I downloaded the code in the previous mail. After some minor path adjustments, I was able to get the test program to compile and link under FreeBSD 6.1 running on a dual-processor PIII system, linked against a threaded tcl 8.5a. I could get this program to consistently do one of two things: - dump core - hang seemingly forever but absolutely nothing else.
Mike,
when zoran annouced the version, i downloaded it and had similar expericences. Fault 1 turned out to be: The link of Zoran lead to a premature version of the software, not the real thing (the right version is untarred to a directory containing
the verion numbers). Then zoran corrected the link, i refetched, and .. well no makefile. Just complile and try: same effect. Fault was, that i did not read the README (i read the frist one) and compiled (a) without -DTCL_THREADS . i had exectly the same symptoms. correcting these configuration isses, the program works VERY well.... i tried on 32bit and 64bit machines (a minor complaint in the memtest program, casting 32bit int to ClientData and vice versa) -gustaf PS: i could get access to an 64-bit amd FreeBSD machine on monday, if there is still need... PPS: strangly, the only think making me supicious is the huge amount of improvement, especially on Mac OS X. I can't remember in my experience having seen such a drastical performance increase by a realitive litte code change, especially in an area, which is usually carefully fine-tuned, and where many CS grads from all over the world writing their thesis on.... I would recommend that Vlad and Zoran should write a technical paper about the new allocator and analyze the properties and differences....
