CosmicEmu

[njlai]

I am getting a "failed to download CosmicEmu code" error. I am uncertain if this is something that I needed to install as I did not see it mentioned on the installation page. In the physics documentation it simply says that it will be downloaded so I must be doing something wrong... Thanks for the help.

Can you explain what you're trying to do? (Or paste your parameter file here.) The CosmicEmu code is the default option for computing nonlinear power spectra - if you don't need that we can simply disable that calculation.

[njlai]

Ah I see. I really only care about star formation. How would I go about disabling that chunk. Just set the powerSpectrumNonlinear to one of the other options? (or null)

[abensonca]

You can add

  <powerSpectrumNonlinear value="linear"/>

to your parameter file - this will just use the linear power spectrum for the nonlinear calculation (which is obviously incorrect, but is fast,).

Also, most likely you have:

<task value="powerSpectra"/>

in your parameter file. If you don't care about the power spectrum you could just remove this completely.

[njlai]

Are there any example/tutorial files you could reference that implement the massFunctionStellarBaldry2012GAMA just so I could see a working example. Thanks.

That solved the previous error but this is the one I am getting now:

I checked and the file "gravitationalLensingConvergenceTakahashi2011.hdf5" does exist and there are values in the convergenceVariance chunk of the HDF. Right above the "fatal error" line it also says :

HDF5-DIAG: Error detected in HDF5 (1.8.20) thread 0:
#000: H5T.c line 1754 in H5Tequal(): not a datatype
major: Invalid arguments to routine
minor: Inappropriate type

[abensonca]

Try removing the gravitationalLensingConvergenceTakahashi2011.hdf5 file and running again. It may have been left in a broken state by the previous failure. It will be recreated as needed.

[njlai]

Still getting it, I also did a full reinstall. At run-time, an hdf5.lock file is also being created. Is this intended or could this be why it is unable to access the data?

[abensonca]

I'll have to look into this more carefully. For now you could add:

<gravitationalLensing value="null"/>

to disable gravitational lensing. It won't matter for these very low redshifts anyway.

[njlai]

It is working now. Thanks so much for working me through this, I really appreciate it. Have a good rest of your day 😄

[abensonca]

I've made some updates to the code that are now tested and merged in and should resolve the errors described above related to gravitational lensing.
