A computer-implemented method, a computer program product, and a computer system for efficient use of computing resources in two stage training of a deep learning model. A computer executes a first first-stage training job to train a deep learning model. The computer finishes the first first-stage training job by using early stopping and then registers a first second-stage training job to train a deep learning model that has been trained in the first first-stage training job. The computer executes the first second-stage training job with a small number of epochs. The computer interrupts the first second-stage training job and executes a second first-stage training job, in response to receiving a registration of the second first-stage training job. The computer interrupts the first second-stage training job and executes a second second-stage training job that has a higher priority, in response to receiving a registration of the second second-stage training job.
