Hello,
Is it true that R-1.6.0 compiled under 64-bit is less efficient on using
memory than compiled under 32-bit?
Here are my observations:
1. I have an SGI IRIX box (2Gb RAM) running 32-bit version of R-1.5.0. It
CAN handle a large data set (an 1111000 * 18 array).
2. For the same data set, on an IBM AIX 64-bit box (64GB RAM) with the new
version of R-1.6.0, it gives an out of memory error.
I am not sure if the problem is caused by 32-/64-bit compilation, or other
AIX vs IRIX issues.
Can the AIX problem be solved by compiling R-1.6.0 under 32-bit?
Thanks!
Simon
