Dear Thushara
the maximum memory available for all user related scoring is 48 Mbytes
minus what is used for geometry, cross section tabulations etc.
Your output is showing that indeed you have some 40 Mbytes available, the
problem is that you are asking for almost 84...
The issue is not with how many EVENTBIN/USRBIN you ask for, but with the
total number of bins among all EVENTBIN/USRBIN cards.
You can ask for single precision EVENTBIN's using the card ROTPRBIN (see
the manual) and this will laready halves your memory requirements.
EVENTBIN/USRBIN's default to double precision, but while this is often an
issue for USRBIN's since they can sum up a lot of small contributions over
a long run, it is usually not a problem to use single precision for
EVENTBIN's (but you should judge depending on your problem).
Further, if you believe that only a fraction of the allocated cells wiil
be hit in each event, you can ask the code to allocate only a subset
(again see ROTPRBIN). The price is that if an event is going to hit ALL
cells the code will stop (given the number of cells you have probably it
is unlikely).
Ciao
Alfredo
