Description

The Compact Muon Solenoid (CMS) experiment is a large general-purpose particle physics detectors built on the proton-proton Large Hadron Collider (LHC) at CERN in Switzerland.

Acceptable Use Policy

Text This Acceptable Use Policy applies to all members of [VoName] Virtual Organisation,
hereafter referred to as the [VO], with reference to use of the EGI Infrastructure.

Other requirements

Note: CMS usually sends 8-core pilots, values for 'Multi Core' refer to that. Single-core pilots are discouraged. Jobs require an address space larger than the memory size specified above. Sites should allow processes to use at least 6GB of virtual address space more per core than memory to accommodate the large amount of shared libraries used by jobs. (For a typical 8-core pilot that would translate into a VZSIZE limit of at least 64GB.) Cloud resources should provision 8-core VMs to match standard 8-core pilots. Input I/O requirement is an average 2.5 MB/s per thread from MSS. All jobs need to have outbound connectivity. Sites must not use pool accounts for the FQAN cms:/cms/Role=lcgadmin . For any other CMS job, sites need to use pool accounts so that at any time every grid credential is mapped to an independent local account. National VOMS groups: In CMS national VOMS groups, e.g. /cms/becms or /cms/dcms, are used. Those proxies must be "supported" at all sites in the following way: - should be treated like /cms (base group), in case no special treated is wanted by the site - proxies with such national groups must be able to write to /store/user/temp (the PFN associated to this LFN)
