run job chain parameter-depended on different slaves at the same time

[Lampe, Ingo]

Hello,

 

I have the following  problem

 

 

1 jenkins master (1.625.3)

 

2 windows 7 slaves ( connected and started over JLNP):

-        slave1

-        slave2

 

3 job: (TestStarter -> FlashEcu -> TestEcu)

 

 

	DownstreamTrigger of Job Test_Starter	DownstreamTrigger of Job FlashEcu
master| Test Starter	Slave1 | FlashEcu	Slave1 | TestEcu
	Slave2 | FlashEcu	Slave2 | TestEcu
	…	..

 

 

the job will be triggered on the special slave depending on the parameter CurrentVariant(Variant1-3 runs on slave 1,Variant4 runs on slave2)

 

This work generally fine but the test takes much time, so it would be nice if the test job(FlashEcu & TestEcu) can run parallel on the 2 or more slaves.

 

I have tried it with the Throttle Concurrent Build plugin, but it worked not really parallel the FlashJob will be blocked till it has ended.

 

Can anyone help me or give me a hint?

 

Best Regards

 

Ingo

Hello,

sorry some additional informations.

 

I tried to realize this mainly with this plugins:

 

- NodeLabel Parameter Plugin

- Parameterized Trigger Plugin

Hi Ingo,

 

First:

Do you have more than one executor per slave? If not, it is not possible for Jenkins to start more than one job.

 

Second:

The fact that Jenkins never starts two absolutely identical jobs was recently discussed in this group and is also mentioned on the Throttle Concurrent Builds wiki page: https://wiki.jenkins-ci.org/display/JENKINS/Throttle+Concurrent+Builds+Plugin This may be your case if your builds are started with exactly the same parameters. For resolution please search the history of the mailing list.

 

Regards

Eric

Hi Eric,

thank you for your Response.
It is not quite the same scenario you described.

First:
master: 2 executors
slave1: 1 executor
slave2: 1 executor

Maximum Total Concurrent Builds=2 or 0
Maximum Concurrent Builds Per Node=1

slave1 and slave2 in group Test_PC_Group1.

The job Test_Starter is restricted to run on the master
The jobs(FlashEcu,TestEcu) are restricted run on Test_PC_Group1.


Seond:

the build has not identically parameters:

there is a Parameter called Current_Variant which can be Variant 1 - Variant 4.
FlashEcu (Variant1,Variant2,Variant3) runs on slave1
FlashEcu (Variant3) runs slave1

dependend on this value in the Job preparation section will be set  the parameter Exeucting_Slave which which is the node where the downstream job should run.

Executing_Slave=slave1 or slave2

On triggering the the downstream build this parameter will given as NodeLabelParameter to the doenstream job (FlashEcu).

So the Scenario is

master                          Slave1 Actual Build        Slave2 Actual Build           Slave1 next Build         Slave2 next Build
TestStarter[Variant1     ->Flash Ecu[Variant1]                                                  ->TestEcu[Variant1]
TestStarter[Variant4                                            ->Flash Ecu[Variant4]                                            ->TestEcu[Variant1]

only on execution per slave is needed, but the job chain (flashEcu->TestEcu)  per node must be run complety !!!

So is it Possible with this plugins:

- NodeLabel Parameter Plugin

- Parameterized Trigger Plugin

- Throttle Concurrent Builds Plugin

- EnvInject Plugin

If there is a working solution please give me hints to solve it.

It would be very nice  this can be later adpated with matrix builds ( plugins installed but jobs not matrix-configured).

Thanks in Advance.

Best  Rregards
Ingo
