  3. I use User Fortran Libraries in CFX. When I run my case in serial or local parallel mode, everything runs fine. However, when I run the case in distributed parallel mode, I get the following error message: ERROR #001100279 has occurred in subroutine ErrAction. Message: One or more user routines could not be loaded by a slave partition. Ensure the library is accessible by all hosts. What does this mean and why does this happen?

      This can happen when you use relative paths for the User Fortran Shared Libraries (relative to the *.dir run directory). If a compute node in shared parallel mode runs only slave processes, it is not guaranteed that a relative path ends up in the same location as on the compute node running the master process or the serial computation. Therefore, you must use absolute paths for the Shared Libraries instead of relative paths to avoid this error.
