The “poster child” use case is for a counter to be on one image and various other images increment the counter with atomic_fetch_add operations. None of the participating segments require ordering with respect to each other. This is a core part of the parallel integer sort algorithm." ...
Unless you have the weapons and the ammo to just spray everyone again and again as you leave and come back to specific sections of the map, this makes exploration more annoying and too difficult to attempt. Add on that the cameras will raise the alarm and call enemies to them and that ...
fetch_and_add(x, 1) I assume thatfetch_and_add()andload()are atomic operations based on the corresponding hardware instructions. As you may notice, nothing is locked here. Multiple threads that call those functions concurrently can all make progress. The atomicity ofload()makes sure that no...
如何将其视为一系列 std::atomic<uint64_t> 对象? 最终目标是将64位变量的数组放置到共享内存并执行 __sync_fetch_and_add (GCC内置)这些变量。但我更愿意使用本机C ++ 11代码而不是使用GCC内置。那么如何将分配的内存用作STD ::原子对象?我应该邀请 placement new 在512个柜台上?如果什么 std::atomic在...
“Torwald, fetch the gear you’ll need for a ground expedition. Send the Vivers out first to scout for his trail. Send Homer, too. He can see and sense things we can’t. Take everybody who isn’t needed to repair the AC. When that’s fixed, it’ll be a lot easier looking. ...
