On Solaris your system adminstrator can increase the amount of available privileged memory by editing the /etc/project file on the nodes. For more information see Solaris “project” man page. shell% man project As an example of increasing the privileged memory first determine the amount available (example of typical value is 978MB): shell% prctl -n project.max-device-locked-memory -i project default NAME PRIVILEGE VALUE FLAG ACTION RECIPIENT project.max-device-locked-memory privileged 978MB – deny – system 16.0EB max deny – To increase the amount of privileged memory edit /etc/project file: Default /etc/project file. system:0:::: user.root:1:::: noproject:2:::: default:
