marcoabreu opened a new issue #8726: CI: Remove building from Unit Test-Jobs
URL: https://github.com/apache/incubator-mxnet/issues/8726
 
 
   At the moment the compile-stages are kept pretty generic while language-specific builds are being executed during the Unit Test-Stage. In order to improve future scalability these two steps should be two separate jobs. This can be done in two ways:
   
   1. Add an second build-stage which executes language-specific actions. Disadvantage: This increases the total duration as all jobs have to finish until the next stage can be started.
   2. Nested jobs: If a Unit Test requires previous actions, split it into two jobs which are getting executed in sequence. This will allow in future to execute CPU-heavy tasks on a CPU-instance and GPU-tests on a GPU-instance.
   
   Execution in separate jobs allows reusing the created artifacts if multiple jobs exist for the same language.
   For examples consider looking in the Jenkinsfile at R: CPU/GPU, Scala: CPU and Perl: CPU/GPU (perl-package.test.sh).
