Future changes in MPQC's infrastructure

• Exception use will be more widespread

  • Never call abort
  • Use “throw” when a error is encountered
  • All routines must be written so all temporary storage is deallocated if an exception is thrown (resource allocation is acquisition paradigm)
  • All routines must be written so pthreads locks are released if an exception is thrown
  • Issues in parallel runs have not been worked out, but since parallel runs are typically done in batch, this is not a huge problem

• Covariant/contravariant notation for index transformation operations

  • Greatly reduces confusion in matrix operations
