I've just installed j64-806 on my new Dell XPS 13, which does
have avx (and even avx2). Install was very smooth.
JVERSION
Engine: j806/j64avx/linux
Beta-1: commercial/2017-03-09T10:14:43
Library: 8.06.01
Qt IDE: 1.5.3/5.5.1
Platform: Linux 64
Installer: J806 install
InstallPath: /home/tages/j64-806

Multiplying two 200 x 200 matrices:
a=. 200 200$ rand 40000
ai=. %. a
ts'a mm ai' NB. mm=: +/ . *
0.004197 525568
which is 4.2 times faster than 805. This looks like a major step
forward! I'll test more later.
Thanks, Patrick
