DEX: Scalable Range Indexing on Disaggregated Memory

What's included

• DEX - Proposed distributed B+-Tree on disaggregated memory
• Benchmark framework

Building

Dependencies

1. We tested our build with Linux Kernel 6.3.2 and GCC 13.1.1.
2. Mellanox ConnectX-5 NICs
3. RDMA Driver: MLNX_OFED_LINUX-5**
4. memcached (to exchange QP information)
5. cityhash

Compiling

Assuming to compile under a build directory:

git clone https://github.com/baotonglu/dex.git
cd dex
./script/hugepage.sh
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release .. 
make -j
cp ../script/restartMemc.sh .
cp ../script/run*.sh .

Running benchmark

1. configure ./memcached.conf, where the 1st line is memcached IP, the 2nd is memcached port
2. In one server, execute ./run.sh
3. In remaining servers, execute ./run_other.sh
