The Backend¶

Memory Management¶

For some calculations it might be a smart idea to process the requested angles in chunks of a certain size. First, because it might result in fewer cache misses and second one might be running out of RAM to run the calculations. To this end, you might set the EADF_LOWMEM environment variable and use it together with the blockSize property and the optimizeBlockSize function.

Datatypes¶

We support single and double precision calculations. This can be set with the EADF_DTYPE environment variable. Most of the time single precision allows approximately twice the computation speed. This is reflected in the dtype environment variable.

Environment Variables¶

EADF_LOWMEM: yay or nay?

EADF_DTYPE: single or double?
