Re: [go-nuts] Why is this code runs sequentially?
By the way, the readers of channel must not close a channel. Only writer can closes it to indicate to reader that channel is closed and nothing can be read from it. You can let channel opens (there is no resource leak), it will be garbage collected anyway. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.

Re: [go-nuts] Why is this code runs sequentially?
You want to run it concurrently, but you also need the results in order so that you can concatenate them together in the right order (I'm assuming). Something like this would do the trick: https://play.golang.org/p/lMI8rmEBJ-d On Thu, 6 Dec 2018 at 23:40, Alex Dvoretskiy wrote: > Hi Golangnuts, > > I'm trying to run SignerCrc32() concurently, but instead it runs > sequentially.

You are running it concurrently, but you're waiting for the result to arrive. SignerCrc32 runs in a separate goroutine. It takes it 1 second to return the result. During that time, the Worker for loop is waiting to read from tmpChan. When SignerCrc32 returns, the result is written to tmpChan, for loop iterates once, creates another goroutine, and starts waiting to read from tmpChan again, which will come in one second. > > https://play.golang.org/p/l5A3tBSqfs1 > > -- > You received this message because you are subscribed to the Google Groups > "golang-nuts" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to golang-nuts+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
