<p dir="auto">Support for RPCs having timeouts is being added in <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="521237903" data-permission-text="Title is private" data-url="https://github.com/pytorch/pytorch/issues/29601" data-hovercard-type="pull_request" data-hovercard-url="/pytorch/pytorch/pull/29601/hovercard" href="https://github.com/pytorch/pytorch/pull/29601">#29601</a>, but this isn't currently per RPC. We would like to extend this to a per-RPC timeout that is configurable by calls to <code class="notranslate">rpc.rpc_(a)sync</code>. The reason for this is that the user may want more granular control over how long they expect an RPC to last. See the discussion in the mentioned PR for some more context on the specific changes that would be needed to implement this.</p>

Per <a class="user-mention notranslate" data-hovercard-type="user" data-hovercard-url="/users/pritamdamania87/hovercard" data-octo-click="hovercard-link-click" data-octo-dimensions="link_type:self" href="https://github.com/pritamdamania87">@pritamdamania87</a>'s suggestion, we should:</p>
<p dir="auto">1.Have a timeout parameter in RpcAgent.send().<br>
2. For user RPCs, we always fill that in with the default rpc timeout.<br>
3. For system RPCs, it'll default to 0 (which would be infinite) unless the system RPC sets it.<br>
4. Later we can allow the user level RPC API to specify timeouts as well.## Motivation</p>
