US ATLAS HL-LHC computing discussion

[Meifeng Lin <meifeng AT caa.columbia.edu>]

Dear All,

Happy New Year!

Let's start the new year with another Fast Simulation WG meeting at 11am ET/5pm on Friday, January 4. 

There are a number of topics to discuss:

1. FastCaloSim CUDA port progress

  Zhihua has some success in getting the CUDA code to work with event loop parallelization. He will present the current status, and what needs to be done next. 

2. FastCaloSim reproducibility issue

  I had a meeting with some BNL ATLAS colleagues just before Christmas, and there were some questions about how we can better verify that the GPU and CPU versions indeed get the same results. It would be great if we can have some ATLAS FastCaloSim experts shed some insights on how we can handle this. 

3. FastCaloSim plan for the new CCE project
