'Try Force HBMP Mode' in a DataFlow

Stephen Kirk

I have recently noticed there is an option under the 'High Performance Mode' in setting up a data flow that tries to 'Force the use of HBMP mode.' I was under the impression that the use of 'High Performance Mode' would have the data flow use HBMP calculation method if parameters were suitable. A few questions:

   1)   What is the purpose of this further option compared to just 'High Performance Mode'.

   2)   Can anyone provide any examples for which they would use it.

 

Thanks,

Stephen

Hi,

 

have read the Article about High Performance Mode? Dataflow execution methods: high performance in depth 

Maybe this will already answer some of your questions.

Futhermore with "Try force HBMP Mode" you can force BOARD to use the mode also the software itself wouldn't use it. In some cases you can get a faster result. This button is only visible, if you have checked "Show layout script tab" in BOARD options.

Hi Stephen, I tried to use it one or two times but the results are "puzzling": sometimes it works as you expect, sometimes it may give no result. In other words I'd say that you cannot fully control it.

I would rather suggest you, in order to improve your dataflow performance, to firstly adapt your factor cubes to the target cube dimensions (using one or two working cubes) and then apply the dataflow in standard mode in such a way that Board should run itself on HBMP mode without custom flags.

Hi Stephen,

 

In addition to Giovanni's answer (homogeneous cube structures), and related to your request for examples of how to use this function, I can give you a quick example.

 

Assuming that you want to bring one of your cubes to a lower level of detail for one of the dimensions, enabling "Try force HBMP", this will be executed with HBMP mode instead of different calculation methods.

(i.e. we want to go from Month-Product-Customer Group to more detailed Month-Product-Customer, allocating the Customer Group value equally on all related Customers, as part of a allocation driver calculation, flagging "Try force HBMP" the calculation will run much faster)

 

Hope this was helpful,

Nico
