Shared memory use

The index can be placed in shared memory. Using shared memory can reduce the amount of memory needed when multiple processes are using the same index. It can also improve the boot-up speed of an index for a large volume of registration data. Since changes become necessary at build time, please add the following parameter when executing "cmake" in order to use shared memory.


Note: Since there is no lock function, the index should be used only for reference when multiple processes are using the same index,
