An anonymous reader writes "The News-Gazette has an article about the troubled Blue Waters supercomputer project, providing some new information about why IBM and the University of Illinois parted ways back in August. Quoting: 'More than three dozen changes, most suggested by IBM, would have delayed the Blue Waters project by a year ... The requested changes caused friction as early as December 2010, eight months before IBM pulled out, leaving the project to look for a new vendor for the supercomputer. Documents released under the Freedom of Information Act show Big Blue and the Big U asserting their rights in lengthy and increasingly testy, but always polite, language. In the documents, IBM suggested that if changes were not made, the project would become overly expensive.'"
