Parallel loop support

[adalyn]

Parallel loops are supported by LabVIEW but not LabVIEW FPGA, this requires us to copy/paste the same blocks multiple times to make them run in parallel.  I would like to see the ability to use parallel loops on FPGA targets as FPGAs are very well suited to this style of programming and the current copy/paste parallelism hinders this.

This would be a big advantage to run reentrant subVIs parallel without copy the subVIs.

This is the biggest pain with high channel SCTLs and fully support this! I tried to suggest it as loop unrolling but this description and syntax would make more sense

The most useful programming structure on FPGA is parallel execution. I do not understand why this pretty nice notation with "parallel for loops" is available on the host system but not on the FPGA. I have so many cases where the notation would perfectly fit but I have to write it all out and when changing the array size I have to go through all code. NI, you need to give a very good reason to refuse this structure on FPGA or are you just too lazy to implement it 😉 (or do you get payed by the miles of wires we are drawing on the vis?). 

programming languages are about how nicely you can express a code!

I would love this feature!

The best workaround I have at the moment is programming what I want in VHDL and then making an IP block to implement it in LabVIEW. But if I have already programmed up the maths in LabVIEW then I cannot use this work in the VHDL, I have to port the code to VHDL before building the IP.

I would love this feature!

It looks like I will have to learn how to program HDL blocks and pull them in as this in not currently supported. 

I asked the same basic question here. https://forums.ni.com/t5/LabVIEW/Automating-Parallelization-in-LabVIEW-FPGA/m-p/4185946?profile.lang...

This is similar to what LabVIEW FPGA IP Builder supported pre-2020: https://zone.ni.com/reference/en-XX/help/371599P-01/lvipbuilder/lvipbuilder_tutorial/

See 2020 release notes where it was deprecated: https://www.ni.com/pdf/manuals/374737l.html

Any idea why this was pulled out? I asked a similar question at the link below, it looks like that would have been a good way to solve it. I wonder if it is worth back-tracking to 2018 for?

I would not back-track because then you have no upgrade path.
