# 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!

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.
