Notes on Singularity

November 14, 2017

• no singularity module on ifarm1101 (CentOS6)

  ifarm1101:marki:marki> module load singularity
  ModuleCmd_Load.c(204):ERROR:105: Unable to locate a modulefile for 'singularity'
  

• user-space singularity build did not work:

  > singularity shell /scratch/marki/centos7_farm.img
  ERROR  : Failed invoking the NEWUSER namespace runtime: Invalid argument
  ABORT  : Retval = 255
  

  Seems to need to be installed by root. See https://github.com/singularityware/singularity/issues/415

• singularity is a standard package under fedora 26, RHEL7
