The project could use a larger value for <version_select_random_factor>:

If the project sets <debug_version_select> they'll see info in
the scheduler log that will clarify what's happening.

Since the message below I have found the below config_aux entry. I have asked the
project admin what values he has set. Other users have suggested its taking 1024
tasks before trying a different app. Other than this is there anything else the
project admin can do so it tries the various apps more quickly?

In predicting which app version will be faster for a given host, multiply
the
projected FLOPS by a uniform random variable with mean 1 and this standard
deviation (default 0.1).

*Subject:* *Project app selection reset*
I have an issue with Asteroids where the project app selection doesn’t work
properly. They have 3 period search apps for the CPU, being sse2, sse3 and avx.
All my x64 machines support avx as the highest instruction set available from the
project. I have 4 identical Ryzen 7 Machine, two of which have received and are
running the avx app. One got the sse2 and another got the sse3 app. None of them
have tried the other apps according to the application details for each host.
Its not limited to AMD, I also have 8 i7’s-6700’s again identical builds and its
a similar story. Six got the avx app, one the sse2 and the other one got the sse3
app. Again no history of trying the other apps to determine the one with the
highest APR. For these two “slow app” machines I have detached them from the
project and am waiting on their 90 days of no contact before I can delete the
host before reattaching it in the hope a new host record will start with the avx app.
Is there any way to get it to try the other apps like its supposed to, or at
least to reset the host app details? I have contacted the admin, Kyong but he
isn’t aware of anything he can do. I have also seen other people on their message
boards complaining of the same problem.
