Dear all,

I'm new to JPPF.
I'm wondering is it possible to have a scheduler (implemented with my own algorithm) being able to explicitly decide which node does a task goes to?
For example, I'd like to do something like "I want only node A and B for Job1, others should not compute Job1".
Is it possible?

Hello,

This is exactly what you can do with an execution policy specified in the job's SLA.

You will also find in our documentation a detailed description of how to create use an execution policy, as well as a complete reference of what can be done with an execution policy.

For example regarding your current concern, let's say we have node A at IP address 192.168.1.11 and node B at 192.168.1.15, then you can limit a job to these 2 nodes as follows (we could use the host names in exactly the same way):

Code: [Select]

JPPFJob job = new JPPFJob();
// false means do not ignore case
ExecutionPolicy policy = new Contains("ipv4.addresses", false, "192.168.1.11").or(new Contains("ipv4.addresses", false, "192.168.1.15"));
job.getSLA().setExecutionPolicy(policy);
// ... add tasks and submit the job ...
I hope this clarifies.

Sincerely,
-Laurent
