To see the new Midpoint integrator component in action, in student-src/components, run

ccafe-single --ccafe-rc examples/task2_rc

Feel free to modify task2_rc to assemble applications with different components. The beginning of the rc file loads the palette with all of the available components and creates an instance of each. See Chapter 2, Assembling and Running a CCA Application for further information and ideas for other “applications” you can construct.

The output should look something like this:

(3587) CmdLineClientMain.cxx: MPI_Init not called in ccafe-single mode.
(3587) CmdLineClientMain.cxx: Try running with ccafe-single --ccafe-mpi yes , or
(3587) CmdLineClientMain.cxx: try setenv CCAFE_USE_MPI 1 to force MPI_Init.
