New subject: phenixbb Digest, Vol 79, Issue 4

14 Jun 2012

      "A 64bit operating system" can only run on hardware that supports 
64bits. Here, 64bits refers to addresses in memory - arrays larger than 
4GB need 64bit addressing because 32bits do not allow high enough 
numbers to index such arrays.

It has nothing to do with the maximum value of an integer - that is set 
by the programmer.
A programmer can (depending on programming language and compiler) 
usually decide whether integer numbers should be of size 4 bytes or 8 
bytes. It is just by coincidence that 8 bytes are 64 bits.

Here it seems to me that a 8byte integer would be needed to hold the 
number of cubicles.

best,

Kay

I'm encountering the following during the second macro-cycle in
phenix.refine in latest 1.8-1069 dev build for Linux 64-bit:
RuntimeError: Excessive number of cubicles:
?This may be due to unreasonable parameters:
? ?cubicle_edge=5
? ?space_span=(8467.78,8440.85,8372.67)
? ?n_cubicles=(1694,1689,1675)
? ?max_number_of_bytes=101542821888
Any thoughts/suggestions much appreciated.
If I'm interpreting the code correctly, this means that the number of
cubicles will lead to an integer format overflow - which I find hard
to believe if you're using a 64-bit system.  Could you please send me
the rest of the error message, along with the output of the command
"boost_adaptbx.show_platform_info"?
thanks,
Nat
