Poor mans way of FEA with increased Virtual Memory.

Poor mans way of FEA with increased Virtual Memory.

(OP)
If time is not an issue, is there a way to get around the limits of winodws 4GB limit on virtual memory?  I think there is.  This link talks about increases virtual memory to 64GB.
Increasing virtual memory
However I did to do more research on the topic.  What do all of you think?

RE: Poor mans way of FEA with increased Virtual Memory.

I think it would be rather slow.

I recently had the dubious pleasure of running a large-ish model (for me) on my laptop

RAM
256 Mbytes - 2 days
784 MBytes - 4 hours
1.5 Gb -  30 minutes

Since I was doing a DOE with 80 iterations I was rather keen to spend the money on the RAM and get the solve time down.

GregLocock, I agree with you.  However is there away around the 4GB limit ram or not?

RE: Poor mans way of FEA with increased Virtual Memory.

Jason, I am almost certain that the answer is NO:
1. 32-bit processors are limited to 4-Gbytes
2. the compiler might limit how much memory can access
3. Win-XP Professional has a limit of 4-Gbytes.
4. the application dynamic libraries might be compiled for 32-bit processor -- thus cannot go behond 4-Gbytes.

Any one of these limits will stop you from accessing more than 4-Gbytes of memory total.

You will need at least a 64-bit processor and the proper compilers, OS, and application to access more than 4-Gbytes.
