Problem Backbround I have a 2D array Map[Height][Width] that stores a character to represent each cell. There exists two non-overlapping regions RegionA and RegionB. Each Region is a list of unique adjacent integer co-ordinates. The number of co-ordinates in RegionA and RegionB are m and n respectively A coordinate in […]
I am experiencing the following crash in a running instance of unreal engine 4 in editor game simulation: Exception thrown at 0x00007FFD1E29551B (UE4Editor-Core.dll) in UE4Editor-Win64-DebugGame.exe: 0xC0000005: Access violation writing location 0x0000000000000010.

I'm currently implementing a neural network in CUDA, and I have a custom kernel for matrix multiplication. Here is the code I use for the matrix multiplication in my neural network: __global__ void NNFeedForwardNormalMultiple(float* __restrict__ values, float* __restrict__ weights, float* result, int inputsize, int outputsize) { int idx = threadIdx.x […]
I am trying to find out if given date is equal to dst transition date or not (either dst is starting or ending on that day). My program is as below #include "date/tz.h" #include #include template bool is_dst(date::zoned_time const& zt) { using namespace date; using namespace std; using namespace chrono; […]
I am dealing with code for a tcp client making asynchronous http requests. The code uses boost::asio: #include #include //...#include using ResolveResult = boost::asio::ip::tcp::resolver::results_type; using Endpoint = boost::asio::ip::tcp::endpoint; Quite canonically, the program defines a struct Request which handles the connection to server: struct Request { // constructor explicit Request(boost::asio::io_context& io_context, […]
The following code compiles and works fine in gcc: #include #include #include struct Class { Class() : barrier(1, [this]() { onCompletion(); }) { barrier.arrive_and_wait(); } void onCompletion() { std::cout
I stucked on a question with boost. I have a factory with ioc and method that give access to ioc: boost::asio::thread_pool::executor_type GetExecutor() { if (!m_ioc) m_ioc = boost::make_shared(2); return m_ioc->get_executor(); } I use the factory and this method to create TCP connection and use GetExecuter as constructor parameter: TcpConnection::TcpConnection( boost::asio::any_io_executor […]
Consider the following code: enum { a = 1, b = 2 - a}; void foo() { if constexpr(a == 1) { } else { static_assert(b != 1, "fail :-("); } } naively, one might expect the static_assert() to never be triggered, since the if constexpr condition holds. But - […]
