Section

A custom amount of memory can be reserved for simulations by setting the environment variable FLUX_MEM before starting the Flux Simulator:

shell

(Linux/Unix)

Code Block
$ export FLUX_MEM="4G"

cmd

(Windows)

Code Block
 C:\>set FLUX_MEM="4G"

Section

While iterating all reads, the Flux uses heavy disk traffic. To speed up processing, provide a fast (i.e., in most instances a local) hard drive for the input data and the temporary file folder (TMP_DIR, either as a parameter or by setting the corresponding environment variable). The FLUX_MEM setting has an indirect influence on the disk traffic, because all loci that contain more reads than can be loaded with the provided memory limits are to be sorted on disk. Depending on your experiment size and the protocol, it is therefore recommended to provide some GB of memory to avoid additional disk access.
