Keating:FutureCode

• Allow the parent process in specdesign to be able to run an arbitrary command (specified in the control spec file) that re-evaluates the energy of the solution. Some ideas:
  • popen() is a useful function in C.
  • the specified command (most conveniently a script) must expect exactly one input string on the command line (the solution/backbone string) and output only one number is to stdout - the new energy.

• Get to the bottom of the apparent MPI slowdown between parent and children processes - a better timing study.
