I've recently discovered LittleBlitzer, is a great tool for testing, but I found the "ponder" check disabled in the tournament options.
I find this option very interesting to measure how well implemented is the hash table.
I'm currently using version 2.72. Is there any version with this option enabled? If not: When we'll find a new version?
Thanks in advance.

A possible solution with Ponder 'on' in LittleBlitzer.
¡Hola Alberto!
I have just tried a thing with LittleBlitzer 2.5 (which should not be very different to 2.72 version): it is related with Engines.lbe file. What I do is the following:
a) I open a Notepad and I write the parameters of the engines (I learned that from Readme.txt file and some looks to ImmortalChess Forum); here is an example:
b) Here is where I add 'Ponder on'. Then, clicking in 'File\Save as...' you change the name to "Engines.lbe" (please do not forget the " " for changing the extension of the file: from *.txt to *.lbe) and save it in LB (LittleBlitzer) folder. Well, obviously you have to change the paths of the engines (I tried two renamed StockFishs for simplifying the paths).
I try this Engines.lbe file with the Task Manager opened, and each engine used more than 25% (more than one core) in an Intel i5-760 (4 cores), so it should works fine. If anyone has a better idea, please post it. ¡Buena suerte!

The GUI ponder on feature was never implemented, sorry Modifying the engines file is indeed the way to do it.

But the GUI must send a "go ponder" command to the engine, doesn't it? So modifying the engines file won't work.The GUI ponder on feature was never implemented, sorry Smile Modifying the engines file is indeed the way to do it.
Ok, I'll try with a greater time control to test my TT.
I supose i have to wait until version 3.0
Thank you Nathan.
(and of course, thank you for your tool)

Re: A possible solution with Ponder 'on' in LittleBlitzer.
Ah yes you are correct... the engine in question must not be following the UCI standard properly. Pondering was never a big priority as the aim was to get many threads running at once to use all CPUs.
Also sorry for the lack of new versions lately, I have been side tracked with another project
