Life Science Grid clusters¶
The current page provides information about the Life Science Grid (LSG) clusters and their locations, local support contact persons, and DNS addresses of User Interface (UI) and Storage Element (SE) machines.
Warning
The Life Science Grid infrastructure is scheduled to be decommissioned mid 2018. After the decommissioning the smaller LSG clusters within the UMC’s and other universities will cease to exist; the large central Grid clusters at NIKHEF and SURFsara will remain. More details about the decommissioning can be found here: https://userinfo.surfsara.nl/documentation/decommissioning-life-science-grid
About¶
The Life Science Grid is a compute and data processing infrastructure that is available for all Life Science researchers working in the Netherlands. The Life Science Grid consists of a series of computer clusters that can be used either as a local facility or as an integrated Grid environment. For both types of usage, you will need an account on a User Interface machine. Accounts on the user interface machines are managed via a central system at SURFsara, and can be arranged after verification by a local site support contact person. To arrange access, the most efficient way is to ask (one of) your local support contact(s) to send a request to our helpdesk for access to the local User Interface machine. Your local support person will need your name, e-mail address, telephone number and nationality, and will verify that you are employed at the relevant institution and an active researcher in one of the Life Science disciplines.

Security¶
The default permissions on the LSG clusters for /home, /home/nobackup and /scratch directories is:
read+write+execute for the user
read+execute for the group
read+execute for others
In general, where security is important, we advise you to verify and set the permissions to abide by your data access regulations, especially for temporary working directories under /scratch and /tmp. For example, you can do $ umask 0077 to keep all data invisible to other users or $ umask 0007 to keep it closed for everone outside the group. Another point of attention is cleaning up intermediate data before job exit.
