The job of the worker is to securely execute a job according to its configuration and upload results back for later processing. After receiving an evaluation request, a worker has to do the following:
- download the archive containing the submitted source files and configuration file
- download any supplementary files based on the configuration file, such as test
inputs or helper programs (this is done on demand, using a
fetchcommand in the assignment configuration) - evaluate the submission according to the job configuration
- during evaluation progress messages can be sent back to the broker
- upload the results of the evaluation to the fileserver
- notify the broker that the evaluation finished
Follows the description for RHEL-like systems which will do all steps as described in Manual Installation.
