Optimize short runs on compute clusters

[PascalIversen]

Description of feature

Currently, we start a job for every model fitting procedure, which is optimal for compute-intensive model fitting procedures like neural networks. For simpler models, such as naive predictors and linear models, we should consider reverting to a loop or parallel execution on a single node to avoid allocation overhang
