Improved FAQ

Nuria Pérez-Zanónrequested to merge
develop-FAQ-SGW4 into master

Hi @aho

Given the issue @acarreri found when running her code in Nord3, I have extended a FAQ in section 'Something goes wrong'.

The problem was that the variable was being requested in return_vars:

data <- Start(..., var = 'tos', ...,
              return_vars = list(tos = NULL), 
              retrieve = FALSE)

The local run of Compute() worked fine, but, when submitting to Nord3, the job stacked showing in the following line Chunk.1.err:

Rscript load_process_save_chunk.R --args $task_path 1 1 1 1 1 2 1 4
+ Rscript load_process_save_chunk.R --args /gpfs/scratch/bsc32/bsc32339/startR_hpc//STARTR_CHUNKING_5265358669///STARTR_CHUNKING_5265358669/computation/sdate_CHUNK_1/ensemble_CHUNK_1/var_CHUNK_1/dat_CHUNK_1/Chunk 1 1 1 1 1 2 1 4

I have thought that the best option is to write it down in the FAQ because:

  • It is very difficult to debug the problem (there is no info in the logs and we cannot reproduce the problem in the WS) and
  • by adding 'tos' in return_vars, the data is being loaded in the attributes, so, it is not a very good practice

Could you both take a look at the new text and let me know your opinion?

Cheers,

Núria
