[Beowulf] Please help test compiler/hardware issue

[James Cuff]

Hi Orion,

I'm thinking you may have bad memory/hardware on one of those nodes  
here mate...

Compiles and runs fine here in 32 bit ubuntu fiesty:

jcuff at harold:~$ uname -a
Linux harold 2.6.20-15-386 #2 Sun Apr 15 07:34:00 UTC 2007 i686 GNU/ 
Linux

jcuff at harold:~$ cat /proc/cpuinfo | grep "model name"
model name      : Intel(R) Pentium(R) 4 CPU 2.53GHz


jcuff at harold:~$ gfortran -O3 -o tt test.f90
jcuff at harold:~$ time ./tt
^C
real    8m11.766s
user    8m5.862s
sys     0m4.280s


Also your 64 bit static compiled version runs fine even on a rather  
crappy "64 bit" Celeron I have on FC 5:

[jcuff at gw ~]$ cat /proc/cpuinfo  | grep "model name"
model name      :                 Intel(R) Celeron(R) CPU 2.93GHz

[jcuff at gw ~]$ uname -a
Linux 2.6.20-1.2312.fc5 #1 SMP Tue Apr 10 15:14:58 EDT 2007 x86_64  
x86_64 x86_64 GNU/Linux


[jcuff at gw ~]$ time ./testatob
^C
real    5m5.794s
user    3m38.785s
sys     0m9.890s


Hope this helps.

Best,

j.
