Support for ScaLAPACK

ScaLAPACK, Version 1.6

Technical questions should be directed to the authors at

Please tell us the type of machine on which the tests were run, the compiler and compiler options that were used, details of the BLACS library that was used, as well as the BLAS library, and a copy of the input file if appropriate.

Be prepared to answer the following questions:

  1. Have you run the BLAS, BLACS, PBLAS and ScaLAPACK test suites?
  2. Have you checked the appropriate errata lists on netlib?
  3. Have you attempted to replicate this error using the appropriate ScaLAPACK test code and/or one of the ScaLAPACK example routines?
  4. If you are using an optimized BLAS or BLACS library, have you tried using the reference implementations from netlib?
