Https://www.threadingbuildingblocks.org/docs/help/index.htmParallelizing Data Flow and Dependency GraphsIn addition to loop parallelism, the intel®threading Building Blocks (INTEL®TBB) library also supports graph parallelism . It's possible to create graphs that's highly scalable, but it's also possible to create graphs that's completely sequ Ential.In addition to cyclic parallelization, TBB also supports g

For complex practical problems, there are usually dozens or even dozens or hundreds of processes on the data flow diagram. Such a data flow diagram looks unclear. The hierarchical data flow diagram can solve this problem well. S

Continue along the 2017 Huawei Software Elite challenge to review some of the "minimum cost maximum flow" related data. This year's problem boils down to: Combinatorial optimization + minimum cost maximum flow two sub problems, a given server location to find the minimum cost maximum flow as the bottom of the algorithm

When I started to build a data center charging system, master and I said that we had to analyze the requirements before doing the system. Only by clarifying the requirements can we start the project. So let's look at it first, but I haven't seen it for a long time. Later, master said that the first part of the data room charging system is the database. This makes me even more confused. I don't even know how

A business flow chart is a chart that describes the business relationship, operation sequence, and management information flow between units and personnel in the system. It helps analysts find out the non-Confluence direction in the business flow, it is a physical model.The business flow chart mainly describes the busi
