- Xorg should be running on all (!) cards which will be used for

computing. To generate xconfig initializing all adapters:

aticonfig --initial --adapter=all

env DISPLAY=:0.0 aticonfig --adapter=0 --od-gettemperature
11
env DISPLAY=:0.0 aticonfig --adapter=# --od-gettemperature
12
env DISPLAY=:0.0 aticonfig --pplib-cmd "get fanspeed 0"
13
env DISPLAY=:0.# aticonfig --pplib-cmd "get fanspeed 0"

* Overlapping memory transfers, set environmental variable

* AMD p2rofiler will crash if multiple adapters are used

* LD_LIBRARY_PATH=/usr/lib64 ./amd_opencl_application

or will crash otherwise

- clCreateImage2D (APPSDK 2.7) will produce invalid context which will crawsh

on access (but create terminates successfuly). Use clCreateImage instead.

- oclFFT initializes forever (APPSDK 2.7) if shared context is used.
