Whatis Mem use for multiple instances same 32bit program on Win7 64bit
Hello,
My question stems in 2 parts.
1. If I have a primarily single threaded 32 bit application that I want to run multiple instances of on a Win 7 64 bit machine...in order to take advantage of throughput on 2xquad core cpu's
a. Will each instance of the 32 bit application be limited to 2GB of 32 bit addressable memory?
b. Will the total memory available to all of the running 32 bit applications be only 3.25GB or will a machine with say 64GB of memory parse out 32 2GB partitions to 32 unique windows of an application?
2. If the application has driver interfaces only certified in Windows XP (and not functioning in Win 7 (32 or 64 bit)), what is the impact of question 1 above on running multiple instances of the same application in XP SP3 compatibility mode (e.g. are there additional memory/graphic limits imposed)?
Thanks in advance for taking a look at my questions! :)
