: After doing so, I can see messages like:
: >>>>>The file (....) is openned in RAM (*nux fd= 5 ). Activation code = 1. Total number of files in RAM is 1
Yes. it is activated.
Note, that if you have a fast drive, SDD or plenty of RAM - the speed up will be minimal. The feature has been developed for lustre-like system..
: Does it make a difference if I edit $MOLCAS/data/caspt2.prgm (or ~/.Molcas/caspt2.prgm - just for myself) instead of $MOLCAS/src/Driver/caspt2.prgm.src (BTW, there is not file named `caspt2.prgm.init' in my installation)? If so, can you explain the difference (or just point me to the appropriate page in the manual).
yes, .src (sorry for a typo!) is the source, which is compiled (to be precise - preprocessed) into .prgm during make. so, if you edit .prgm file it is OK, but it will be overwritten if you type make. and if you edit .src - you have to do make!
