Abstract: An internally parallel PDES (“IP-PDES”) system performs logical processes in parallel and further performs the internal processing of at least one logical process in parallel. Because the IP-PDES system is PDES-based, each logical process may have its processing performed in parallel with the other logical processes. The IP-PDES system allows for certain logical processes to be designated as internally parallel meaning that the logical process, referred to as an IP logical process, has its internal processing also performed in parallel. The IP-DES system allocates multiple nodes for such an IP logical process so that executable code of the IP logical process executes in parallel at the allocated nodes to simulate the occurrence of an event. Internal parallelism within a PDES may help overcome resource limitations and help speed up the overall simulation.

Abstract: A stepped main pole for a perpendicular write head and methods of making the stepped main pole. The stepped main pole has a main pole tip and a base portion. The main pole tip has a surface that forms part of the ABS and a first thickness. The base portion extends from the main pole tip and has a thickness that varies from the first thickness to a second thickness to form a slanted surface with an apex angle adjacent the main pole tip. By placing the base portion away from the ABS and providing a thickness that increases in a direction away from the ABS, the stepped pole can provide the necessary magnetic flux for writing, while avoiding undesired leakage and fringing. To form embodiments of the stepped main pole of the invention, a fluorine-based reactive ion etch (RIE) may be used. By using an RIE to define the stepped main pole, the apex angle can be better controlled and tight edge control can be achieved.
