Description
Currently, we expose a very low-level interface for allocating memory - as shown in this documentation:
rdmalib::Buffer<char> in(opts.input_size, rdmalib::functions::Submission::DATA_HEADER_SIZE), out(opts.input_size);
in.register_memory(executor._state.pd(), IBV_ACCESS_LOCAL_WRITE);
out.register_memory(executor._state.pd(), IBV_ACCESS_LOCAL_WRITE | IBV_ACCESS_REMOTE_WRITE);
While rdmalib::Buffer is applicable, we need a higher-level concept based on the CX++ std::allocator to integrate RDMA-managed memory into user applications.
- Add allocator implementation in
rfaaslib. - Encapsulate the memory registration in
rdmalib- provide generic enums for local/remote read/write ops + atomics. - Support in allocator registration and deregistration of memory.
- Add test demonstrating standard memory allocation.
- Add test demonstrating allocation with
std::vectorand our custom allocator.
