Experiments For MSc Thesis

Purpose

This project was created for some experiments/benchmarks conducted for a MSc Thesis with title "Efficient State Machine Replication With RDMA RPCs in Java". It is uploaded here for reproducibility purposes.

The project has two parts :

1. Half round trip time (RTT/2) benchmarks.
2. A Hazelcast IMDG server that can be run until a time out.

RTT/2 Benchmarks

These are client server benchmarks that measure half round trip times. These benchmarks were made to compare RRT/2 times for :

• the DiSNI library (RDMA networking - SEND/RECV)
• the jRCM library (RDMA networking - SEND/RECV)
• TCP Java NIO sockets

The classes used to execute the benchmarks are :

• DiSNI benchmark - jarg/thesis/experiments/benchmarks/disni/twosided/TwoSidedBenchmark.java
• jRCM benchmark - jarg/thesis/experiments/benchmarks/jrcm/twosided/TwoSidedBenchmark.java
• TCP NIO benchmark - jarg/thesis/experiments/benchmarks/javanio/NioBenchmark.java

These classes contain comments on how to run the benchmarks.

For the DiSNI and jRCM benchmarks configure the rdma.bench.properties file in src/main/resources/. The file has comments explaining the configuration parameters.

Hazelcast Server

You can use the src/main/java/jarg/thesis/experiments/benchmarks/hazelcast/TimedHazelcastInstance.java class to run a Hazelcast server until a specified timeout. To configure the server, use the hazelcast.xml file in src/main/resources/.
