IFORT 8.1 Killed Message

[hicham_tber]

Hello, I have a big fortran code that compile fine with ifort. but trying to run it I get : KILLED message. I know that this is due to a memory problem (reducing the size of arrays I obtain any more the message) but I m working on a machine with 8 G of RAM which normally is sufficent to run the code.
any idea , explanation ?

Have you checked on whether you need to increase stack limits? How this is done will depend on your shell, and may require root privilege the first time. I guess you are using a 64-bit system, since a 32-bit system would not normally get any benefit from so much RAM.

The station is of 8 processors Intel CPU 3.20GHz i686, and Fedora Core release 5 as OS. I have increased the size of the stack section to unlimited but that dont resolve the problem
$ ulimit -s unlimited
$ ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
max nice (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 147456
max locked memory (kbytes, -l) 32
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
max rt priority (-r) 0
stack size (kbytes, -s) unlimited
cpu time (seconds, -t) unlimited
max user processes (-u) 147456
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
file locks (-x) unlimited

Here is the result of the commande size applied to the executable file

What does "uname -a" say? Which ifort compiler are you using - one under /fc or one under /fce?

[hicham_tber]

Here are the results of the commands "uname -a" and "ifort -V"

$ uname -a
Linux taylor 2.6.17-1.2187_FC5smp #1 SMP Mon Sep 11 01:32:34 EDT 2006 i686 i686 i386 GNU/Linux

As your ifort compiler is over 2 years old, it is likely to run into incompatibilities with the newer gcc and glibc supplied with FC5. Maybe enough time has elapsed that you would be permitted a fresh non-commercial version. That is not to say this can explain the particular problem you showed.

But it's work fine with others codes of the same kind

[hicham_tber]

OK it's run fine on 64 bit.
Moreover I didn't have to recompile the code with ifort for the 64bit
Thanks
