A portable set of linear algebra subprograms for use on a vector computer with an attached fast secondary storage device has been developed. The set currently contains routines for matrix multiplication and for the solution of block tridiagonal, symmetric and positive definite, and general systems of linear equations. Main matrices are stored on the external device in blocked form, and block matrix techniques are used throughout. Performance data are presented which demonstrate that the speed of the routines approaches that of routines with all data in main memory and is close to the maximum speed of the processor.
