I append a referee report on your excellent paper C492: PoLAPACK: Parallel Factorization Routines with Algorithmic Blocking I would be happy to publish your paper if you addressed the changes suggested by the referee. This looks quite possible with modest extensions. Please include a discussion of your changes and their answer to the referees in your resubmittal. I thank you for your interest in Concurrency and Computation: Practice and Experience. Send us other good papers! Please send all communication -- including the resubmission -- electronically if possible using the address fox@csit.fsu.edu If you should need a "real address", please use: Geoffrey Fox Computational Science and Information Technology Florida State University 400 Dirac Science Library Tallahassee Florida 32306-4120 Phone 3152546387 Refereee Report C492: PoLAPACK: Parallel Factorization Routines with Algorithmic Blocking This is an important paper which should be published. Please discuss the impact of recent work by Dongarra on the ATLAS Scheme. Further discuss the level of effort (compsred to that done so far) to convert all the LAPACK routines. Do you expect your good results to be generally applicable?
