4.1 Parallel Execution

If a parallel version of ADF has been installed and the installation parameter hasowndirectory in the file settings is false (see the Installation manual), then all parallel processes generate and use files in the same directory. In this situation the different kids must be able to discriminate between their own files and those of other kids. This is achieved by modifying the filenames: an integer is appended with an underscore. So, rather than TAPE10 (say), we would have tape10_0 for the parent process and tape10_1, tape10_2, etc. for the kids. This does not need to bother you if you use the program run scripts provided with the package: these control execution of adf in parallel (pvm). See the Installation manual and the Examples document for more details.
