Hi, one of my colleagues got some trouble with a program handling large amounts of data. I figured out that a 32 bit application on HP-UX cannot address more than 1 GB of memory. In fact (I think due to the overhead of memory management done by python) a python application cannot use much more than 500 MB of "real" data. For this reason I've created a 64 bit version of python 2.3.5. I've tested a simple C program before to make sure its able to address the whole available memory (8 GB main memory and about 12 GB swap). The simple example in C works, but the python script didn't. I was able to create only 2 GB of python objects. The application occupied approximately 2.2 GB of memory. After that, python failed with a memory error.
Is there any internal restriction on the size of the heap? Mathias -- http://mail.python.org/mailman/listinfo/python-list
