inception and scaling with OpenFaaS

[mkomu]

We are trying to run inception function on Intel based devices on
OpenFaaS (one master, one slave). We are have not been able to scale
it out. Wondering if this is general problem with OpenFaaS or just a problem with this function.

Expected Behaviour

Expecting that if inception is called multiple times that OpenFaaS would start scaling it out.

Current Behaviour

Apparently the alert manager scales only when it detects many (short?) function invocations per second. However, in this case, the inception function executes for several seconds and, hence, alert manager fails to scale out.

Steps to Reproduce (for bugs)

Just following inception function instructions and invoking it several times.
