Computers for building FESA/DevAcc Software

At GSI the following computers can be used to design, code, compile and link FESA classes and equipment:
  • asl740, asl741, asl742, asl743, asl744 ( CentOS (acc7), 64-bit architecture, FESA3 4.0.0 to 7.3.0 )
  • asl751 to asl755 (Rocky9 - acc9 / yocto, 64-bit architecture, FESA3 7.5.0 and later)

Computers for testing FESA/DevAcc Software

Note that FESA software build on the acc7 cluster can be tested directly on that cluster, if no timing-network is required.

The following front end computers may be used for testing purposes. Be aware: This list might be outdated! (Last complete update: 25/09/2023).

To make use of one of these front end computers, follow these steps:
  • Ask other users registered for that system for access, if there are any
  • Make sure no other FESA/Devacc binary is running on the chosen computer (If so, check who is running it)
  • register yourself in this list with your full name. If you are an external, as well provide a mail address.
  • If the usage is temporary, unregister yourself when you are done

Other FECs

FEC Configuration

All FEC's share the same basic structure of an Initrd Based Linux System and are located in the accelerator network (connect via '.acc.gsi.de' suffix)

  • Information about the file system for FEC's: FEC file system.
  • For productive FECs, here some info on how to use hostnames / GSI nomenclatures as FEC names: https://www-acc.gsi.de/wiki/FESA/FrontEnds
    • For FEC configuration of a FESA3 deploy-unit this means that the FEC folder still has to be named like the original hostname of the FEC (unexpected!)
    • Logging in to the FEC also requires the original hostname (unexpected!)
    • Retrieving log messages from the booting FEC also requires the original hostname (unexpected!)
    • If nomenclatures for FEC names are used in capital letters, they cannot be distinguished any more from common device names at first sight

RAM Disk Configuration

  • Information about boot-configuration: Start on EmbeddedSystems.
  • This Wiki page provides information on how to read/set the PXE links for the Linux image and RAM disk of a FEC.
