As mentioned in the EnergyPlus 9.3.0 update log, gpus can be used to accelerate computation

Hi Chris, me and another user are having a problem while following your Honeybee YouTube tutorials which I think is related to the EP v9.0 and EP v9.3 issue.
-Honeybee seems to be recognising only Energyplus v9.0 even if EP v9.3 is installed. The output from the Honeybee_Honeybee(Honeybee) component says that it found EP v9.0 even if EPv9.3 is installed.
-Therefore it writes only v9.0 IDF files, which Energyplus v9.3 does not work with.

My work around was to download EP v9.0 and run the simulation manually in Energyplus, and then reimport the result into grasshopper.
Here is the original thread.

Energy Plus Error

[EP workaround] I’m having the exact same problem. As far as my (limited) understanding goes, this is caused by Honeybee writing EnergyPlus files in v9.0 whereas the EnergyPlus engine you would have is v9.3. Energyplus is not able to process this older file. This seems like a bug in the software. Whether the above analysis is true or not, I have found a workaround. Basically it involves manually using EP v9.0 to run the simulation, outside grasshopper, and then getting Grasshopper to read that…

Thanks a lot for these brilliant tools and tutorials!
