Alteryx Gallery only allowing one job to run at a time

Which server setting controls how many jobs can run simultaneously in the Alteryx Gallery?

This is configured through the Alteryx System Settings available on the server machine where Alteryx Server is installed.

Thank you for the quick response. We currently have "Allow Server to manage workflows running simultaneously" checked (see attached screenshot). Should I uncheck this and set it to multiple workflows? The server Alteryx is running on has 4 virtual processors, so I am surprised it is limiting us to one gallery workflow at a time.

Hi @AndyCornelissen ,

No, I would recommend leaving this option checked. That way, Alteryx will manage the resources and run the optimized number of simultaneous workflows.

Can you run this command on the server`s cmd, please? wmic cpu get NumberOfCores

Alteryx Server is licensed by physical cores and usually 4 logical cores mean 2 physical cores which is not enough to run 2 simultaneous workflows.

Appreciate the quick response. Here is the results:

C:\Users\svc_Alteryx>wmic cpu get NumberOfCores

NumberOfCores
4

Ok, that`s great! It means you have the correct number of Cores. The image below shows an idea of how the server manages the number of concurrent workflows.

Take a look at this help page to understand more what is going on. https://help.alteryx.com/20232/en/server/system-requirements.html#recommended-hardware-for-optimal-performance-6563205

One very important detail is related to the AMP engine, which is the default engine. 4 logical cores are below the minimum to use the engine, so if you leave that option checked, your server will never run more than 1 workflow due to insufficient resources. In that case, I would suggest unchecking the box and testing for yourself if the performance is being impacted.
