Speed of computers
==================

I was in  the Prague last week. I  had only the GPD Pocket  with me (an
Item Atom-based  machine). I did  some light computing here  (some FEA)
and  found  that speed  on  my  unoptimised  software is  still  rather
acceptable here. After return I tried to do the same on the MNT Reform.
As expected the MNT was about 2  times slower (it has an industrial ARM
CPU which is wasn't the fastest even when it was new).

Interestingly my POWER9 machine was just about 3x times faster that the
GPD (the problem was too small to use all 16 available CPU threads so I
used  just 4;  the same  amount as  number of  cores on  the other  two
machines).

Now I am  siting in front of my  SGI O2 and waiting for  results if the
same  computation. It  is not  necessary  because I  can just  transfer
result file from  any of faster machines  but I am curious  how fast it
will be (it's already on 10 minutes; the fastest time was 52s).

Of course, the O2  has much harder job as I also run  the XMMS, a bunch
of terminals with  various apps and more.  And there is only  a 250 MHz
MIPS R10000  CPU.
