- The execution of Python+MPI+EAR is not 100% automatic. Given Python is not a compiled language, the EAR loader cannot detect the MPI version automatically. Check in the User guide how to deal with this use case.
# Python+MPI
The execution of Python+MPI+EAR is not 100% automatic.
Given Python is not a compiled language, the EAR loader cannot detect the MPI version automatically.
Check in the User guide how to deal with this use case.
# Non-MPI applications compiled with MPI compilers
The EAR Loader has several methods for detecting the application use case to select the correct EAR Library to load.
When it tests whether the application is MPI, if it finds `libmpi.so` symbols it will load an MPI version of the EAR Library.
Therefore, the Library init method is called just after `MPI_Init` call function of the application, so, if your application is not calling this method, the EAR Library will not be started, and no metrics will be reported.
