Hi all, I have some C++ code that I call from my package. In my main C++ loop, I check for user interrupts and return to the R shell after ensuring I've deallocated memory appropriately. This works fine when the code is compiled with gcc+openmp and with icc without openmp, but when I compile with icc and use openmp, the entire R session is immediately terminated when I hit ctrl-C. This happens even if I only have one thread and even if I set an openmp barrier just before checking for user interrupts.
When the R session terminates unexpectedly, I usually just get "Aborted" before return to the bash prompt. Occasionally, though, I get this error: OMP: Error #15: Initializing libguide.so, but found libguide.so already initialized. OMP: Hint: This may cause performance degradation and correctness issues. Set environment variable KMP_DUPLICATE_LIB_OK=TRUE to ignore this problem and force the program to continue anyway. Please note that the use of KMP_DUPLICATE_LIB_OK is unsupported and using it may cause undefined behavior. For more information, please contact Intel(R) Premier Support. But KMP_DUPLICATE_LIB_OK=TRUE changes nothing. I had a look at: http://software.intel.com/en-us/articles/opm-abort-initializing-libguide40dll/ which suggests there may be a conflict between libguide40 and libiomp5md, but I can't find any loaded R packages that link against libiomp5md... Does anyone have any ideas? Many thanks, Ernest ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
