Can MadSpin run on a cluster?

Hi,

Madspin, is not able to run in multicore/cluster and will automatically run in single core on your main computer.
Actually the crash that you get comes from MadWidth [arXiv:1405.0301] which is used to compute the partial width
since you did not include those in your param_card.

That program supports the cluster submission for it’s computation but looks like one step fails on your cluster.
Do you have a central disk for all your node?
Do you succeed to run on your cluster
generate p p > t t~
output
launch

Cheers,

Olivier

Hi

It was t t~ events that I was generating. I don't think there is a problem with the cluster, I think it's like you said and it fails on the MadWidth part. If I don't select the MadSpin module to run, the whole thing will continue without any glitches.

Cheers,
Rob

> It was t t~ events that I was generating.

Not exactly, you are running at NLO and not at LO and the step on the cluster are not exactly the same.
MadWidth is a LO program, so that’s why I want to test a LO program as well.

Cheers,

Olivier

PS: as a short fix for your problem, it should work if you include the branching ratio in your param_card since then MadWdith is not
going to be call.

Hi Olivier

I've tried running t t~ on LO and it still crashes with the following error.

Ok,

So this is indeed a problem of the LO handling of your specific cluster and does not have anything to do with MadSpin.

I guess that the problem is that the combine_events step needs a central disk that you do not have.
I will look how to solve that.
