Abstract: Disclosed is a method for enhancing memory utilization and throughput of a computing platform in training a deep neural network (DNN). The critical features of the method includes: calculating a memory size for every operation in a computational graph, storing the operations in the computational graph in multiple groups with the operations in each group being executable in parallel and a total memory size less than a memory threshold of a computational device, sequentially selecting a group and updating a prefetched group buffer, and simultaneously executing the group and prefetching data for a group in the prefetched group buffer to the corresponding computational device when the prefetched group buffer is update. Because of group execution and data prefetch, the memory utilization is optimized and the throughput is significantly increased to eliminate issues of out-of-memory and thrashing.

Abstract: A screen-touch-control electronic device for providing medical information includes a communication module, a memory module, a control module and a touch screen. The communication module is in signal connection with at least a server to download patient information. The patient information are selected from the group consisting of patient abstracts, medical records, medicine records, laboratory data, doctor orders and medical image information and any combination thereof. The memory module stores a medical information application program and the patient information downloaded through the communication module. The control module electrically connects with the communication module and the memory module, and performs the medical information application program to generate an information window. The touch screen electrically connects the control module, displays the information window and detecting a touch event to generate a touch signal.
