            The thing is that, by default, once allocated heap memory size does not shrink (I mean the memory size allocated from the operating system). If your Java application at one time needed 2 GB of RAM it will keep that reserved from the operating system by default.

            If you can, try to change the design of your application to not firstly load all data into memory, but only load what you really need to do your work.

            If you really need the two big batches at the same time think about using the following Java command line argument: "-XX:+UseAdaptiveSizePolicy", which would make it possible to shrink the heap space after big memory usages.

            You can also call the garbage collector via "System.gc();", but that a) does not shrink the allocated heap memory without the suggested command line argument, and b) really, you should not think about this. Java will run it on it's own by time.

            Edit: Improved my first explanation a bit.

            Asked 2021-Mar-29 at 08:12

            I'm working on the CNN with one-dimensional signal. It works totally fine with CPU device. However, when I training model in GPU, CUDA error occurred. I set os.environ['CUDA_LAUNCH_BLOCKING'] = "1" command after I got RuntimeError: CUDA error: CUBLAS_STATUS_ALLOC_FAILED when calling cublasCreate(handle). With doing this, a cublasSgemm error occurred instead of cublasCreate error. Though the nvidia document doubt the hardware problem, I can training other CNN with images without any error.

            With searched with the partial keywords, I finally got the similar situation. Because of the stability, I used the CUDA 10.2 version. The reference asked to upgrade CUDA toolkit to higher - 11.2 in my case - and problem solved! I've deal with other training processes but this one only caused error. As the CUDA error occurred with various reasons, changes the version could be counted for solution.

            BPF filters load half word and byte of a packet. Syntax explanation required
            Asked 2021-Mar-18 at 09:13

            The following code is from BPF filters (Berkley Packet Filters). in the first line, ldh [12], it loads [12] something of a packet but documentation of BPF filter says ldh is used to load a half word of a packet and in third line it loads [23] something of a packet but documentation says ldb is used to a load byte . I like to know what is 12 and 23 along with ldh and ldb respectively.

            ...

            ANSWER

            Answered 2021-Mar-18 at 08:37

            12 and 23 are offsets into the packet. So ldh [12] loads a half word at offset 12 in the packet.

            This is referred to as the "Addressing mode" in the documentation and, in this case, the bytecode is using the "Addressing mode 1".

            This can be achieved in two ways

            1. if you want to keep the effect generic to just set what it receives, the set headlines action can set ldb::0 in payload as label and setTopics payload will set label same as id( or if you don't want label in setTopics you can check if label exists in effect then use label else id )
            2. If you don't care about it being generic, you can do something like this
