to do with this configuration.

Your timing includes the inverse, which is comparable to the cost of a
multiply I think, and is not sped up.
There are many primitives that could benefit from vector instructions.
The question is which ones to do first.

Exact memory match suggests maybe the processor doesn't support a specific avx
feature, and the code aborts to "downhandle" the operation?

I think pascal is saying he saw improvement a bit higher than I reported in
my benchmark. That is, quite a bit of overall improvement from your avx
work.

Very surprising that there is no improvement in matrix multiply, when
the processor uses AVX instructions. This processor has a large L2
cache. How large were the matrices?

on older AM A8-5500 most of the benchmark improvements (compared to 805) are
higher (minimally) than Eric reported. floating point a bit less, but float!.0
a bit more. No improvement in matrix multiply.

The first AVX hardware (early 2011) runs the JE avx binary, but only a bit
faster. Results on latest hardware is more impressive. There is some
likelihood that Intel will continue to focus on this area (vectorized ops).
Significant improvements in this area are much easier for them than in

installer updated to have an improved report when a system does not support
avx.

If you are not running jqt, loading all jqt definitions can
cause conflicts and be harmful. If you know what you are doing,
you can run
load 'ide/qt/qtlib'
which enable some qt facilities for non-Qt platforms.
Sorry for inconvenience, the changes should have happened in
j806 beta.

Yes - that's it. I just have to "require 'ide/qt/qtlib'" to get the fns I

It looks like the problem is that I work under emacs using jconsole, and
there's a switch using "IFQT" that avoids load qtlib for me.
