Well as a matter of fact my application is already a memory hog... Each RGBA pixel is 4 bytes and the display footprint is barely visible on some of these images. I keep image buffers in memory so...

Thanks all for very informative replies. Memory allocation at the system level is more complex than I thought. I'll dig into the mmap() possibility. Part of my design-for-performance strategy working...

I have an application that routinely alloc() and realloc() gigabyte blocks of memory for image processing applications; specifically performing rotations of huge images, or creating/ deleting huge...

Many sincere thanks. Very useful info. I admit that I have been rather cavalier slinging gigabytes of image memory around on a 64 bit machine with 8 Gb RAM, simply because I've been getting away with...

I'm rotating huge image rasters (1+ GB) using a 3-shear algorithm. I rotate 'in-place' after reallocating the raster. A necessary first step is reorganizing the image in the new raster dimensions...

I'm trying to do an upgrade/install from Solaris 8 to Solaris 10 on a SUN Sparc system.

I halt the system, as documented, but when I attempt to boot off the distribution DVD; i.e.
