I don't really understand why the CI could fail in GPU. @pramodk Ideas? |

There was a problem hiding this comment.
What is often do is to enable a "double sigterm", to really cut things
How long is this checkpoint can be?
sorry for delay - this issue is being investigated. You can ignore this error. |

Can you rebase this @ferdonline? |

Motivation
As a follow up to #252, we want CoreNeuron to be able to create checkpoints right before an allocation expires.
Since most job schedulers send a SIGTERM before sigkill, we implement a handler for such signal. It may, however, be needed to tune the time to sending this signal, since long simulations may take a bit of time to write everything out.
Implementation
Checkpoints are created in a folder
_corenrn_ckptinside the output root only if a minimum amount of time elapsed.This directory is checked for existence on startup if no
--restoreis provided.
