Installing own tools

Installing own tools#

Adding some packages to existing modules#

Tykky#

  • The easiest way to create a custom installation is with Tykky

  • Tykky has 3 options, new installation based on:

    • conda .yml file

    • pip requirement file

    • Existing Docker image

  • CSC Docs: Tykky

  • LUMI Docs: container-wrapper is the same as Tykky

Do not use “normal” conda installations

  • “Normal” conda installations create a lot of files - up to hundreds of thousands

  • Supercomputers do not like too many files

  • Use Tykky to create containerized conda installation

Installation exercise#

Tykky installation based on existing Docker image#

  • We will install lastools based on pydo’s lastools Docker image.

  • We use the projappl disk, which is the best place for software installations.

  • Lastools is already available on Puhti, also as a newer Linux-native installation.

  • During the course we will use an interactive job for doing the installation, because we will have 50 users doing it at the same time, which stresses the shared file system. Usually installations are done on a login node.

Change the default project and username

  • project_20xxxxx is an example project name, replace with your own CSC project name.

  • cscusername is an example username, replace with your username.

  • Open Puhti web interface and log in

  • Open Compute node shell (outside of the course, also Login node shell could be used)

    • Reservation: geocomputing_thu (only during the course)

    • Project: project_20xxxxx

    • Partition: small

    • Number of CPU cores: 1

    • Memory (GB): 4

    • Local disk (GB): 4

    • Time: 00:30:00

Make Tykky tools available

module load tykky

Create a new directory for the installation and make the folder above it your working directory

mkdir -p /projappl/project_20xxxxx/students/cscusername/lastools
cd /projappl/project_20xxxxx/students/cscusername

Create the new installation

wrap-container -w /opt/LAStools docker://pydo/lastools:latest --prefix lastools

  • -w /opt/LAStools - where the tools are located inside the container, it should be accessible

  • docker//:pydo/lastools:latest - the existing Docker image

  • --prefix lastools - location of the new installation

Add the location of your new installation to your PATH. Note that Tykky prints out the correct command for you.

export PATH="/projappl/project_20xxxxx/students/cscusername/lastools/bin:$PATH"

Test your new installation.

lasinfo -version
lasinfo -i /appl/data/geo/mml/laserkeilaus/2008_latest/2018/W444/1/W4444G4.laz

PATH setting

PATH defines where the system looks for tools. Changes to PATH, like those above, are in effect while the Puhti session is alive. PATH (or PYTHONPATH) has to be set again in each session, so it is good to add it to your batch job file.
