My version was build on gcc 2.95.2 on IRIX 6.5.6. I can't compile it with the
native cc !!!
I think that dx doesn't work on 64 bit only on 32, so you must force n32.
Can you explain your method to compile with native compile (aclocal... your
variable (PATH CFLAGS...).
The pg i run on dx, first load data from file, than make some work and
display.
My runs are "divide" in three.
During the first, there's a process dxexec (or more if -processors > 1
and dx 4.0.9. It doesn't work on more than 1 CPU with the IBM version).
During the second, my program to load data into dx work (with a level
of cpu different from version (16 % on 4.0.9, 40 % with IBM !!)
Last section work on the data and display.
The version 3.1.4 is making is jobs in 2 minutes, the 4.0.9 in 5.
Last question, do you work with the tar or cvs ?
