Check-Out from Gitlab.com

For the Cray XC40 Hazelhen cluster, direct access to gitlab.com is blocked. Instead, a ssh-tunnel has to be used. The required steps are the following

  1. Login to a Server/Computer with direct access to the Hazelhen cluster, e.g.
    • iagpc151
    • IP-Address from the range of the IAG
    • Certain IP-Addresses within Edurom of University of Stuttgart
  2. Use a SSH-Tunnel to connect to the Cluster

  • Version 1

    Login with SSH-tunnel and clone repository from [email protected]:piclas/piclas.git

        ssh -R 7777:gitlab.com:22 [email protected]
        git clone ssh://git@localhost:7777/piclas/piclas.git

  • Version 2

    Login with SSH-tunnel and clone repository from git://github.com/piclas/piclas.git

        ssh -R 7777:gitlab.com:9418 [email protected]
        git clone git://localhost:7777/piclas/piclas.git

Building with ccmake on hazelhen

For building on the hazelhen-cluster, the following steps are needed:

  • include in .bashrc or .profile:

      module unload PrgEnv-cray
  module load PrgEnv-intel
  module load cray-hdf5-parallel
  module load tools/cmake

  • Profiling with Craypad

    • Compile PICLas with '''
      module load perftools-base && module load perftools-lite && export CRAYPAT_LITE=event_profile '''
    • Run PICLas with normal submit script
    • Program has to finish normally! Enough time during execution. Note, that the profiled version is slower, hence, the testqueue is maybe to short.
    • Visualize the *.app2 files
