node-lar-multiply-rest

A simple REST module that performs sparse matrix multiplication through WebCL/WebGL for the LAR/LAR.js project

Requirements

• node-webcl (patched version)
• express
• gzippo
• winston (logging)
• mocha, should (testing)

Installing

1. Clone this repository
2. Enter the repository directory
3. npm install OR CPLUS_INCLUDE_PATH=$OPENCL_INCLUDE_DIR npm install

Note that if you incur in some problems, they might be related to the module requires "node-webcl": you need to install also its own dependencies that don't get installed automatically (read here)

Startup

Start server with npm run-script run (with default arguments)

OR

Start server with ./startREST.sh (*NIX flavour) or node RESTMultiply.js. Possible arguments:

• --no-webcl (disable WebCL backend) Default: false
• --cluster (enable cluster). Default: false
• --port=1234 (use port 1234 to serve request). Default: 3000
• --key=dln (use string "dln" as api key for this instance).

REST Endpoint

The REST endpoint is (with a proper HTTP POST)

• http://HOST:PORT/service/APIKEY/multiply

or

• http://HOST:PORT/service/APIKEY/multiplyCOO

The latter has the effect of using a OpenCL kernel that performs CSR*CSR = COO. (Untested)
