The PI is responsible to closely follow the progress of the action, and especially to contact NEMO project manager if the delay on preview (or review) are longer than the 2 weeks expected.

Help

The action has to be detailed briefly in the 'Summary' section for later inclusion in other pages.
Edit the 'Summary' section as with an ordinary wiki page.

  • Italic formatting shows the default values or help.
  • Set specific TracLinks (development ticket and branch).

Out of this, the rest of the page can be edited on-line inside the form fields considering the following color code given hereafter.

Role / Color code

PI(S) Previewer(s) Reviewer(s)

Record your modifications for the section you have edited by clicking on the corresponding button at the end of the section with 'Save ...' button. Just above, the log record will be updated.

The informations inside the form fields and this wiki page itself are stored in 2 separate databases.
As a consequence, there is absolutely no risk to make any modification in the page itself as long as you don't rename the page or modify the source code of {{{#!TracForm ... }}} processors.

Digest

As the number of cores in NEMO increases parallel reading of single netcdf files (e.g. restarts, forcing, observations) is becoming increasingly slow.
This action will test the use of XIOS for reading these input files. This ticket will document development related to reading restart file only.

Dependencies XIOS development. Currently the number of NEMO CPUs which can be used when reading data via XIOS is limited to 3700

Abstract

This section should be completed before starting to develop the code, in order to find agreement on the method beforehand.

Error: Failed to load processor TracForm
No macro or processor named 'TracForm' found

Once the PI has completed this section, he should send a mail to the previewer(s) asking them to preview the work within two weeks.

Preview

Since the preview step must be completed before the PI starts the coding, the previewer(s) answers are expected to be completed within the two weeks after the PI has sent his request.
For each question, an iterative process should take place between PI and previewer(s) in order to reach a "YES" answer for each of the following questions.

Error: Failed to load processor TracForm
No macro or processor named 'TracForm' found

Once all "YES" have been reached, the PI can start the development into his development branch.

Tests

Once the development is done, the PI should complete this section below and ask the reviewers to start their review in the lower section.
