Good Day, I have figured out, what does the exit code 128 represent? For my program, I have forgotten to bundle the necessary (implicit) dlls with it when distributing. You can also use the option /MD in Debug (or /MT in Release) when within Visual Studio 2010. This method does not require you to bundle the (implicit) dlls with your program. However, those dlls that you specifies explicitly must still be bundled. http://msdn.microsoft.com/en-us/library/2kzt1wy3(v=vs.80).aspx Thanks.

Good Day, Another issue that results in having exit code 128 is the usage of mpiexec on a remote machine that is not one of the participating nodes in the data processing. Thanks.
