Hello,
I am an undergraduate student and I am learning ET for my project. I am having trouble running the helloworld simulation. Everything works out but when I do "show-output" I get this on my terminal:
Simulation name: helloworld Warning: job status is U Warning: job status is U Warning: Job is not running, cannot retreive exechost ================================================================================ The job's Formaline output is: ================================================================================ (file does not exist) ================================================================================ The job's stdout is: ================================================================================ Simulation name: helloworld Running simulation helloworld Preparing: Checking: /home/swarnim/simulations/helloworld/output-0000-active koszmikroid-X550LD Mon Mar 26 17:44:46 IST 2018 Environment: Starting: INFO (Cactus): Increasing logging level from 0 to 3 Mon Mar 26 17:44:47 IST 2018 Simfactory Done at date: 0

Please let me know what the problem is and how to sort it.
