Thanks for responding. The question about the RAM memory is for all computers that I have used SCIRun with. The memory just keeps been used until depleated. I was told there is a line in the SRC file that allows you to free up memory so it doesn't happen. But I was told that I need to recompile, and I don't know how to do it.
BTW, I am using a Pentium D 820 with no apparent problem, but using it with 32 bit only and so far as only what core since I have not been able to recompile.
thanks

SCIRun has been well tested on amd dual dual core machines. We recently discovered a bug with sci-malloc and 64bit buiilds.  If you are on the svn developement build sci-malloc has been disabled by defualt now.  If you have an older version of the source, use --enable-64bit and --disable-sci-malloc on your configure line. This will let you alloc as much main memory and swap as you have available.

I forgot to ask also about the AMD x2 (dual-core) processors. Please give any help.
Thanks

Subject: Dual core processors and EM64T, and RAM memory

Has SCIRun been tested with Intel Dual Core and/or EM64T processors? If I modify the SRC file, how do I recompile it?
Can anyone help on how to free up some memory when SCIRun is running many iterations? I have 3 GB of RAM and it uses almost all of it before it crashes.
Thanks for your help
