Are there legal restrictions on the use of ScaLAPACK software?
ScaLAPACK (like LINPACK, EISPACK, LAPACK, etc) is a freely-available software package. It is available from netlib via anonymous ftp and the World Wide Web. It can, and is, being included in commercial packages (e.g., Sun’s S3L, IBM’s Parallel ESSL, NAG Numerical PVM and Interactive Supercomputing’s Star-P for MATLAB). We only ask that proper credit be given to the authors. Like all software, it is copyrighted. It is not trademarked, but we do ask the following: If you modify the source for these routines we ask that you change the name of the routine and comment the changes made to the original. We will gladly answer any questions regarding the software. If a modification is done, however, it is the responsibility of the person who modified the routine to provide support.
