We are evaluating the purchase of a 64-bit platform for IDL.
The Apple Powermac G5 does not support 8 GB of RAM for a single process
so far and no one at Apple , and the performance of IDL under X11 is
slower than on a simple IBM Thinkpad running the Windows IDL version, so
we are getting ready to move. Of course, the G5 is very productive on
all other fronts, and "we all hope" that in due time, the G5 will become
the prime 64-bit-visualisation system in scientific computing.
There's no 64-bit-Linux support because those developments are probably
too recent, there's no 64-bit Windows so far, so we're left with a
choice of Unix platforms.
What we want to do is analyze, work with, and visualise, 3D-volume data
that ranges around 900 MB to 2.5 GB.
Which are your recommendations?
- AIX: As I saw on older posts on this list, AIX was ready to be dropped
from IDL customer support. What's the current situation? Is AIX having a
large customer base @ RSINC, or are the numbers dwindling? Is IDL under
AIX on current IBM systems, such as the Intellistation Power 275, very
fast? The Power 275 seems to be rather fast according to the Spec2000
(www.spec.org). Can someone confirm this, maybe include a time_test2 times?
- SGI: Is IRIX still a main system supported by RSI, or are they getting
ready to drop that, too? As far as I found, this board did not report
too many negative experiences with SGI. On the other hand, these systems
are very expensive.
- Solaris: Are Sun Blade workstations a good choice? Is Solaris very
common among IDL users?
- HP/UX: What about the Itanium support? Itanium 2, maybe? No news by
RSI yet, right?
Thank you very much for any suggestions on how to choose a good 64-bit
workstation for IDL,
Wolf Schweitzer.
