It sounds like there's a discussion about the details coming, which is fine and good. That should maybe also have a VOTE. The debate here is then merely about what and when to call things a SPIP, but that's not important.

I don't think that was the issue that was raised; I don't advocate for investing more in supporting this cluster manager, myself. The issue was that we _already_ have support for allocating GPUs in Mesos. Whatever limited support is there, presumably, doesn't get removed. It merely needs to be attached to whatever new mechanisms are implemented. I only pushed back on the idea that it should be ignored and (presumably) left as a separate unrelated implementation. > You see that such discussions can be done in parallel.

An answer is: let's say we just make whatever support in Mesos exists still works coherently with the new mechanism, whatever those details may be. Is there any disagreement on that out there? I agree with you in that I think it shouldn't have been ruled out at this stage, per earlier comments. This doesn't seem hard to answer as a question of scope even now. --------------------------------------------------------------------- To unsubscribe e-mail: [email protected]
