Users of IDL:
I am still conducting a speed survey for IDL using time_test2 and
graphics_times2 (available after .run time_test). I have received
results for a few workstations, and lots of PC's. A curious result
which needs more data to confirm is a difference in speed between IDL
for Linux vs. WIN 95 for similar hardware. If you have a Pentium
133-166 class machine with either of these OS's, your times could help
resolve this issue. If you had a dual boot machine with both Linux and
Windows versions of IDL, your times would be even more useful.
Painfully lacking are results from Macintoshes (I'd like to see results
for fast 604e's or G3's), very high-end workstations and PC's (newest
PII's), multiple processor machines, and a few workstation types,
including SGI. If you are using a machine in this category for IDL,
take a moment to run the test, and see how you stack up!
The form for entry is repeated here:
Make : (Make of your computer)
Processor/Speed : (Processor and speed + number of processors if >1)
Memory : (Amount of RAM in Mb)
OS : (Operating System, including version)
IDL Version : (Version of IDL used)
Video Hardware : (Video Hardware, if Known)
tt2 -- mean/geom : (Mean (= total/23) and geometric mean of time_test2)
gt2 : (Mean (= total/4) and geometric mean of
graphics_times2)
tt2 -- test 23 : (Result of tt2 test 23 (Disk I/O -- see below))
A few notes: Use time_test2 (.run time_test) on the latest version of
IDL you have. Make sure to cd to a local partition (i.e. not a network
partition, /tmp
usually is safe on unix-like systems) before running the test, or your
disk i/o results will be very skewed. Email to
jdsmith@astrosun.tn.cornell.edu for compilation.
Feel free to pass this on to anyone who might not read the newsgroup.
Thanks,
JD
