The Snowmass process in the US was paused for the pandemic and now it restarted. Discussing with O. Gutsche, D. Elvira and W. Bhimji, it would be important to submit an input from the WLCG perspective, same as we did for the ESPP process in Europe. The input could be a short document with links to existing ones. The main messages would include: 

* a general vision and strategy statement from WLCG for the next decade, what are the main challenges and how it sees the infrastructure evolving  

* the importance of collaborating across HEP experiments on a shared computing infrastructure and the advantage of sharing the core services with other sciences (for example astronomy/astroparticle) 

* State the important role of Open Science Grid in supporting the infrastructure in the US and collaborating with other international grid initiatives (such as EGI) in providing core services to WLCG.

* State the important role of investments in R&D to support the future HEP computing needs. Mention IRIS-HEP as an example    

The input would target mostly the Storage and Processing Resource Access topical group (TG) but could expand broader that that in the Computing Frontier (opinions on that?). The deadline is mid-March 2022 but the title and abstract need to be available by the end of January.

If we agree we should do this, we should form a small editorial team and produce an abstract (first) and the full document in the next 30 days. The document needs to be agreed by the OB and the CB
