Hello,

I want to run multiple jobs at the same time on one node.
I submit these as none-blocking jobs.

But they dont run simultaneous.
I read all related posts in this forum, but cant get right of it :-(

I set following client parameters

Code: [Select]

// set the connection properties programatically
props.setProperty("jppf.drivers", "driver1");
props.setProperty("jppf.discovery.enabled", "false");
props.setProperty("driver1.jppf.pool.size", "" + jppfNumberOfConnections);

jppfNumberOfConnections is the pool size, i set it to 30 for testing.

I set the jppf.load.balancing.algorithm to nodethreads in the drivers jppf-driver.properties config file.
jppf.load.balancing.strategy is set to test, where test strategy is defined with strategy.test.size = 30.

In the node config properties file, i only changed jppf.discovery.enabled to true and processing.threads = 30.

I start one node and submit 2 none-blocking jobs, each job have a task with a sleep of 10 seconds in it.

The jobs running sequentially. Did i miss something in the config?
I have tried to find it out for hours.

Thanks in advance.

greetings
Frey

Hi Frey,

The issue here is that a JPPF node can only process one job at a time. This is the way the nodes are designed. It means that, to execute multiple jobs concurrently in your grid, you will need more than one node. However, as a mitigation you can have as many nodes as you wish on the same physical (or virtual) machine.

I hope this clarifies,
