RDMA client/server

Run a YCSB-like benchmark over RDMA to see the swapper in action.

Server (e.g., memory node)

build/bin/server

Client (e.g., compute node)

# Run with defaults (1 thread, 3M keys, 1M ops, zipfian, workload A)
build/bin/client

# Customize benchmark and swapper parameters
build/bin/client -t 1 -k 3000000 -o 1000000 -d zipfian -w A --cache-mb 100

# All options
build/bin/client --help

Hook

Let the swapper manage the memory of an application by hooking via LD_PRELOAD.

LD_PRELOAD=build/lib/liblethe.so <cmd>
