rice University Making advancements in biomedical research for the betterment of mankind

The need: Rice University wanted to remove computer-related constraints from its researchers to support groundbreaking work in biomedicine and related disciplines.

The solution:

The university partnered with IBM to implement BlueBioU, a high-performance computer based on IBM POWER7® processors. The applications running on it were optimized by IBM XL C/C++ and XL Fortran for Linux compilers.

The benefit:

§  Rapid transition of applications to IBM Power Systems and optimized performance using XL C/C++ and XL Fortran for Linux

§  Increases the speed at which complex applications can run by up to 26 times

§  Simplifies management of IT resources on campus through centralization and consolidation

§  Frees researchers from having to maintain their own IT systems, allowing them to focus all their attention on the research

“As soon as you start tuning with the IBM compilers, you get better performance from just about any

application,” says Andrews. “Researchers would rather not spend time tweaking the code.

They can let the compiler do it for them.”

Solution components: §  IBM Power®750 Servers

§  IBM POWER7® processors
