I know that. From this massage i need ~14Gb memory. If i use 24 CPU(1Gb/core) it is not a problem....should be. But it does. From one point of view, mwords defines memory per core, but from another i need very big value (more then 1000, i checked).

I tried different numbers, like 40 ... 60 ... I didn't have any problems with CAS(14,14). Is it limitation of current version of Firefly?

Thank you very much again for your comments and suggestions.

Best, Pavel.



>>Ok, i need setup 1823 MWORDS or 13909 Mb or ~15Gb. It is ok for me, because i am going to use 24 CPU and up to 24 Gb memory (1Gb per 1 CPU). I setup mwords to 1900 and got strange behaviour of Firefly:
