Choose c1a (not ecgate) upon login to access the supercomputer facility (HPCE)


Copy the following directory and files to your home directory on HPCE:

flex_extract_ecgate_V4

(this directory you can find under Sabine's or Nina's user sbc/ or sb9/)


List of files:

flex_ecmwf_91_finegrid_*

extract_ecmwf_ftpbase

seq_extract.V4*

seq_control.V4*

submit*


1. Edit the times in the file: seq_control.V4*

./seq_extract.V4 1990 1990 06 06 29 29 1

This extract the files from 1990 06 29 to 1990 06 29 - for 1 day!


2. In file flex_ecmwf_91_finegrid_* modify the following parameters:

M_GRID 20 (resolution 0.2 deg, for resolution of e.g. 10 deg use 1000)

M_LEFT -3600 (36 W)

M_LOWER 4000 (40 N)

M_UPPER 7600 (76 N)

M_RIGHT 3600 (36 E)

M_FORMAT GRIB2 (GRIB1 or GRIB2)

DESTINATION nina (or another MS association set up on the web interface, e.g flexpart)

ECFSDIR ectmp:/${USER}/GRIM/ (directory name)

SOURCECODE /home/ms/no/sb9/flex_extract_ecgate_V4 (your username)


Notice:

M_GRID/90 must be a whole number

M_LOWER/M_GRID must be a whole number, same with the three other coordinates

(M_UPPER-M_LOWER) / M_GRID must equal a whole number

(M_LEFT-M_RIGHT) / M_GRID must equal a whole number


3. Change all paths to refer to your own user

grep sb9 *

to list all files containing the path with user sb9 which need to be changed.


4. Copy the template file flex_ecmwf_91_finegrid_* to extract_ecmwf_ftpbase

cp flex_ecmwf_91_finegrid_* extract_ecmwf_ftpbase


5. Run the job:

./submit


6. Check your job:

llq to see your job in the queue

eoj <jobid> provides details on the performance of a running job. (also automatically provided at end of job)


7. Get your files:

The retrieved files are automatically transferred to your ecgate account (via ECTRANS) and then to NILU by ftp. (NB: cannot ftp directly from HPCE, but must go via ecgate).

If you can’t find your files in your defined NILU-directory, check the directory you specified in flex_ecmwf_91_finegrid_* (ECFSDIR) for where it is temporarily stored on the ECWMF system.

Then try ftp it over again using the ftp commands specified previously.
