Increasing Quantlib and Quantlib-swig-JAVA loglevel
 
|
Hello, and thanks in advance for feedback. Is there a setting, can we use, to increment LOG verbosity of the quantlib and quantlib-swig libraries ? We're using the C++/Quantlib64bit + Quatlib-swig-Java 64 library and we have some rare crash but we're not able to collect any information on it.

Hello, sorry, there's no setting to enable logging. I'll make a guess though: might your crashes in Java be related to the problem described by Klaus at <http://hpcquantlib.wordpress.com/2012/02/27/quantlib-swig-and-a-thread-safe-observer-pattern-in-c/> and <http://hpcquantlib.wordpress.com/2013/07/26/multi-threading-and-quantlib/>?

Hello, thanks for feedback. We followed the procedure described in the two links. We're using Visual Studio 2012 to compile both the QuantLib1.4 and the QuantLib-SWIG. Step followed 1) enabled for the QuantLib Solution the BOOST_SP_ENABLE_DEBUG_HOOKS preprocessor directive 2) Replaced the files observable.hpp and observable.cpp (got from here ) and rebuild the entire QuantLib library 3) enabled for the QuantLib-swig Solution the BOOST_SP_ENABLE_DEBUG_HOOKS preprocessor directive (maybe this is wrong but we failed also without the directive) 4) restart build for the QuantLib-SWIG solution. we had following errors (here just a row of the error list) QuantLib::Observer::unregisterWith(class boost::shared_ptr<class QuantLib::Observable> const &)" (?unregisterWith@Observer@QuantLib@@QEAA_KAEBV?$shared_ptr@VObservable@QuantLib@@@boost@@@Z) unresolved external -- It seems that the new quantlib did not considered the preprocessor directive 5) we have done some different attempts changing the directive inside the QuantLib-swig Solution without success Where do you think we had done some error ? Thanks in advance, Cheers.

Hi
two question which might help to debug your issue: 1) Have you added observer.cpp to your visual studio solution? 2) Does the test-suite work?
I'd suggest to change the preprocessor directive in ql/qldefines.hpp because this will define it in all other projects (e.g. SWIG). In addition I'd use the code from the later post because the first version of the patch will not work with recent boost versions (Please also read/follow the Iraki's commects. If needed I can summaries his changes for windows and my patch in a zip file.).
Another way to solve the observer pattern issue with SWIG is to delete the observers in your java/c# application manually using the delete method on the java/c# object. If you do this carefully then you don't need to patch your quantlib librarry.
regards Klaus

QuantLib application memory increase
|
|
In reply to this post by roberto.abati
Hello to all, we are using Quantlib and we're experiencing what we suppose to be a Memory Leak. Environment: - Quantlib 1.4 compiled in Windows with Visual Studio 2010 and 2012 - QuantLib 1.4SWIG compiled with Visual Studio 2010 and 2012 - applied patch to implement a thread safe QL, in windows, following Klaus Spanderen suggestions - QuantLib 1.4 JAVA compiled and executed with JAVA 1.7 - we run the application using QL DLL in a windows 2008R2 server environment Here below a list of the objects that we use inside the QL: Class=org.quantlib.Date class="org".quantlib.Period class="org".quantlib.TARGET class="org".quantlib.Schedule class="org".quantlib.DayCounter class="org".quantlib.OneDayCounter class="org".quantlib.Thirty360 class="org".quantlib.Actual360 class="org".quantlib.ActualActual class="org".quantlib.Actual365Fixed class="org".quantlib.SimpleDayCounter class="org".quantlib.DoubleVector class="org".quantlib.FixedRateBond class="org".quantlib.UnitedKingdom We see that the memory is increasing and, in a market day, reaches 12GB. Maybe there is a memory leak inside the DLL. Investigating the Memory leak we saw that: - JAVA part does not have ML (the memory well behave) so we think that the ML is into the DLL c++ part. - while memory with QL 1.4 increases fast, the QL 1.1 present a memory increase trend almost "perfect" (there is an increment but is acceptable) - we're doing other investigation to identify the not released objects. Do you have any suggestion ? Presents a so complex situation in a mail is almost impossible so we're available to provide to you any trace you need.

Hi
IMO it is unlikely that this is a QuantLib issue. Does this memory leak also exist if you don't use the thread safe SWIG patch? Maybe it is the patch and not the difference between QL 1.1 and QL 1.4?

Hello Klaus and thank-you for the answer. Maybe the issue is in the patch but we were not able to test our server without the patch. We discovered the issue working with 5K instruments and with a fast market (for bonds + futures) re-player. With these parameters the non-patched server+QL runs few minutes and then crashes. The 1.1 we're currently using does not present any multithread issue and also memory increases but slowly.
