Linux tuning with sysctl.conf
Hello Gurus,
does anybody have experience with linux tuning. I`m realy interesting about sysctl.conf tuning settings for batch(3d rendering, phisycs simulations, etc.) servers. Does anybody has an experience with linux tuning - I mean memory and CPU settings for heavy loaded systems. Would be great if somebody could tell me something about it. What kind of settings You have in Your clusters ? I`m working with Red Hat Enterprise 5 x86_64. |
Only got some network tweaks :
# increase TCP max buffer size setable using setsockopt() net.core.rmem_max = 16777216 net.core.wmem_max = 16777216 # increase Linux autotuning TCP buffer limits # min, default, and max number of bytes to use # set max to at least 4MB, or higher if you use very high BDP paths net.ipv4.tcp_rmem = 4096 87380 16777216 net.ipv4.tcp_wmem = 4096 65536 16777216 # don't cache ssthresh from previous connection net.ipv4.tcp_no_metrics_save = 1 net.ipv4.tcp_moderate_rcvbuf = 1 # recommended to increase this for 1000 BT or higher net.core.netdev_max_backlog = 2500 # for 10 GigE, use this # net.core.netdev_max_backlog = 30000 # TCP Port for lock manager fs.nfs.nlm_tcpport = 44865 # UDP Port for lock manager fs.nfs.nlm_udpport = 32771 |
Thanks, but I need settings mostly for CPU and memmory.
