I just installed the trial version on an Ubuntu 14.04 LTS system with an AMD Kaveri APU. I’m using the recent “Omega” release driver.
I’m compiling a simple OpenACC matrix multiplication example; but, I’m getting a very strange error. Does anyone have any suggestions?
$ pgcc -acc -ta=radeon test.c -Minfo=all
