# Madgraph4gpu dev meeting Tue 25.04.2023


Present: SR, AV, JT, OM, NN, TC, ZW, CV

Excused: SH


## Discussion on licensing


AV presents a proposal for copyright and licensing.

General agreement, go ahead and merge it.

We can rediscuss this later on if needed.

Let's focus on technical stuff and development.

TC: especially let's focus on completing functionality for the release, rather than on further speed improvements


OM: technically best is to create two repos under mg5amcnlo,

and have the plugins there for sycl and cudacpp


## Short round table


ZW: poster at CHEP was upgraded to a talk!


OM: new phase space integrator based on machine learning

Very good results for the moment, factor 5-10 better in unweighting efficiency 

(here 5-10 for W->du, but also same range for other processes).

Here GPUs will be very useful for training.


TC: ntr


CV: ntr


NN: ntr


JT: containers for both cudacpp and sycl are ready!

(code is here 

Can download and build everything both on cudacpp and sycl.

Using the llvm of sycl, not oneapi for licensing reasons.

AV: great! maybe NN can cross check that you get the same results,

since this may be a different sycl version


AV: nta - will merge the PR after the meeting!


SR: in contact with nvidia to include our code as a benchmark in their suite


## AOB


SR: next meeting? agreement on May 2nd.


There are minutes attached to this event. Show them.
