Hi,
I admit I can not answer the question asked by upstream. The package in
question is iqtree[1] and they said that they have different
computational kernels implemented to respect different hardware.
Current Git[1] does not even build - may be due to some fine tuning of
gcc options needed???
Any help is welcome
Andreas.
