device_mem_info

arrayfire_wrapper.lib.device_mem_info() → dict[str, dict[str, int]]

Returns a map with the following fields:

• “alloc”: Contains the map of the following

  • “buffers” : Total number of buffers allocated by memory manager.

  • “bytes” : Total number of bytes allocated by memory manager.

• “lock”: Contains the map of the following

  • “buffers” : Total number of buffers currently in scope.

  • “bytes” : Total number of bytes currently in scope.

Note

ArrayFire does not free memory when array goes out of scope. The memory is marked for reuse. - The difference between alloc buffers and lock buffers equals the number of free buffers. - The difference between alloc bytes and lock bytes equals the number of free bytes.
