node-compute-clusterNode.js 扩展

node-compute-cluster 是一个让 Node.js 支持跨进程分布式计算的扩展。

主程序：

const computecluster = require('compute-cluster');

// allocate a compute cluster
var cc = new computecluster({
  module: './worker.js'
});

var toRun = 10

// then you can perform work in parallel
for (var i = 0; i < toRun; i++) {
  cc.enqueue({}, function(err, r) {
    if (err) console.log("an error occured:", err);
    else console.log("it's nice:", r);
    if (--toRun === 0) cc.exit();
  });
};

worker.js:

process.on('message', function(m) {
  for (var i = 0; i < 100000000; i++);
  process.send('complete');
});
