I've used EGL for a long time now, but always with a single GPU. I understand it well.<br>
<br>
I have a new cluster with *two* GPUs on the node and a more recent driver, where I compiled 5.4 with EGL and OpenMPI<br>
<br>
Launching pvserver, and connecting I get this error:<br>
<br>
mpirun -np 1 ./bin/pvserver --egl-device-index=0 : -np 1 ./bin/pvserver --egl-device-index=1<br>
<br>
