No output from Houdini 5 :) . Another thing: where is Nalimov bases path and enabling now - nothing in UCI parameters!

Do you use the Standard Version? Then the answer is
Houdini 5 Online Manual wrote:
Houdini Pro is intended for power users with high-end hardware.
The main differences with the Standard version are:
• Houdini Pro supports up to 128 threads.
• Houdini Pro supports up to 128 GB of hash memory (131072 MB).
• Houdini Pro supports Large Memory Pages.
• Houdini Pro is NUMA-aware.
Houdini Pro can use Nalimov end game table bases.

In Arena 3.5 with Houdini 5 Pro and 6 piece syzygy, I get a single line of analysis:

Houdini 5:
1/5 00:00 67 8k +149.88 Rb5

And when I tried a simple KPK position, again a single line. But in both cases the single line does look to be winning and sufficient.

Houdini 4 has no problems so H5 is broke and needs a fix

Hi,

The problem is with Syzygy bases used.

Houdini 4 has no problem H5 does
