I am particularly interested in how your pool of threads manages socket connections. Are these threads dynamically created to manage connections? That is, do you n+1 threads managing your connections, where n is active connections plus one to handle connection requests on the master socket? Are sockets blocked or do you use some other method of activating threads? <snip> > > Well, given an SMP machine, with an OS that will intelligently distributes > threads -- that all semi happens for free with me (its not quite so good > as I try to minimise thread creations, as few to no current OS'es will > migrate a thread across processors for load sharing).

It is my understanding that many OSs that implement multi-processing will allocate one CPU for the OS and the rest of the available units to application threads. NT 3.51 does this as well as many Unixes. I thought OS2 used this model also. (please correct me if I'm wrong) It is also my understanding that NT 4.0 uses a different model and implements "load sharing" as you define it above. I have heard rumors that Digital's 64-bit Unix uses the "load sharing" model. Does anyone have any info on this? </PRE> <!--X-Body-of-Message-End--> <!--X-MsgBody-End--> <!--X-Follow-Ups--> <HR> <!--X-Follow-Ups-End--> <!--X-References--> <!--X-References-End--> <!--X-BotPNI--> <UL> <LI>Prev by Date: <STRONG><A HREF="msg00087.html">Re: mud grammar</A></STRONG> </LI> <LI>Next by Date: <STRONG><A HREF="msg00089.html">Re: Just a bit of musing</A></STRONG> </LI> <LI>Prev by thread: <STRONG><A HREF="msg00086.html">Re: Just a bit of musing</A></STRONG> </LI> <LI>Next by thread: <STRONG><A HREF="msg00089.html">Re: Just a bit of musing</A></STRONG> </LI> <LI>Index(es): <UL> <LI><A HREF="index.html#00088"><STRONG>Date</STRONG></A></LI> <LI><A HREF="thread.html#00088"><STRONG>Thread</STRONG></A></LI> </UL> </LI> </UL> <!--X-BotPNI-End--> <!--X-User-Footer--> <!--X-User-Footer-End--> <ul><li>Thread context: <BLOCKQUOTE><UL> <LI><STRONG>Re: Just a bit of musing</STRONG>, <EM>(continued)</EM> <ul compact> <LI><strong><A NAME="00078" HREF="msg00078.html">Re: Just a bit of musing</A></strong>, Adam Wiggins <a href="mailto:nightfall#inficad,com">nightfall#inficad,com</a>, Sat 08 Mar 1997, 19:10 GMT </LI> <LI><strong><A NAME="00079" HREF="msg00079.html">Re: Just a bit of musing</A></strong>, Adam Wiggins <a href="mailto:nightfall#inficad,com">nightfall#inficad,com</a>, Sat 08 Mar 1997, 19:19 GMT </LI> <LI><strong><A NAME="00080" HREF="msg00080.html">Re: Just a bit of musing</A></strong>, Chris Gray <a href="mailto:cg#ami-cg,GraySage.Edmonton.AB.CA">cg#ami-cg,GraySage.Edmonton.AB.CA</a>, Sun 09 Mar 1997, 01:34 GMT </LI> <LI><strong><A NAME="00086" HREF="msg00086.html">Re: Just a bit of musing</A></strong>, Chris Gray <a href="mailto:cg#ami-cg,GraySage.Edmonton.AB.CA">cg#ami-cg,GraySage.Edmonton.AB.CA</a>, Tue 11 Mar 1997, 13:45 GMT </LI> <LI><strong><A NAME="00088" HREF="msg00088.html">Re: Just a bit of musing</A></strong>, Jon A.
