函数 std::thread::hardware_concurrency() 头文件 #include <thread> 用例 unsignedlongconsthardware_threads = std::thread::hardware_concurrency(); 说明 在新版C++标准库中是一个很有用的函数。这个函数会返回能并发在一个程序中的线程数量。例如,多核系统中,返回值可以是CPU核芯的数量。返回值也仅仅是一个提示,当系统信息无法获取时,函数也会...

We first show that typical HLS scheduling constraints are insufficient to implement atomics, because they permit some instruction reorderings that, though sound in a single-threaded context, demonstrably cause erroneous results when synthesising multi-threaded programs. We then show that correct behaviour...
Describe the bug When attempting to add vectors to the index using a number of threads that execeeds the hardware concurrency as reported by std::thread::hardware_concurrency(), a crash happens. Stack trace from a test (with AddressSanit...
including the massive concurrency between different hardware modules. Recently, high-level synthesis (HLS) tools have been successfully developed to facilitate efficient FPGA design by using high-level programming language such as C and C++, and automatically compile high-level description to generate low...

The process function (lines 26–38) gets the number of available hardware threads on line 28, by calling the thread::hardware_concurrency() static method. Subsequently, it creates a vector of functors that can be used by threads, while retaining their results after the threads complete their ...
Ties among different time slots for each operation are broken using a heuristic based on the concept of force, which measures the tendency of the operation to be in a given slot, to minimize overall concurrency. The computational cost of force-directed scheduling is quadratic in the number of ...
