Dec 28, 2009 · To me contention is a competition between 2 or more threads over a shared resource. Resource can be a lock, a counter etc. Competition means "who gets it first". The more threads the more contention. The more frequent access to a resource the more contention.
May 20, 2020 · "Contention" usually refers to the situation where two or more threads need to lock the same lock. We say that the lock is "contested" or maybe, "heavily contested," if there is a significant probability of any thread being forced to wait when it tries to acquire the lock.
The cost of opening a file, discarding all its contents, and closing it over and over might not sound like much, but for a large header included transitively by hundreds of other headers (e.g. windows.h, the low-level stuff providing simple type definitions like stdint.h, types.h, etc.), the difference between opening it exactly once per source file and opening it a hundred times (where only ...
Jun 12, 2014 · #define T 100 Whereas in C++ examples, it is almost always: const int T = 100; It is my understanding that in the first case, the preprocessor will replace every instance of T with 100. In the second example, T is actually stored in memory. Is it considered bad programming practice to #define constants in C++?
Jun 8, 2011 · #define MY_MACRO printf( \ "I like %d types of cheese\n", \ 5 \ ) But you cannot do that with your first example. You cannot split tokens like that; the << left-shift operator must always be written without any separating whitespace, otherwise it would be interpreted as two less-than operators.
Mar 2, 2019 · Replication reduces both latency of access and contention for a read shared data item. My interpretation is that replicating data to local caches allows multicore processors to reduce latency (because of data locality - the data is significantly closer to the processor). I agree with that portion.
Mar 11, 2014 · #define mkstr(s) #s mkstr(foo) // is the same as "foo" So in your case, #define PROJX(id) "..\\" #id "_data_var.h" #define PROJ(id) PROJX(id) #define PROJECT PROJ(ID) might be one way to go. Another alternative is. #define mkstrX(s) #s #define mkstr(s) mkstrX(s) #define PROJECT "..\\" mkstr(ID) "_data_var.h" which does the same, getting a result of
Jun 30, 2016 · So-called lock-free algorithms tend to use tight busy-waiting with a CAS instruction, but the contention is in ordinary situations so low that the CPU usually have to iterate only a few times. So-called wait-free algorithms don't do any busy-waiting at all.
Creating a truly compile-time generated constant dictionary in C# is not really a straightforward task. Actually, none of the answers here really achie
