効果があるのかな知りませんが、こんな自動チューニング機構がある。

Summary     : A dynamic adaptive system tuning daemon
URL         : http://www.tuned-project.org/
License     : GPLv2+
Description : The tuned package contains a daemon that tunes system settings dynamically.
            : It does so by monitoring the usage of several system components periodically.
            : Based on that information components will then be put into lower or higher
            : power saving modes to adapt to the current usage. Currently only ethernet
            : network and ATA harddisk devices are implemented.
 
[root@c ~]#

ただ現状は ネットワークと HDDへのカーネルパラメーター調整のみみたい。

事前にチューニングのプロファイルが用意されていて

[root@c ~]# tuned-adm list
Available profiles:
- balanced                    - General non-specialized tuned profile
- desktop                     - Optimize for the desktop use-case
- latency-performance         - Optimize for deterministic performance at the cost of increased power consumption
- network-latency             - Optimize for deterministic performance at the cost of increased power consumption, focused on low latency network performance
- network-throughput          - Optimize for streaming network throughput, generally only necessary on older CPUs or 40G+ networks
- powersave                   - Optimize for low power consumption
- throughput-performance      - Broadly applicable tuning that provides excellent performance across a variety of common server workloads
- virtual-guest               - Optimize for running inside a virtual guest
- virtual-host                - Optimize for running KVM guests
Current active profile: balanced
[root@c ~]#

インストール直後では「balanced」が選択されている

NFSサーバなマシンでは何がいいのだろうか?
ここら辺はベンチマークを取って検証すべき箇所なのですが...

[root@c ~]# tuned-adm profile network-latency
 
か
 
[root@c ~]# tuned-adm profile throughput-performance

なのかも。
計算ノードは

[root@c1 ~]# tuned-adm profile throughput-performance

なのでしょうけど
