+/* syncdemo - a program to demonstrate the performance and validity of different
+ * synchronization methods as well as some timing properties.
+ *
+ * The task to be done is very simple: a single gloabl integer is to to incremented
+ * by multiple threads. All this is done in a very-high concurrency environment. Note that
+ * the test is unfair to mechanisms likes spinlocks, because we have almost only wait
+ * time but no real processing time between the waits. However, the test provides
+ * some good insight into atomic instructions vs. other synchronisation methods.
+ * It also proves that garbling variables by not doing proper synchronisation is
+ * highly likely. For best results, this program should be executed on a
+ * multiprocessor machine (on a uniprocessor, it will probably not display the
+ * problems caused by missing synchronisation).
+ *
+ * Note: partitioned processing mode means that all computation is first done
+ * locally and the final result is then combined doing proper synchronization.
+ * This mode is used as a baseline for uninterrupted processing.
+ *
+ * compile with $ gcc -O1 -o syncdemo -lpthread syncdemo.c
+ *
+ * Alternatively, you may use -O0, but not a higher level. Note that
+ * the gcc code generator does in neither case generate code really
+ * suitable to compare "part" and "none" modes. If you absolutely need
+ * to do that, you need to use inline assembly. However, the results should
+ * be fairly OK when consitently using either -O0 or -O1. If you see a big loss
+ * of performance when you compare "none" and "part", be sure to run
+ * "none" with -t1 and watch out for the results! In any case, looking at the generated
+ * assembly code is vital to interpret results correctly. Review of generated assembly
+ * done on 2010-05-05 indicates that -O0 is probably the best choice. Note that we
+ * use the volatile attribute in one spot. This is used because it results in the
+ * best comparable result for our gcc 4.4.3, not really to invoke the volatile semantics.
+ *
+ * use "gcc -g -Wa,-ahl=syncdemo.s -lpthread syncdemo.c" to obtain a mixed code/assembly listing.
+ *
+ * This program REQUIRES linux. With slight modification, it may run on Solaris.
+ * Note that gcc on Sparc does NOT offer atomic instruction support!

-/* This takes a received message that must be decoded and submits it to

- *
- * rgerhards, 2006-11-30: I have greatly changed this function. Formerly,
- * it tried to reassemble multi-part messages, which is a legacy stock
- * sysklogd concept. In essence, that was that messages not ending with
- * \0 were glued together. As far as I can see, this is a sysklogd
- * specific feature and, from looking at the code, seems to be used
- * pretty seldom (if at all). I remove this now, not the least because it is totally
- * incompatible with upcoming IETF syslog standards. If you experience
- * strange behaviour with messages beeing split across multiple lines,
- * this function here might be the place to look at.
- *
- * Some previous history worth noting:
- * I added the "iSource" parameter. This is needed to distinguish between
- * messages that have a hostname in them (received from the internet) and
- * those that do not have (most prominently /dev/log). rgerhards 2004-11-16
- * And now I removed the "iSource" parameter and changed it to be "bParseHost",
- * because all that it actually controls is whether the host is parsed or not.
- * For rfc3195 support, we needed to modify the algo for host parsing, so we can
- * no longer rely just on the source (rfc3195d forwarded messages arrive via
- * unix domain sockets but contain the hostname). rgerhards, 2005-10-06
- *
- * rgerhards, 2008-02-18:
- * This function was previously called "printchopped"() and has been renamed
- * as part of the effort to create a clean internal message submission interface.
- * It also has been adopted to our usual calling interface, but currently does
- * not provide any useful return states. But we now have the hook and things can
- * improve in the future. <-- TODO!
