If you intend to manipulate a very large model, it is possible to
increase the memory used by GNA by setting the JAVA_ARGS
variable. For instance, value -Xms256M -Xmx1024M
allows GNA to use a memory of 256 Mb up to 1024 Mb.
On Windows, open the System
properties, select the
Advanced tab, and click on
in order to define a new
variable with the name JAVA_ARGS
.
On Linux or MacOS, use one of the following command, depending on your shell:
setenv JAVA_ARGS "-Xms256M -Xmx1024M"
export JAVA_ARGS "-Xms256M -Xmx1024M"
