Once submitted, all the selected calculations will be started automatically, and no further interaction by the user is required. Once each calculation is complete, Digichem will automatically analyse and parse the completed calculation results, generate any requested report and/or image files (see below), and automatically setup and submit the next calculation in the queue. Digichem currently supports the Gaussian, 50,69 Orca 71 and Turbomole 49 programs, and can handle submitting to different programs in series. In this way, a Turbomole calculation can use the output geometry produced from Gaussian, for example, as the coordinates will be formatted automatically. This process can be repeated nearinfinitely and is limited only by the resources available on the underlying cluster. In this way, computational screens of any size can be handled in an identical manner. Parallel calculation submission and resource management is handled by external queuing software, and Digichem currently supports both SLURM and PBS. Options to control shared resources, such as the amount of memory, number of parallel CPUs, and maximum job execution time, can all be configured as part of the method file. Digichem has options to ensure that the resources requested by the calculation, such as the amount of memory, do not exceed those requested from the scheduler.
