Computing web : KCMS Computing project


This is the main page of the KCMS computing project.

KCMS Computing workgroup activities:

  • KCMS computing resource management, general planning
  • Share know-hows for computing Tier site operation
  • Support full analysis workflow for KCMS users, provide general user guides
  • Feedback to tier site administartors

From the experiences in LHC-CMS Run I, a powerful computing resource is proven to be the key for the successful physics analysis. During the LS1 period, a task force for the KCMS computing is organised to support efficient computing for the data analysis. In the KCMS, there are 1 official Tier2 site (KNU) and 2 official Tier3 sites (UOS and KISTI). There can be institutional local resources linked with these tier sites.

KCMS computing meeting is held biweekly (adjustable depending on schedules), chaired by Prof. Intae Yu.
Computing managers are welcomed to present their status and give ideas to improve KCMS computing environment. Users in KCMS are also welcomed to share experiences in the analysis.
Discussion items can be found in KCMS computing Task Force meeting.

General guide to use KCMS computing resources

You have to be registered as a KCMS member.
To use CMS grid resources, you must register as a CMS member and create your grid certificate. Full registration procedure and getting grid certificate can be easily done when you visit CERN, but basically you can follow the procedures remotely in Korea. (It is best to visit CERN for your registration. Remote registration is slow and problematic in many cases.)

We recommend you to register to the official tier sites in Korea. There are three official tier sites, you can choose one depending on your location and group policy. Also it is free to register to all sites. Having account in tier site allows you to use local analysis farms, do easy-access of data files, store your large crab output files and share with your collaborators. You can also pull the dataset you are interested in to the site by PhEDEx? request (needs approval by site admin).

Send registration form to site administrators with your information. Some site admins may ask you to be verified by your group leader.
Check the followings for more information.
