Systems and methods are disclosed herein, including those that operate to prefetch a programmable number of data words from a selected memory vault in a stacked-die memory system when a pipeline associated with the selected memory vault is empty. Specifically, the game program is converted into a transfer file at a level \u201c1\u201d of the nested structure, and a transfer file n\u22121 converted at an immediately lower level \u201cn\u22121\u201d and the game program are converted into a transfer file at a level \u201cn\u201d. The trimmable open centerbody may be used to compensate for production tolerances making it possible to obtain the desired core effective area for proper engine operation. We experimentally demonstrate the system by making movies of laser induced shock waves with a temporal resolution of 5.
