Abstract: Techniques are provided for visualizing a run of a workflow on a GUI. The techniques include: (a) rendering an origin node of the workflow at a central position and an innermost ring therearound; (b) adding to the first ring, independent nodes representing respective tasks invoked by the workflow that are not dependent on any other task in order of invocation in a distributed manner, together with edges drawn from the origin node to respective added independent nodes; (c) rendering one or more outer rings around the innermost ring; and (d) adding to each of the outer rings, dependent nodes representing respective tasks invoked by the workflow that are dependent on another task represented by another node on another ring closer to the origin node in order of invocation in a distributed manner together with edges drawn to each added dependent node from all nodes representing tasks upon which the respective task represented by that dependent node is dependent.

Abstract: A structure and method for circularizing and collimating incident light involves a substrate having first and second opposing surfaces, a first anamorphic surface positioned on the first surface and a second anamorphic microlens positioned on the second surface, the first and second surfaces being separated by a distance defined by the distance required for the first anamorphic microlens to circularize the incident light. A single microlens structure used to circularize and collimate incident light is manufactured by identifying aligned portions on opposing surfaces of a substrate, and forming microlenses on each of the aligned portions of the opposing substrate surfaces identified. The microlenses formed on the opposing substrate surfaces are fabricated from a high-index material such as GaP.
