I asked about correcting doc (3.2.24 wrt pthread):

Indeed, but what wording do you suggest, that is understandable by someone
with little experience with parallel computing ?

I really like the GP notation of "#" for "number of" in eg. "#binary(n)".

Given that the reader of PARI/GP doc knows that, replace

• pthread: number of threads (unlimited, default: number of cores)

with (for current implementation)

• pthread: number of threads (unlimited, default: number of hardware threads^1)
^1 = #sockets * #cores_per-socket * #threads_per_core

One could append " (as reported by lscpu under Linux)" or not.
