# By default, GraphicsMagick is compiled with support for OpenMP (http://www.openmp.org/) if the compilation 
# environment supports it. OpenMP automatically parallizes loops across concurrent threads based on instructions 
# in pragmas. OpenMP was introduced in GCC 4.2. OpenMP is a well-established standard and was implemented in
# some other compilers in the late '90s, long before its appearance in GCC. OpenMP adds additional build and linkage 
# requirements.
# By default, GraphicsMagick enables as many threads as there are CPU cores (or CPU threads). According to the OpenMP
# standard, the OMP_NUM_THREADS environment variable specifies how many threads should be used and GraphicsMagick 
# also honors this request. In order to obtain the best single-user performance, set OMP_NUM_THREADS equal to the 
# number of available CPU cores. On a server with many cores and many programs running at once, there may be benefit 
# to setting OMP_NUM_THREADS to a much smaller value than the number of cores, and sometimes values as low as two 
# (or even one, to disable threading) will offer the best overall system performance. Tuning a large system with OpenMP
# programs running in parallel (competing for resources) is a complex topic and some research and experimentation may
# be required in order to find the best parameters.
