Re: [go-nuts] Does data race with only multiple goroutine parallel i=1 have an impact on the execution results?

[Robert Engels]

Sorry and the outer loop is the only reader. It probably reports it as a race though since there are multiple writers - but they all write the same value. Technically still a data race depending on if the word splits when writing.  On Jul 6, 2024, at 10:20 AM, Robert Engels <reng...@ix.netcom.com> wrote:  That is not a data race.

The problem is that I find that this code always outputs 1 on the amd64 machine, I am not sure what effect this data competition has on the execution result, whether it is an inevitable result of the amd64 machine to always output 1 or I am lucky to encounter that it is always output 1, so I ask. 在2024年7月6日星期六 UTC+8 22:20:57<Ian Lance Taylor> 写道： On Sat, Jul 6, 2024 at 7:04 AM 'qiu laidongfeng2' via golang-nuts <golan...@googlegroups.com> wrote: > > Does data race in this program affect execution results? > In amd64, it always output1. If you want to write code like this, use the sync/atomic package. Don't write code with data races.
