This is the command primusrun that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
primusrun - run an application on a discrete NVIDIA video card
SYNOPSIS
primusrun command
DESCRIPTION
Primus implements low-overhead local-only client-side OpenGL offloading via GLX forking.
It is currently intended to be used alongside Bumblebee and provides a drop-in replacement
for optirun (i.e. "primusrun").
VARIABLES
The following is a list of environment variables affecting primus library that may be
relevant for end users:
PRIMUS_SYNC
Readback-display synchronization method (default: 0)
0: no sync, 1: synced, display previous frame, 2: synced, display latest frame
PRIMUS_VERBOSE
Verbosity level (default: 1)
0: only errors, 1: warnings, 2: profiling
PRIMUS_DISPLAY
The secondary Xorg server display number (default: :8)
EXAMPLES
primusrun glxgears -info
Runs the graphics demo supplied by mesa-utils to confirm whether the discrete card
is being used for GL rendering.
PRIMUS_VERBOSE=2 primusrun glxgears
Runs the graphics demo supplied by mesa-utils with verbose output from primus.
vblank_mode=0 primusrun glxgears
Disable vblank synchronisation, typically used for benchmarking purposes.
ISSUES
Since compositing hurts performance, invoking primus when a compositing WM is active is
not recommended. If you need to use primus with compositing and see flickering or bad
performance, synchronizing primus' display thread with the application's rendering thread
may help.
PRIMUS_SYNC=1 primusrun ...
This makes primus display the previously rendered frame. Alternatively, with PRIMUS_SYNC=2
primus will display the latest rendered frame, trading frame rate for reduced visual
latency.
