Use tbbmalloc_proxy

Open 1003581 opened this issue 2 years ago • 4 comments

I had a c++ code that uses tbbmalloc_proxy and this improved the performance alot on Windows 10 I packaged c++ code as python interfaceI using SWIG but it seems that SWIG ignores tbb and just uses the malloc implmenetation from ntddll.dll Any ideas how to overcome this issue ?

@1003581 did you try to use a linker option or header file option from documentation?

@1003581 did you try to use a linker option or header file option from documentation? I add tbbmalloc_proxy.h to my source code，but it dose not work.

Was this issue resolved? I am having a similar issue. I have a DLL which includes tbbmalloc_proxy.h and when called from Python, TBB's allocator is not being used. Is there any way to use tbbmalloc_proxy.dll without linking Python against it? I am only concerned with allocations inside the DLL in which I have included tbbmalloc_proxy.h.

NO. I overload the new/delete functions for specific classes, this avoids the use of ”tbbmalloc_proxy.h“. Maybe you can see if this helps. https://github.com/swig/swig/issues/2324#event-7022785347
