about mr accelerator question.

2016-03-16 Thread l...@runstone.com 
Hi, 
I have been present a problem in the forum,the link is: 
http://apache-ignite-users.70518.x6.nabble.com/about-mr-accelerator-question-tc3502.html
I will follow you suggestions on the ignite cluster, but i am so sorry that 
there are some confusions. 

on the single node,with 29G data, my ignite configrution is default almost.just 
modify the ignite.sh 
as follow: 
if [ -z "$JVM_OPTS" ] ; then 
JVM_OPTS="-Xms8g -Xmx8g -server -XX:+AggressiveOpts -XX:MaxPermSize=8g" 
fi 

and modify the default-config.xml 

 





























the result is very cool. 



the on-heap just 8G but the data have 29G.It work well.why? 



another problem is I start up another ignite node on the same server.I have 16g 
heap with two ignite node.My job is finished after 7 minutes, the effect is the 
same as on the single node.why the performance is not improve when add the 
memory? 

thanks

Re: Reducing memory footprint

Hi Alexander,

Are you going to have 16 node cluster and embed a client node into
application? Are you memory consumption requirements valid for server nodes
as well or only for the application? I'm asking because generally client
consumes less than server.
