Experimental analysis of state-of-the-art RDMA-based in-memory key-value stores.

• InfiniBand HCAs (Code tested on Mellanox ConnectX DDR 20 Gbps PCIe2)
• X86 Processor

• RDMA drivers (Mellanox OFED or upstream OFED)
• Memcached 1.4.37
• Redis 3.2.9
• gcc version 4.4.7

All RDMA-based systems contain two scripts ./run-servers.sh and ./run-machine.sh. Server shoud run ./run-servers.sh and client runs ./run-machine.sh. In the ./run-machine.sh, num_processes specifies the number of clients.

• Download Redis from (www.redis.io), then compile and run Redis server
• find out the InfiniBand IP address (server_ip_address) of server and initial the server keys by running ./run-initial.sh server_ip_address from client
• ports are chosen incrementally started from the default Redis listening port
• now the server is initialized
• It is assumed that system has 4 NUMA nodes with 32 cores. You can modify this by node_map and cpu_map in the run-client.sh script
• Run the script by ./run-client.sh number_of_clients test_time warmup ratio to run the experiment

• You need to download memcached from (http://memcached.org), then compile and run
• find out the InfiniBand IP address (server_ip_address) of server and initial the server keys by running ./run-initial.sh server_ip_address from client
• Run the script by ./run-client.sh server_ip_address number_of_clients
