[Pw_forum] cluster timing & delay -v.lousy way-

[GAO Zhe]

Yambo can be easily compiled with QE-4.x in Debian-based system, but with a makefile problem in RedHat-based system (lack of seperator '\'). However, you can compile it seperately, i.e., download Yambo-code fromhttp://www.yambo-code.org/ and compile.
Actually, I reported this problem in Yambo's forum half year before~

Dear Changru,

Since there are other programs included such as Yambo which are not compatible with the recent version of Q.E. , this version is used
