hi, my testcode is running properly on 5 threads thanks for the help

```python import xarray as xr import os import numpy import sys import dask from multiprocessing.pool import ThreadPool

dask-worker = --nthreads 1

with dask.config.set(schedular='threads', pool=ThreadPool(5)): dset = xr.open_mfdataset("/data/Environmental_Data/Sea_Surface_Height//.nc", engine='netcdf4', concat_dim='time', chunks={"latitude":180,"longitude":360}) dset1 = dset["adt"]-dset["sla"] dset1.to_dataset(name = 'ssh_mean') dset["ssh_mean"] = dset1 dset = dset.drop("crs") dset = dset.drop("lat_bnds") dset = dset.drop("lon_bnds") dset = dset.drop("xarray_dataarray_variable") dset = dset.drop("nv") dset_all_over_monthly_mean = dset.groupby("time.month").mean(dim="time", skipna=True) dset_all_over_season1_mean = dset_all_over_monthly_mean.sel(month=[1,2,3]) dset_all_over_season1_mean.mean(dim="month",skipna=True) dset_all_over_season1_mean.to_netcdf("/data/Environmental_Data/dump/mean/all_over_season1_mean_ssh_copernicus_0.25deg_season1_data_mean.nc") ```
