Hello,
I have a problem : memory disappears (leaks) during calculation,
code:
===============================
ClearAll["`*"];
$HistoryLength = 0
n = 5;
Do[bound = Table[{wsk, Integrate[Sin[p], {p, 0, 3}]}, {wsk, 1, 100}];
ClearAll[bound];
Print[MemoryInUse[]]
,{st, 1, n}];
=================================
output:
----------------------------------
24971664
25168576
25365240
25593976
25789224
----------------------------------
When I used simple calling function ( Sin[] instead of Integrate[Sin[]]
this effect didn't occure.
I tried $HistoryLength = 0, ClearAll[bound] and also with no effects
In my real calculation I used more complicated function . I tried to obtain
tables of numerical intergrated functions and I was saving it step by step to the file.
After many steps my all memory leaked and server crashed ( 48 GB RAM)
The table "bound" contained only 50 numerical results of integration per one step
(system Linux Scietific , Fedora, Ubuntu)
Have you any ideas ?
With Best Regards, Olaf
