CUDA and cuda ProgrammingCUDA SHARED MEMORY Shared memory has some introductions in previous blog posts. This section focuses on its content. In the global Memory section, Data Alignment and continuity are important topics. When L1 is used, alignment can be ignored, but non-sequential Memory acquisition can still reduce performance. Dependent on the nature of algorithms, in some cases, non-continuous access

CUDA 5, CUDAGPU Architecture SM (Streaming Multiprocessors) is a very important part of the GPU architecture. The concurrency of GPU hardware is determined by SM. Taking the Fermi architecture as an example, it includes the following main components: CUDA cores Shared Memory/L1Cache Register File Load/Store Units Special Function Units Warp Scheduler Each SM in the GPU is designed to support hundred

Use Python to write the CUDA program, and use python to write the cuda Program There are two ways to write a CUDA program using Python: * Numba* PyCUDA Numbapro is no longer recommended. It is split and integrated into accelerate and Numba. Example Numba Numba optimizes Python code through the JIT mechanism. Numba can optimize the hardware environment of the Loca

Cuda Memory Model: GPU chip: Register, shared memory; Onboard memory: local memory, constant memory, texture memory, texture memory, global memory; Host memory: host memory, pinned memory. Register: extremely low access latency; Basic Unit: register file (32bit/each) Computing power 1.0/1.1 hardware: 8192/Sm; Computing power 1.2/1.3 hardware: 16384/Sm; The register occupied by each thread is limited. Do not assign too many private variables to it dur

CUDA 6, CUDAWarp Logically, all threads are parallel. However, from the hardware point of view, not all threads can be executed at the same time. Next we will explain some of the essence of warp.Warps and Thread Blocks Warp is the basic execution unit of SM. A warp contains 32 parallel threads, which are executed in SMIT mode. That is to say, all threads execute the same command, and each thread uses its own data to execute the command. A block can be

Summary of accelerated installation of Amber11 + AmberTools1.5 + CUDA The following installation method is based on some of the previous posts on the Forum simulated by the numerator. The installation and testing can be successful as long as the operation is correct. Considering that Amber11 is generally installed on clusters, the intel compiler and Openmpi parallel tool are used for installation. You need to purchase the Amber11 software to obtain th

The larger the number, the more parallel threads are executed, and the larger the computing workload per unit time. Buswidth = 64bit. The larger the value, the faster the data processing speed. Next let's take a look at the

In this paper, the basic concepts of CUDA parallel programming are illustrated by the vector summation operation. The so-called vector summation is the addition of the corresponding element 22 in the two array data, and the result is saved in the third array. As shown in the following:1. CPU-based vector summation:The code is simple:#include the use of the while loop above is somewhat complex, but it is intended to allow the code to run concurrently o

CUDA 3, CUDAPreface The thread organization form is crucial to the program performance. This blog post mainly introduces the thread organization form in the following situations: 2D grid 2D block Thread Index Generally, a matrix is linearly stored in global memory and linear with rows: In kernel, the unique index of a thread is very useful. To determine the index of a thread, we take 2D as an example: Thread and block Indexes Element coordinates
