I was trying to read up about 64bit OS and one of the thing they are pointing out is that it should be faster for some computations since all the bits would fit in one 64bit word.
My J application server in production are still using 32bit CPU's (i.e. Intel Pentium 4 3Ghz single core) and the OS(Win2K, MSSQL, IIS, etc) are all 32 bits. I've been looking at some submission by other teams and all of their requirements are still in 32bit. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of bill lam Sent: Wednesday, September 30, 2009 2:30 PM To: [email protected] Subject: Re: [Jgeneral] Advantages of using J in 64 bit OS On Wed, 30 Sep 2009, Alex Rufon wrote: > Where doing the CAPEX for 2010 and I was hoping to get a 64bit machine for my > J Application Server. > > Right now, I've only came up with the following justification: > > 1.

Assuming you work with mssqlsvr, There are already 64-bit version of window server 2008 and mssqlsvr 2008. For 32-bit os, the sqlsvr alone would eat up almost all available 4GB memory. J odbc script can run in 64-bit mode. Not sure for dotnet (I didnt use). BTW how can you possibly get a 32bit x86 cpu nowadays (except atom in netbook or some via chip). -- regards, ==================================================== GPG key 1024D/4434BAB3 2008-08-24 gpg --keyserver subkeys.pgp.net --recv-keys 4434BAB3 ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
