Openwhisk only allows 8 invocations at a time i

[ankushshr1993]

Openwhisk allows only 8 pods to be created for n number of invocations at a time. For performance testing, we need to increase the number of pods at a time.Is this a limitation of open whisk or can configure it to eradicate this limitation

containerPool.userMemory: total memory available per invoker instance. Invoker uses this memory to create containers for user-actions. The concurrency-limit (actions running in parallel) will depend upon the total memory configured for containerPool and memory allocated per action (default: 256mb per container).

Thanks, I'll check it out.

Hi David,

As per your suggestion and described in the link I updated the mycluster.yaml file by adding actionsInvokesConcurrent: 50 but it still creates only 8 pods .I am trying to figure out what would be the value of contaierPool.userMemory: forexample for 50 concurrent pods.

I have attached mycluster.yaml file used in my deployment for your reference.I would request for your advice on this.

Regards Ankush Sharma

You need to increase containerPool.userMemory. The default value is 2048m, which corresponds to 8 pods of 256m each (the default memory size for a user container). If you want 50 concurrent actions, you have one invoker, and your actions use the default of 256m, then you need containerPool.userMemory = 50*256.

Hi David,

I have tried these values but it stil not working.Can you please have a look at mycluster.yaml file and help if I am keeping it correctly
