This repository contains the prototype distributed in-memory key-value store evaluated in our paper. The prototype contains several different implementations of distributed transactions and communication methods which are as follows.

Distributed transactions:

• RAMP-Fast
• Three locking algorithms
• No concurrency control
• RAMP-Fast with RDMA (Our proposal)

Communication methods:

• TCP/IP over Ethernet
• IP over InfiniBand
• Send/Recv Verbs
• RDMA Write
• RDMA Write with Immediate
• RDMA Read

• GCC 4.9.3
• Boost 1.59.0
• Intel TBB 4.4
• MessagePack for C/C++ 1.2.0
• RDMA Communicaton Manager

make -j8 all

Edit server_lists/tcp and server_lists/ib for specifying server's hostname and port.

$ ./server -t TRX_TYPE -c COM_TYPE

TRX_TYPE is the parameter for specifying transaction algorithms. Supporting parameters are as follows.

• ramp_f (RAMP-Fast)
• rr, rc, ru (Locking algorithms)
• no_cc (No concurrency control)
• ac_ramp_f (RAMP-Fast with RDMA)

COM_TYPE is the parameter for specifying communication method. Supporting parameters are as follows.

• tcp (TCP/IP over Ethernet)
• ipoib (IP over InfiniBand)
• send_recv (Send/Recv Verbs)
• rdma_write (RDMA Write)
• rdma_write_imm (RDMA Write with Immediate)

$ ./client -t TRX_TYPE -c COM_TYPE -w WRITE_TRX_NUM -r READ_TRX_NUM

WRITE_TRX_NUM and READ_TRX_NUM are the parameter for specifying the number of write transaction and read transaction respectively.
