Hi,

Thank you for your great job Youri.
But all version is named fizbo 2.
Why not Fizbo 2 BMI2 or Fizbo 2 popcnt or Fizbo 2 Base

Bests Regard

Here are release notes:

1. minor bug fixes: fixed a bug that occasionally crashed the engine, mostly running on multiple CPU cores. That is the bug that crashed Fizbo twice in TCEC10 .

2. minor changes to search and evaluation.

3. changes to parallel search, improving performance mostly on >4 CPU cores.

Expected playing strength is approximately 20-30 ELO higher than Fizbo 1.9
Many thanks for this version 2.0
My testing machine uses only 32 bit OS, would be nice if there's a 32bit version.

Hi Youri,

I'm using the BMI2 version on my i7-4790 Win10 PC which has 4 cores but 8 threads as I've turned on HT. I noticed a couple of things in Arena:

1) Although set to use 256MB hash the engine is showing only 4-6MB in the Engine window. I opened Resource Monitor and under Memory it shows Fizbo with 276,108 Commit (KB) but only 4,060 Working Set (KB) where:
Commit: Amount of virtual memory reserved by the OS for the process
Working set: Amount of physical memory in use by the process

While playing Fire 6.1, Fire is reporting basically the same number in both columns.

2) The NPS seemed slow at around 1,000k to 3,000k NPS. In Resource Monitor under CPU it shows Fizbo is only using 4 threads not the 8 I requested. And CPU usage is shown as 12%-13% which is only one thread. The NPS reported is more in line with single threaded engines I've used on this computer.
Again Fire shows the full CPU usage.

Could there be a problem?

Thanks,
Graham

It seems item [2] was my mistake. Somehow the Threads setting in ArenaEng.cfg had been set back to 1 from 8. Not sure how, but never mind.

I looked into the memory issue and found that Fizbo 1.9 BMI2 also did the same thing. So I downloaded the standard Fizbo2 and it too only seems to use around 5MB.

Thanks,
Graham

Here are release notes:

1. minor bug fixes: fixed a bug that occasionally crashed the engine, mostly running on multiple CPU cores. That is the bug that crashed Fizbo twice in TCEC10 .

2. minor changes to search and evaluation.

3. changes to parallel search, improving performance mostly on >4 CPU cores.

Expected playing strength is approximately 20-30 ELO higher than Fizbo 1.9
Thank you Youri! Always fun to see Fizbo go for positions other engines seem to avoid :). Here is some feedback based on reviewing many test games. First, the good news: it has been stable, with no crashes. Second, it does lose some games on time (based on 3+2 4CPU blitz games).
This includes games where F is clearly better but runs out of time despite the increment. Seems like a move overhead parameter could be helpful.

Thank you again,
Peter
