The OMP_TOOL environment variable sets the tool-var ICV, which controls whether an OpenMP runtime will try to register a first party tool.
The value of this environment variable must be one of the following:
enabled | disabled
If OMP_TOOL is set to any value other than enabled or disabled, the behavior is unspecified. If OMP_TOOL is not defined, the default value for tool-var is enabled.
% setenv OMP_TOOL enabled
