By that do you mean the Apache processes themselves would be MPI processes? If that's the case I doubt if anyone has done that, serving web pages is very much an embarrassingly parallel type application so it's likely to be far more efficient to run the head node of the cluster as a reverse proxy/load balancer and use the compute nodes as individual web servers to service those requests. There was a similar query on the Apache users list back in 2010 which was answered along the same vein: http://www.gossamer-threads.com/lists/apache/users/389857 If you wanted to get this going as a toy project yourself then you may find it better to instead try and run the cluster as a single system image (SSI) using something like OpenMOSIX, OpenSSI or Kerrighed instead. That way you won't need to modify Apache and they (should) try and migrate the prefork processes around to load balance. Note that I have no idea if any of those 3 projects are still actively developed.. Best of luck!
