You also have to change your malloc/new and free/delete calls to cudaMallocManaged and cudaFree so that you are allocating space on the GPU. Finally, you need to wait for a GPU calculation to complete before us
Device Memory是GPU上最大的内存类型,可以被申请为普通的linear memory(类似malloc得到的内存),也可以申请为CUDA arrays。 CUDA arrays是一种为texture(纹理)特殊优化的内存系统,可以支持如线性插值等多种纹理访问方式。 类比来说,Device Memory可以类比为host上的内存条上的存贮。CPU在片内Cache都miss的情况下访问内存...

I have spent all day trying to upgrade cuda to 11.2 and get it working with pytorch. At the moment I believe I should have a fully working version of Cuda 11.2, yet I still get the following error when I try to run my pytorch code, which...

So when I run it copying data only for one work-item everything is fine. If I copy the data two times on the buffers then it fails even if I use only 1 work-item. I can't understand why. I have tried anything possible from simple malloc, new, aligned_malloc and so on. I have...
