Hi, I'm mostly sure that the crashes we are seeing in UFRaw are related to OpenMP.
I've just added glib/gdk thread support to CVS, but I'm not really sure it is needed. It seems that the current OpenMP implementation in UFRaw is careful not to call most GTK functions in parallel. The ones that are not protected seem really naive, like gdk_pixbuf_get_width(). I've also tried replacing calls to g_idle_add_full() with gdk_threads_add_idle_full(), but it crashes immediately. I really don't understand how OpenMP and GDK's threads interact. Maybe we need to set gdk_threads_set_lock_functions() to use OpenMP locks. I'm also wondering about our parallel calls to cmsDoTransform(). I think lcms requires the use of different transforms in different threads, but I didn't see any problems in this area. All the crashes seem to be glib related. Any help on these issues would be most welcome, Udi ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
