  • How to know which CPU kernel Linux processes are running on


    When you run HPC (High Performance Computing) programs or programs that consume network resources on multi-core NUMA processors, the affinity of CPU / memory is one of the important factors to maximize their performance. Scheduling the most relevant processes on the same NUMA node can reduce slow remote memory access. Like the Intel sandy bridge […]

  • Pytorch realizes the conversion of tensor, image, CPU, GPU, array and so on


    1. Create the tensor of Python torch.rand ((322424)) # create a random value of 3D tensor with the size of (322424) torch.Tensor ([3,2]) create tensor, [3,2] 2. The conversion between the tensors on CPU and GPU, that is, the tensors created by python b = a.cpu() # GPU → CPU a = b.cuda() #CPU → […]

  • The solution of pytorch random number generation using too much CPU


    Pytorch random number generation takes too much CPU Today, in the process of using python, we find that the CPU utilization rate is too high. After checking, it is found that the random number is generated in the CPU first, and then the. To (device) is called to transfer it to the GPU. As a […]

  • Pytorch uses CPU to load model operation mode
