Hi Everyone, I'm working on a bit of pycuda that for image processing. Today I have run into an interesting issues, when I run a high number of iterations of my code, I end up getting an error executing one of my Elementwise kernels. It is not always the same one and can happen at slightly different iterations. (these are extraordinarily simple kernels, nothing complicated)
Error: pytools.prefork.ExecError: error invoking 'nvcc --preprocess -arch sm_35 -I/usr/local/lib/python2.7/dist-packages/pycuda-2013.1-py2.7-linux-x86_64.egg/pycuda/cuda /tmp/tmplAgMsh.cu --compiler-options -P': [Errno 12] Cannot allocate memory This error is not directly in the pycuda codebase, but happens in pycuda/compiler.py in the preprocess_source function when it calls out to pytools/prefork.py see stack trace: http://pastebin.com/WQUFeTSG At this point in time I am neither out of memory on the Host(10GB+ free) nor on the Device(3GB+ free). I have the feeling this may have something to do with stack size or open file-descriptors. Has anyone seen this before?
