Conrad tested the demo from CERN and it worked well. So, now I can focus on the next step of the project.
Conrad also sent me a link to more root data files so as the next step I will test the demo with those new root data files. The first demo only uses a single rootlet and the reason for this is mainly the way how the Clarens client is written. Each analysis request is processed synchronously and hence the client send requests one by one to the server for each root data file to be analyzed.
As the next step of the project, I am planning to run the client in with multiple processes and allow it to create multiple rootlets so that the analysis can be performed simultaneously utilizing the full cpu power. Hope to get the results soon.
