Abstract: A wind power main-shaft sliding bearing with bidirectional stresses and a wind power generation system are disclosed. The wind power main-shaft sliding bearing includes an outer ring, an inner ring and a tile block. The outer ring has an isosceles trapezoidal cross-section where the inner ring slides. The inner ring has a trapezoidal groove matching the outer ring shape. Symmetrical chutes are in two inner sloping faces of the trapezoidal groove. The tile block is in a cavity between the chute and the outer ring. The face of the tile block near the inner ring is spherical. The tile block separates first and second oil cavities, respectively near the outer and inner rings. Even when the sliding bearing is stressed with a load that deforms the inner ring, the tile block automatically adjusts the tilting angle, thereby avoiding tilting the outer ring due to operating pressure loss.

Abstract: Techniques for reducing SIMD divergence for ray tracing are provided. In ray tracing on a SIMD architecture, rays are cast into a scene. Part of such operations includes evaluating a ray cast for intersection with a triangle, which is performed using an acceleration structure. SIMD execution is performed for multiple work-items (e.g., rays) in parallel, but control flow can become divergent if the work-items need to perform different operations. During traversal, it is possible that rays require execution of an any hit shader to evaluate a candidate hit as accepted or rejected. However, if such execution is performed immediately upon detection of a candidate hit, a high degree of control flow divergence can occur, since it is likely that such execution occurs only for a single ray. By deferring this execution, it is possible to group the execution of an any hit shader for multiple work-items together, thereby reducing divergence.
