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
time of the kernel function is not exactly the same. So it is recommended to use Method 3. Perform the warmup function first, in the loop 10 times the timing section. the use of NVVP and Nvprof
nvprof is a command line profiler that has been in existence since cuda5.0, and you can use only nvprof to perform some of the execution details of your code. The simple usage is as follows:
$ nvprof./sumarraysongpu-timer
You can get the following:

Use the command to start the container, sometimes sudo:

Where-P is the port mapping. You can add bash after the command, so go into the Docker shell and do something. When you nee
processor core. Therefore, the limited memory resources of a processor core limit the number of threads in each block. In the NVIDIA Tesla architecture, a thread block can contain a maximum of 512 threads.
However, a kernel may be executed by multiple thread blocks of the same size. Therefore, the total number of threads should be equal to the number of threads of each block multiplied by the number of blocks. These blocks are called a one-dimensiona

After the installation is complete, you can choose to use the command line to control Docker, or use kitematic (which can be installed separately) to handle Docker-related content using a graphical interface.
After installation, if the pull/submit mirror on the dock hub is too slow, consider registering an account with https://www.daocloud.io/and using the Docker accelerator to speed up the download/upload process.
