Then, everything is clear. In this TCEC, they give the uci-command “Threads=43“ to Ivanhoe, which is wrong (the uci-commands are shown, when an engine plays and you click on the small gearbox-icon).
And Ivanhoe doesnt know this command... so he plays in singlecore-mode! So, it is clear, why Ivanhoe calculates only 2.5 Mn/s in TCEC 13...
Correct uci-commands would have been:
TitanicMode=true
TitanicCPUSizings=43
What a ridiculous start of this season and that nobody checked the uci-commands, before starting the season. So sad. So unprofessional.
Stephan,
Please don't speculate wildly, create misleading and incorrect topics, and throw such harsh criticisms at TCEC. That's really hurtful and incredibly unfair to those working so hard behind the scenes (cudos! to all the unprofessional volunteers) to produce this incredible exciting competition for our enjoyment.
Indoda Eziphukile provided me with some info concerning the matter. Unfortunately, he can't defend himself (and he shouldn't have to!) from any of the accusations and criticisms that abound in this topic, because like Anton Mihailov, he registered several days ago for this forum but has not yet been activated.
They are using IvanHoe9.46h 01a35 x64 (which I suggested to Anton and provided)
If you look inside (this is on my 6 core w/HT PC) you'll see that it supports UCI option 'Threads':

If the NPS reported on the TCEC web site doesn't seem right to you, I'm not surprised...it could be many factors. For ex: it's a fairly well-know fact that some info is interpreted and presented oddly by the highly customized TCEC version of cutechess.
It's should be a fun event, I really recommend you take a chill pill, relax, and enjoy the show!
