When using HPC cluster, compute node hosting jupyternotebook mounts the tar file through ratarmount, but the dask worker nodes on other compute node does not.
Hi @andersy005 , @kmpaul
https://github.com/tinaok/xtar/blob/master/notebooks/tar-netcdf-HPCrealdata.ipynb
I was trying with NFS disk space on our HPC system.
ratarmount installed in my conda environment but can not access; may be I missunderstanding something?
As you can see, I installed libfuse in the same conda environment.
hello @kmpaul @andersy005
I was wondering if it would be possible to have dummy netcdf test data, like the one used on Pangeo-data/benchmarking;
This way we can bench what is the best tar, and netcdf chunked format to be stored at the mpi computation on oceanophysics or atmospheric computation; to perform Pangeo post-analysis computation later on.
I just put together a simple notebook demonstrating how to mount the tar archive via ratarmount. I then ran some smoke tests to see what the performance looks like:
Here's a rendered version of the notebook: https://nbviewer.jupyter.org/github/NCAR/xtar/blob/master/notebooks/tar-netcdf.ipynb. I included dask's performance report in the notebook itself.
