two-level mapping and introduced segment. 2. Segment is also the granularity of space allocation. Multiple chunks are aggregated into one segment. The default segment size can be 1GB. it only requires offset in chunk = 0, length in Chunk = 4096). If the currently segment written is not allocated, the client request the MDS to allocate segment. As mentioned earlier, segments are allocated with a default default size of 1GB (configurable >=1GB), so client requests MDS for new segment infrequently. For random write scenarios, it is possible to allocate space frequently at the beginning, but after the allocation

true Arithmetic operations with Julia's integer types inherently perform modular arithmetic, mirroring the char- acteristics of integer arithmetic on modern computer hardware. In scenarios where overflow sequencing (packets are ordered by the operating system before they are given to the application), segment size, and session setup and teardown. UDP provides no such features. A common use for UDP is in likely change each evaluation. To fix this, buffers that are specific to the task may be used to segment the sum into chunks that are race- free. Here sum_single is reused, with its own internal buffer
