Issue with running pinefarm on Mac

[charlottehillman]

Hi,

I redownloaded madgraphs today following the cheat sheet (1-6). When I try to run pinefarm pinefarm run ATLAS_DY_7TEV_49FB_HIMASS 40000000.yaml
it seems my grids are empty and I get this error:

`INFO:

Thanks for using LHAPDF 6.5.5. Please make sure to cite the paper:

I have checked gfortran and it doesn't seem to be an issue here, but I am having trouble overcoming this error. Let me know if it would be helpful to see my .toml file or anything else. I have tried to run this with a different pinecard to see if this makes a difference and I got the same error but only the second half, starting from Traceback (most recent call last).

Thank you!

Hi @charlottehillman ,
Can I ask if you have tried just generating these events via madgraph without trying to output pineapple grids? That would help determine whether the issue is with the pineapple interface or simply with madgraph.

Did you use pinefarm or just turned on pineapple = True in the madgraph runcard @FrancescoMerlotti by the way?

[charlottehillman]

Hi @ElieHammou,

I just tried running madgraph without pinefarm. This is what I told it to generate;
import model sm generate p p > l+ l- @0 output DY_LO_7TeV launch
Apologises if this is wrong - I have never used this software before, so please let me know if I need to do it differently or feed in any files.

It seems to have given me an output which does not have blank sections as before, so looks to be working:

and as far as I can see there were no errors generated.

Let me know if this helps or if you need any more info.

Thanks!

[ElieHammou]

Yes it seems to be working by, thanks.
Also, if you have only followed the steps up to 6 and are experiencing bugs, try the steps 7 and 8 which deal with known issues.

[charlottehillman]

Okay thank you I will try that and get back to you.

Hi again @ElieHammou, I have tried these steps (7,8) and now I am getting a segmentation fault.
Installing... zsh: segmentation fault pinefarm run /Users/charlottehillman/pinetest/40000000.yaml
I had this before and made sure to make everything in my native architecture arm64 which fixed the problem, so not sure which of the steps has caused this. Sorry!
I can take a deeper look into this tomorrow.
