Who wrote/contributed to ATLAS?
Note that this question addresses package design and code contribution, not money, infrastructure or testing. R. Clint Whaley founded the ATLAS project. After the initial release, he was joined on the project by Antoine Petitet. Between them, these two individuals are responsible for 95% of the code in ATLAS, along with pretty much all of the design. That is not to say that others have not made substantial contributions, however. In particular, ATLAS has been designed to allow for outside contribution such that a user can provide only a very small kernel, and thus speed up large portions of the library. Many people have contributed in this manner, and this has resulted in extremely large performance improvements for ATLAS on certain architectures.
