[Kathryn M. <ka...@ll...>]

Hi everyone,

We're pleased to announce a new release of the Scalable Checkpoint/Restart
Library, version 1.1.8. Go to: https://github.com/hpc/scr/releases to
download.

What's new since v1.1.7:
- Added support for Cray XT systems with aprun
- Added Fortran interface, and simplified use for C++ applications
- Added SCR index file in prefix directory to track history of datasets,
dropped current and old symlinks
- Added scr_index command to manage datasets
- Simplified single-node use
- SCR metadata and redundancy files moved to hidden .scr subdirectories
- Improved scavenge behavior to avoid wasting time scavenging non-repairable
datasets
- Added new group, store, and redundancy descriptors to express more storage
and failure topologies
- Improved scalability of SCR summary metadata file via new hierarchical
rank2file
- Numerous bug fixes

Hope you enjoy it, and let us know if you have questions or encounter
problems. The discussion mailing list is here:
https://computation.llnl.gov/project/scr/contact.php
or if you're already signed up to the list, just email

Thanks!
Kathryn - and the whole SCR team!

I realized that the link I provided won't work with the exclamation point on the end. Try this one: http://www.rce-cast.com/Podcast/rce-84-scalable-checkpoint-restart.html

[Kathryn M. <ka...@ll...>]

Hi all,

Adam Moody and I were recently interviewed in an RCE podcast: http://www.rce-cast.com/Podcast/rce-84-scalable-checkpoint-restart.html!  

Have a listen to hear details about how checkpointing and SCR work on HPC systems and how we hope to make SCR squirrel-proof :-)

Kathryn
