Hi,

I'm using the command brainController.py to run a graph, but when I run it it's only utilizing 1 thread on the server.

None of the parameters seem to control the number of threads. There's -P option, but I can't find any documentation of what properties are available to reference.

Any help would be awesome.

Thanks.

There are two ways to do this, but both of them involve setting the parameter ls.brain.controller.farm

If want to set the parameter for all graphs, then look in {lavahome}/conf/ls_brain.prop

In ls_brain.prop, it takes the form:
ls.brain.controller.farm=("localhost:7721:8")
Another way to set this is via an environment setting:
export p_ls_brain_controller_farm='("localhost:7721:8")'

The three parts of this parameter are: [hostname or IP]:port:threads

There's a deeper discussion necessary if you use more than one server in the farm at once.

I tested both of those and they both worked in our setup.

Appreciate the quick response.

Hi,

Whats the format if I have 2 servers in a farm?

Is it something like...

ls.brain.controller.farm=( "mdsrdsrv01:7721:2,mdsrdsrv02:7721:2" )

Or is there a little more to it?

It seems to work.

thanks

Hi,

Further to our MDA discussion the other day, inorder to balance out the nodes in a round-robin fashion we would declare our farm as follows;

ls.brain.controller.farm=( "mdsrdsrv01:7721:1,mdsrdsrv02:7721:1,mdsrdsrv01:77 21:1,mdsrdsrv02:7721:1" ).

With this we can get a greater spread of threads/drones running in the farm.

Does a service or server need to be restarted for a change in ls_brain.prop to take effect? I'm modifying the ls.brain.controller.farm=("localhost:7721:8") parameter.

Please provide specifics here so that I can provide this information to my server admin.

Thank you,
