Hi folks,
The following piece of code seems to leak a lot of memory (with/without
the statement 'del X') during long runs of computation:
while true:
X = SupersingularModule(p)
X.hecke_matrix(2)
del X
p = ZZ(p).next_prime()
To pin down the souce of leakage, I incorporated the below code
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/65333
into mine
http://sage.math.washington.edu/home/burhanud/leak/leak.py
[1] When I run
load leak.py
at the sage prompt, I get the following output ad infinitum:
http://sage.math.washington.edu/home/burhanud/leak/dump.txt
Are _PolynomialRing_general, _FiniteField_ext_pariElement leaking memory?
[2] When I run
nohup sage <leak.py> tmp.txt &
from the shell prompt, sage exits in a few milliseconds due to an
Indentation Error exception.
http://sage.math.washington.edu/home/burhanud/leak/tmp.txt
Why does the leak.py run perfectly from the sage prompt but not from the
shell? Preparsing issue?
Regards,
Ifti
