I bet you all heard about make before, the wonderfully simple but versatile build tool that origins from the age of dinosaurs and that has been an inspiration for almost any other build tool out there like ant, grunt, you name it.
But it was just recently and by accident, that I got to know that you can run multiple build tasks in parallel!
Suppose you have the following Makefile:
default: build logs build: *.go GOPATH=$(PWD) go build logs: touch log/production.log
As you can get, the two tasks
log are not dependent on each other, so why not run these in parallel? The
-j2 flag tells make to use two jobs, the default is therefor
make -j2 build logs
With a little rewrite of the Makefile you can make this the default:
default: make -j2 build logs ...
