The OpenQuake engine version 2.1 ("Hugo Benioff") has been released

[Michele Simionato]

This release has focused on memory optimizations, with the goal of making the engine able to tackle extremely large calculations. We were able to successfully run event based risk calculations two orders of magnitudes larger than before and classical hazard calculations one order of magnitude larger.

As usual, new ground motion prediction equations entered in hazardlib, various improvements were made to the Web UI and several bugs were fixed. Over two hundred pull requests were closed in the GEM repositories.

This version of the engine is dedicated to the american seismologist Hugo Benioff.

You can find the release notes here:

https://github.com/gem/oq-engine/blob/engine-2.1/doc/whats-new.md

You can install on all supported platforms (Linux and Windows) by following the

instructions given here:

https://github.com/gem/oq-engine/blob/engine-2.1/README.md

You can download the OpenQuake engine manual from here:

http://www.globalquakemodel.org/openquake/support/documentation/engine/

As usual, the engine is not able to read or export computations

performed with previous releases, so if you have results you want to

keep, please export them before upgrading, otherwise repeat the

computation.

That's all, please let us know if you have any trouble with the upgrade.

Hello OQ Developers,

Although I post some message here before, still I have some problems importing Master from Github into my current version of OQ 2.0.1 that I would appreciate if you help me to figure it out. I read the Manual guide and followed the instruction on “Installing the OpenQuake Engine for development” and succeed to implement the development environment into my current version of OQ, but it doesn’t work and freeze at the first step of the analysis. The new engine and library are placed in a folder named “src” and according to the Manual, it is supposed to run the development environment from that folder which has the new updates. Also, it is important to mention that even after closing the development environment and switch to the previous version, none of my previous codes run at all and I couldn’t use the OQ-engine anymore. Since I really need to use the new update, I would be grateful if you help me to solve my issue.

Also, I should mention that I just upgraded the OQ version 2.1, but I need to know the process of using the development environment in case of new update pops up in future.

Thank you in advance for your consideration.

Regards,

Vahid

May I ask why you want to install the development version? The only concrete case when it is needed is if you want to develop new GSIMs or new calculators. Is that your case? If so, be prepared to a significant learning curve, both on the technological side and on the scientific side, which is out of the scope of the help that we can give on the mailing list.

Thank you for the heads up. Since I’m doing my research project in this area, I need to develop some codes by myself and test those in the developer environment. Although I have the experience to work with Github, but installing the development feature in my current version of OQ has been turned to a big issue for me so far. So, I would appreciate if you help me to sort it out. 

Best,

Vahid

As I was saying in my previous email, developing with the OpenQuake engine is nontrivial, installation issues are just the tip of the iceberg. This is not something we can teach on the mailing list, you would need something like an internship at GEM. This is possible (we regularily have Ph.D. students or researchers coming to GEM for short periods of time) but requires an agreement between your organization and GEM. So, please speak with your higher ups and have them to contact us.
