Introduction
NGI Status
NGI | Status |
---|---|
NGI Ibergrid | IBERGRID is already using CVMFS stratum 0 deployed at RAL as a service |
NGI_ZA | We were planning to deploy a stratum 0 in South Africa for VO sagrid applications, as well as those in use in other sub-Saharan countries. |
NGI HR | We are running CVMFS for our regional VO. |
NGI FI | we are one of the non-WLCG organizations running cvmfs. |
OSG | We recently implemented a CVMFS based service for the OSG. Our intended use case is for our virtual organizations and software
group to distribute their content by this mechanism. Our design is quite simple, we allow a very few people write access and everyone read access. We are actively adding resources with access enabled, wide adoption being the goal. |
VO status
- (1) is your community already familiar with CVMFS and is CVMFS already used in some form to support production activities?
- (2) are you interested in trying CVMFS?

VLEMED VO | (1) used in some form to support production activities?
we were not until this email, but we asked around. The Dutch NGI is taking action already for non HEP users. we look forward to their findings. (2) yes. |
johan montagnat | (1) No, we were not aware of this tool before.
(2) There is a clear need for easily deploying software packages grid-wise in the LS community. The existing solution of populating VO software space per site is often considered tedious, and leading to incoherent state when software cannot be installed on some sites due to installation job issues. So an alternative and global scale solution would be welcome. We would need to know a bit more on CVMFS though. From the slides shown, it is not clear how the software registered on the central CVMFS root directory is accessible from the sites / worker nodes in particular. (Is the CVMFS root mounted from all worker nodes? What is the performance impact of accessing to this remote software?). |
