weishy-xun opened a new issue #9474: how to release gpu memory in the garbage pool?
URL: https://github.com/apache/incubator-mxnet/issues/9474
 
 
   As I can searched,  there're a lot of issues about gpu memory leaking, and always end with something like:
   
   > Memory isn't really 'leaked'. It's released to a pool. The pool will only be emptied when an allocation returns out of memory.
   
   However, when I use multiprocessing,  it is really painful,  because the "pool" isn't share between process. E.g. I have 4 processes, one ocuupied 11g, when another process get "out of memory", it cannot release the first process's garbage pool. And if I do not call the first process forever, the garbage will be there forever. Is there any method to release memory manually? Or can I set a memory limitation for a process?
