I am running pgfortran on macbook pro os x yosemite. I had downloaded pgfortran 15.5 for mac os x and installed it in the default location “/opt”. On compiling a test program I get the following issue.
Gokuls-MacBook-Pro:Desktop gokul$ /opt/pgi/osx86-64/15.5/bin/pgfortran test.f90 NOTE: your trial license will expire in 8 days, 23.9 hours. NOTE: your trial license will expire in 8 days, 23.9 hours. test.f90:260:no such instruction: `vzeroupper' Gokuls-MacBook-Pro:Desktop gokul$
I am running haswell. I don’t see why it is not able to recognise the instructions.
