Hallo Peter,

ja Ceres braucht noch Zeit und Arbeit, um sein Potential sicher auszuschöpfen.
Ceres wurde auf superschneller GPU-Hardware entwickelt und gegen Lc0 getestet.

Erklären kann ich den gravierenden Unterschied mit der Test-Hardware: 2060/3080 und dem TC 2sec/60sec.

Gleichwohl bleibt die Entwicklung von Ceres spannend.

Grüße

Lothar

Hallo Peter,

Es wird eine neue Lc0-Version für das Sufi vorbereitet, die ein Feature von Ceres beinhaltet:

FYI regarding our submission to SuFi:
• Given that it's unlikely, that Lc0 in the current configuration would win SuFi (don't let DivP fool you), it's quite likely that we'll send pr1483 binary there.
• PR 1483 is a port of one of Ceres features (parallel node gathering), implemented by Tilps.
• It gives ~+40% nps increase, at the cost of worse nodes selected (5 Elo loss at fixed nodes).
• It's also quite a tricky asynchronous code, so hang/crash-causing bugs are not unlikely -- it was tested reasonably well but only on a few configuration -- prepare for a drama.

Das klingt vielversprechend.

Danke für die Info.

Ja, auch das hier:

Another quick test PR1493 came out encouraging. This time played 204 games with a small network (703810) vs LC0263 with 30s+0.5s TC on single high end GPU: no crashes and +29 Elo (+-13). NPS improved by 35%.

Was mir hier ein bisschen fehlt, ist das Ergebnis der 108 Games. Selbst wenn ich mir einen Master unter den Teilnehmern willkürlich aussuche, bleiben Fragen offen.

Der Master wird Lc0 0.027.

Die pgn-Datei ist unter Discord/Lc0/Test-results verfügbar.

Nicht gerade aussagekräftig, 20 vs 17 Punkte.

Hallo Rainer,

ich habe den Link nicht reinkopieren können.

Auf Discord Lc0 Test discuss heute um 3:00 morgens.
