# Bug Report Checklist

When the user sends e-mail to our mailing alias, some of the first questions we will ask are the following:

1. Have you run the BLAS, BLACS, PBLAS and ScaLAPACK test suites?
2. Have you checked the errata lists (`errata.scalapack and errata.blacs`) on netlib?

   > `http://www.netlib.org/scalapack/errata.scalapack`
   > `http://www.netlib.org/blacs/errata.blacs`

3. If you are using an optimized BLAS or BLACS library, have you tried using the reference implementations from netlib?

   > `http://www.netlib.org/blas/`
   > `http://www.netlib.org/blacs/`

4. If you are using an optimized MPI or PVM library, have you tried using the reference implementations from netlib?

   > `http://www.netlib.org/pvm3/`
   > `http://www.netlib.org/mpi/`

5. Have you attempted to replicate this error using the appropriate ScaLAPACK test code and/or one of the ScaLAPACK example routines?
