11 years ago Hi, thanks for trying this out. Glad to know it at least compiles on Windows - I haven't tried it and it is surprising that it (even just partially) works. :-)
1) after setiing benchmark for numpy=1, the tests run, but seem to show numpy aas faster (higher gflops and lower time) than ceygen.
Hmm, what exact compiler version do you use, what Eigen version, what compiler optimizations? What are the exact benchmarks where you see suboptimal performance? For what problem sizes? For larger matrices and some operations, NumPy can be comparable and even slightly faster - depending whether it has been linked against an optimized BLAS version. What machine (processor type, number of cores and frequency) is it?
2) there are errors in a few tests..
I see. Fortunately this just fails on a very strict and artificial assert that I've put just for testing and shouldn't hurt normal use. If you type python -v install, Cython will happily install itself without testing. But still I'd like to debug it:
File "test_core.pyx", line 205, in ceygen.tests.test_core.TestCore.test_dot_mm (ceygen/tests\test_core.cpp:8683) File "core.pyx", line 108, in ceygen.core.dot_mm (ceygen\core.cpp:4620) ValueError: is_malloc_allowed() && "heap allocation is forbidden (EIGENRUNTIME NO_MALLOC is defined and g_is_malloc_allowed is false)" does not hold in C:/Ceyg en-0.2/Eigen/Eigen/src/Core/util/Memory.h:189
^^^ can you please paste what ceygen\core.cpp:4620 line is along with some context (i.e. 5 lines around)?
ceygen\llt.cpp: In function 'PyObject* get_memview_MemoryView_5array_7memview_get(__pyx_array_obj*)': ceygen\llt.cpp:3415:15: warning: dereferencing type-punned pointer will break strict-aliasing rules
This warning should go away with recent Cython, please try 0.19.
ceygen\llt.cpp:14130:78: warning: unknown conversion type character 'z' in format
This seems to be a Cython bug happening only on Windows systems.
C:\Python27\Scripts\g++.exe -DMS_WIN64 -shared -s build\temp.win-amd64-2.7\Release\ceygen\llt.o build\temp.win-amd64-2.7\Release\ceygen\llt.def -LC:\Anaconda\libs -LC:\Anaconda\PCbuild\amd64 -lpython27 -lmsvcr90 -o build\lib.win-amd64-2.7\ceygen\llt.pyd -fopenmp g++.exe: libgomp.spec: No such file or directory
This is caused by having -fopenmp in your ldflags (which is the default - set it to empty in setup.cfg). Your compiler environment doesn't seem to support OpenMP for parallelization - if it did, dot_mm could use all your cores and be much faster for large matrices.

Hi I installed ceygen 0.2 and saved the eigen folder within it.
I am using TDM GCC on windows 7. I ahve eigen downloaded and have cereated a setup.cfg to point to it.
I have two issues:
1) after setiing benchmark for numpy=1, the tests run, but seem to show numpy aas faster (higher gflops and lower time) than ceygen.
2) there are errors in a few tests..
I like the idea of ceygen and it might prove to be effective if I can ge this working!
thanks!
Edit: I also donwloaded this master branch and I got another set of errors.
