Innovation Sandbox

Caliper with Accelerator Adaptor

Caliper is a blockchain performance benchmark framework which is one of the Hyperledger projects. This project, Innovation Sandbox, also uses Caliper to measure the improved performance by Accelerator. The project was generated by forking Caliper project, and a new adaptor module and smart contracts were added to utilize Accelerator.

Getting Started

Prerequisites

To use Hyperledger Caliper, you must install the following tools in advance.

• NodeJS 8.X
• node-gyp
• Docker
• Docker-compose

Installing

Install the node modules from innovation-sandbox/caliper folder via the npm executable command.

$ npm install

Install the modules for the fabric through the following command in that folder.

$ npm run fabric-v1.4-deps

Running the tests

The current version supports two benchmark scenarios, simple and smallbank which are provided by Caliper.

Move to caliper directory and run scripts/main.js with option. -c is a path to benchmark workload file and -n is a path to the blockchain configuration file.

For example, the following command executes the performance evaluation with Accelerator in 1 organization with 2 peers network.

$ node scripts/main.js -c benchmark/simple/config.yaml -n network/fabric-v1.4/1org2peeraccelerator/fabric-go.json

The command automatically downloads a docker image of Accelerator, configure Fabric network, and run benchmark tests.

Fabric benchmark test without Accelerator can be run by executing following command.

$ node scripts/main.js -c benchmark/simple/config.yaml -n network/fabric-v1.4/1org2peer/fabric-go.json

To modify test configuration, please check the Configuration File section on the Caliper website.

The test result can be varied depending on your environment.

Benchmarking your chaincode

It need to following works to run custom chaincode on the innovation-sandbox.

1. Apply batchutil to your chaincode to be compatible with the Accelerator.
2. Add your chaincode information to Accelerator configuration. The configuration file is located at caliper/network/fabric-v1.4/1org2peeraccelerator/accelerator.yaml.
3. Write a benchmark for your chaincode. please refer to the sample benchmark caliper/benchmark/custom.
4. Add your chaincode and benchmark information into the blockchain configuration file, fabric-go.json. then run the test with your benchmark.

Whitepaper
