[joss-review] memory requirement of example run

[zonca]

the first step of the analysis requires about 20 GB of RAM, it would be useful to specify it in the docs, I ran with 15 GB and the process was killed (probably for out of memory)

I'll also estimate memory requirement for the second step and add it here.

I've updated the "Test Dataset" docs under usage.rst with RAM requirements (b9af6b5). When I ran the test dataset on a slurm system, I see the matrix construction step required ~17 GB of RAM according to the MaxRSS column in the slurm database and the power spectrum analysis required ~12 GB of RAM. The RAM requirement for the matrix construction being ~17 GB is probably why your job was killed with 15 GB of RAM but succeeded with 20 GB.

it seems like the docs website is not automatically updating:
https://bayeseor.readthedocs.io/en/latest/usage.html#running-the-power-spectrum-analysis

as you estimated the power spectrum requirement for power spectrum analysis, I think it would be a good idea to add that number in.
Do you also know how much GPU memory is needed?

Ah, yes. I had to manually rebuild the docs (I haven't automated the docs building yet). The documentation should be updated now.

Regarding GPU memory, I believe the routing we are using in MAGMA is capable of partial i/o so it should be capable of running on a wide range of hardware. I can try re-running the test data analysis and using e.g. nvidia-smi to try and get some information on GPU memory usage if necessary.
