US Patent 7712090 Parallel compiling with a serial scheduler

Methods and apparatus, including computer program products, for generating an executable program, including receiving serial compile commands in a pseudo-compiler to compile source code modules, scheduling the serial compiler commands in parallel compilers to compile the source code modules, compiling the source code modules in the parallel compliers to generate object code modules, sending compiler completion acknowledgements to a synchronizer and linking the object code modules in linkers in response to linker initiation commands from the synchronizer.
