Webb27 feb. 2024 · CUDA applications can use various kinds of memory buffers, such as device memory, pageable host memory, pinned memory, and unified memory. Even though these memory buffer types are allocated on the same physical device, each has different accessing and caching behaviors, as shown in Table 1. WebbHost pinning enables you to “pin” an XS advanced application to a particular set of hosts that have been assigned the role xs_worker. In this way, you can control where applications run and ensure they can only be run on a particular host or in a specific space. Pinning applications to a particular host provides the following benefits: Isolation
