Using UNIX pipes - E+ in zeppy

Here we try to run E+ thru zeppy

Lets start by using eppy to do this (make sure you have eppy installed before you do this.)

Note: You can find this jupyter notebook at docs/tutorial_docs/eplus_zeppy.ipynb

[1]:

# setting the path name so that the tutorial works from this directory
# if you install zeppy with `pip install zeppy` you will not need to do this
import sys
# pathnameto_zeppy = 'c:/eppy'
pathnameto_zeppy = '../../'
sys.path.append(pathnameto_zeppy)

[2]:

import os
import eppy
from zeppy import ppipes
wfile = "/Applications/EnergyPlus-9-1-0/WeatherData/USA_CO_Golden-NREL.724666_TMY3.epw"

[3]:

fnames = [
    # "./eplus_files/Minimal.idf",
        "../../eplus_files/UnitHeaterGasElec.idf",
        "../../eplus_files/ZoneWSHP_wDOAS.idf",
        "../../eplus_files/ZoneWSHP_wDOAS_1.idf",
        ]
wfile = "/Applications/EnergyPlus-9-1-0/WeatherData/USA_CO_Golden-NREL.724666_TMY3.epw"
idfs = [eppy.openidf(fname, epw=wfile) for fname in fnames]

Let us write a couple of helper functions

[4]:

# the subsequent code will import these from ppipes.py
def idf_multirun(idf_kwargs):
    import eppy
    # for some reason idf.run() does not work
    # so I am using runIDFs to run one idf at a time
    idf = idf_kwargs['args']
    options = idf_kwargs['kwargs']
    eppy.runner.run_functions.runIDFs( [(idf, options)] )


def make_options(idf):
    idfversion = idf.idfobjects['version'][0].Version_Identifier.split('.')
    idfversion.extend([0] * (3 - len(idfversion)))
    idfversionstr = '-'.join([str(item) for item in idfversion])
    fname = idf.idfname
    options = {
        'ep_version':idfversionstr,
        'output_prefix':os.path.basename(fname).split()[0],
        'output_suffix':'C',
        'output_directory':os.path.dirname(fname),
        }
    return options

Now let us run the E+ files

[5]:

waitlist = [[{'args':idf, 'kwargs':make_options(idf)}] for idf in idfs]
func = ppipes.idf_multirun
result = ppipes.ipc_parallelpipe(func, waitlist, nworkers=None, verbose=True)
print(result)

Ha! all three files run.

The results are None, since we did not write code to exract and return any outputs from the E+ outputs

Let us try running on a single worker and see how long it takes:

EnergyPlus Completed Successfully.

OK. Took a bit longer running on just one worker

Multi core machines

  • some superficial testing has shown that on a multicore machine, each run is on a different core.

  • you can force the number of cores running by setting a value for nworkers

  • if you have more runs than cores. Say you have 4 cores and 50 runs, you can set nworker=4. The runs would be spread evenly on all the cores. About 12 or 13 runs on each core. Each core will execute the runs sequentially.

  • If you have 4 cores and assign 10 workers, it will still run. We have not checked ot see how it does it.
