According to the protocol, engines can take upto 1 hour to do initialization.

Daniel
I don't know why they don't use a compile which allows a longer start time (if this is the main problem)? It is an easy change.
I remember very well that LC0 also had that problem with too long start time in the first months.

OTH, 1 hour of course would be no fun and no one would ever use engines really taking up
one hour for initialising.
The real network initialization takes up 30 seconds on the GPU but apparently that is too much for cutechess.

The blitz version used an approach where the initialization of networks is done after a "new" or "go" command is sent.
That means this time is counted towards scorpio's play time and will work as long as the time control is longer than the NN loading time.
The workaround should have worked but I don't think they used the correct version judging from the nemorino-scorpio log file -- it still started loading networks immediately without waiting for go/new.

This workaround works fine with cutechess-cli in my test with a fake 2 min delayed loading time as shown below.

The nemorino-scorpio log file after the restart, you can see it is still loading the NN immediately. With the workaround it should have waited
until the first go/new command. It is most likely because the wrong version is used ...

Re: what happened to scorpio NN in TCEC?

Post by elcabesa »

this is the command just added on TCEC chat by kanchess

scorpio
Nightbot : Scorpio did not crash yet and the game will eventually be replayed

it seems a problem between cpu and gpu server, from what I understood.

so please stop taking offense and start behave politely :)

They were supposed to restart without Scorpio, but they just restarted and forgot the "without Scorpio" part…
They did, but they aborted it after 3 games and re-started it with Scorpio in again, apparently with the same version they used for teh blitz test games (scorpio did 80 games without crashing even once)

What about Pirarucu? It had 3 crashes, and they said 3 crashes were disqualifying…
From what I've read, it crashed 2 times, the 3rd was a problem with something else

Again this will stall the live every time Pirarucu or Scorpio crashes (annoying), and will pollute results (unfair). Some engines will get lucky and "win" against Pirarucu due tocrashes, where they otherwise would have lost or drawn, some will not be gifted with opponent crashes.

As for Scorpio, it cannot pollute the results, because it would lose every single game regardless.
Let's hope now that things have stabilized no crashes will appear.
What has stabilized ? Nothing has been fixed. The same causes will have the same effect. Scorpio has already crashed in its 1st game. Pirarucu will crash too, unless it gets very lucky.
Scorpio hasn't crashed yet in the "new" tournament (after the restart). The loss in game 2 was due to a connection issue between the GPU-based computer and the normal one, as reported by TCEC admins (and the game will be replayed). We'll see how it goes.
