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.
