For the case of pre-order traversal, this result is shown to provide an alternate characterization that leads to a simple and elegant parallel algorithm of time complexity O(log N) with or without read-conflicts on an N processor SIMD shared memory model, where N is the total number of ...
It’s a better algorithm, right? 为了并行化实现simultaneous traversal算法,我们必须找到足够多的独立计算步骤,生成大量线程来填满整个GPU。实现这一目标的一种简单方法是深入到BVH树根节点的下面某层开始遍历,而不是仅仅从根节点开始。例如,我们可以在根节点下的第8层,确定一个含有256个节点的层作为起始,为每个...
The tree we build is not an actual data structure, but a concept we use to determine what each thread does at each step of the traversal. In this work-efficient scan algorithm, we perform the operations in place on an array in shared memory. The algorithm consists of two phases: ...
several variations ofkd-trees have been implemented on GPUs. In [19], an algorithm for constructingkd-trees on GPUs is developed. The building process adopts a top-down, breadth-first search order, starting from the root bounding box. Thek-NN implementation is based on a...
This line of thought leads to an algorithm called simultaneous traversal. Instead of looking at individual nodes, the idea is to consider pairs of nodes. If the bounding boxes of the nodes do not overlap, we know that there will be no overlap anywhere in their respective subtrees, either. ...
centralized wave algorithm, Traversal algorithms build a spanning tree: –the initiator is the root –each non-initiator has as parent the neighbor from which it has received the token first. Example: the ring algorithm, Tarry’s algorithm, depth-first search algorithm ...

traversal algorithm is not very useful, though, unless we also have a tree to go with it. In this part, we will close the circle by looking at tree building; specifically, parallel bounding volume hierarchy (BVH) construction. We will also see an example of an algorithmic optimization that...

On the other hand, it works slightly better for data-oblivious programs such as the hashing algorithm “sha”. The combination of both fares worse then just the program counter even though more information is employed. This suggests that the program counter generalizes well. On average, program-...
