These lectures will be watched/rewatched for ages. Thanks to Prof. Marzari for giving us his own interpretations of this topic and expnations of the intemaditating and dare I say abstract equations. Will be looking forward to more such lectures (never ever in my life the phrase: 'will be looking forward' meant this much).

How to extract all the structure from ICSD and COD database and screen based on specific criteria? Also, is there any other option to mine the data from ICSD without paying?

Can you not submit multiple workfunctions (same function but different inputs/outputs) at a time to the Daemon then? For this you have to use Workchains?
@sphogliadelle
@sphogliadelle 4 жыл бұрын
Correct, process functions (i.e. calcfunctions and workfunctions) cannot be submitted to the daemon. They can only be run and that means they are run "blockingly", which means the interpreter cannot move on to the next one until the current one has fully finished. The difference with WorkChains is indeed, that when you submit them to the daemon, the daemon can run multiple at a time. When one workchain is waiting for a calculation to finish (that it launched), the daemon can in the meantime work on any other workchains that it is managing.

Hi, I have been trying to replicate this calculation however I get an error that "NameError: name 'Workchain' is not defined". Are there any formal definitions you made that are not in the video or any other lib you may have imported but are not in the video. Thank

You can go to www.materialscloud.org/work/tools/seekpath , but the short URL that Giovanni says should also still work.
