please check the mailing list, just within the last few month there were many requests and answers about the same or nearly the same issue.
By the way, I still use the 11.1.075 version of the Intel compiler that causes no troubles with Wien2k (as registered user one can download it still from Intel) and I did not see that it creates much slower executables compared to 12.xxx composer versions (Never change a winning team). Unexperienced users always should avoid using the latest updates without knowing how to "repare" bugs especially if they are regularly reported in this forum. (Note: new Versions are not automatically better just because an update is available) Ciao Gerhard ==================================== Dr. Gerhard H.
