Program stops without explicit error message #21

Open myndtrust opened 5 years ago

myndtrust commented 5 years ago

I am running the program without any changes and it keeps exiting without completing. At times the error file is empty others I get a weather file vs IDF error. Is there a minimum number of time-steps? Are there any changes that we need to make to the IDF files or other settings?

Note: this is on Ubuntu 18.04.

What did happen when the execution was stopped ? How many episodes have been completed ? (looks like you have done at least 20 episodes ?)

eplusout.err file usually contains many warning messages as follows:

I have ran this on a couple machines, including Ubuntu 16.04 and 18.04. Most runs have quit at the start of the episode001, when num-timesteps is below the 10e9. There seems to be a correlation with num-timesteps and the max episode that can be successfully run. Can you confirm?

The most episodes I was able to run was 5099 with num-timestep set to 10e9 (ran out of storage before program errored out).

Have you had a successful run with anything else than 10e9 num-timesteps?
