In Visual Studio 2022 version 17.9 Preview 1, we have introduced aMemory Layoutview, which unveils the memory arrangement of classes, structs, and unions. This feature is particularly valuable for optimizing memory layouts. Users can now visualize padding, offsets, and sizes of all...
They support parameters:D3D12_BARRIER_LAYOUT InitialLayout,const DXGI_FORMAT* pCastableFormats. They require recent DirectX 12 Agility SDK. To use them,ID3D12Device10must be available. To use non-empty list of castable formats,ID3D12Device12must be available. ...
Proper memory management in Unity can be challenging. The goal of this guide is to fit you with the necessary knowledge to profile and optimize memory consumption on any publicly available platform.

Did you ever struggle because of data structures and memory layout? For cache performance you normally want to store data in structure of arrays (SoA) or array of structures (AoS) format. AoS is usually the natural way, and it matches the way the user thinks conceptually, while SoA is usu...
Therefore the order of an object layout does not have to match the same binary sequence in C++.glz::object (compile time mixed types) std::map std::unordered_map std::pair (enables dynamic keys in stack storage)std::pair is handled as an object with a single key and value, but when...

Software Updates We update our software tools on a regular basis – on average, about 26 updates per year. Updates are optional, and you only need to download the most recent update to be up-to-date. You can set up automatic software updates using the credentials we supply to you when ...
DDP 主要基于下图所示结构,本节我们会着重讲解 distributed.py 和 reducer.cpp 两个文件。至于 backend,NCCL 已经最优化了,建议直接用 NCCL,不过 NCCL 只支持 GPU Tensor 间通信。 图8: 代码架构,原图见 [10] 终于可以看 DDP 的实现了!!首先我们贴上伪代码! 伪代码 图9: DDP 伪代码,原图见 [11] 从DDP...
