Many of Platform Computing's more than 2,000 customers use the company's offerings to manage high-performance computing (HPC) centers used for advanced applications like materials engineering, financial modeling, and physics research.
"IBM considers the acquisition of Platform Computing to be a strategic element for the transformation of HPC into the high-growth segment of technical computing and an important part of our smarter computing strategy," said Helene Armitage, general manager for IBM's Systems Software group, in a statement.
Platform Computing's roster of blue chip customers includes CERN, Citigroup, Pratt & Whitney, and Red Bull Racing. It offers versions of its products for computing platforms from a number of major vendors, including Cray, Dell, HP, Microsoft, and Red Hat, as well as IBM.

"This acquisition will enable Platform Computing to better serve our customers by leveraging the IBM solution portfolio and extend the reach of our pioneering distributed computing software for broader enterprise adoption," said CEO Songnian Zhou, in a statement.
The deal for Platform Computing is the latest step in IBM's campaign to bolster its infrastructure offerings with applications and tools that help businesses manage so-called Big Data sets and give them greater insight into their operations to improve forecasting and planning.
