DOSパラのスティックPC DG-STK3に
Ubuntu(Lubuntu) 15.10をインストールして簡単な性能評価．
ペリフェラルは
* キーボード SKB-SL04U
* GW-USValue-Ez
::スペック
CPU
model name : Intel(R) Atom(TM) CPU Z3735F @ 1.33GHz
cache size : 1024 KB
メモリ
MemTotal: 1984700 kB
::UnixBench
ちなみに消費電力をCHARGER Doctorで測定してみたところ
およそ 5.11V，0.4A といったところ．
動作中の/sys/devices/system/cpu/cpu?/cpuinfo_cur_freqをみてみると
1.83GHz程度まで動作周波数はブーストされるようだ．

::Stream
サイズ大き目にコンパイル
gcc -O -mcmodel=large -DSTREAM_ARRAY_SIZE=50000000 stream.c -o stream.50M.omp
gcc -O -fopenmp -mcmodel=large -DSTREAM_ARRAY_SIZE=50000000 stream.c -o stream.50M.omp
こうすると
Array size = 500000000 (elements), Offset = 0 (elements)
Memory per array = 381.5 MiB (= 0.4 GiB).
結果は，
CHARGER Doctorをみていると5.15v, 0.6-0.7A程度．
