[Wien] Allocation error 494

[Jorissen Kevin]

This is not unusual : I run jobs of up to 1.7 Gb, also on a 4 Gb machine.
I'm afraid there's nothing to be done about it (except buy opterons or sth similar).
 
The difference between the two machines might be due to different nmatmax/nume - settings?

hello everyone

I was wondering if anyone had ever had trouble with allocation
errors on a 4G machine.  I sucessfully got a large job to start
on a 2G machine, using 1.5G RAM and 1G swap.  When I try to run
this same job on a 4G machine, I get allocation errors.  It seems
I'm having trouble using more than 2G out of the 4G of ram, and
the program is not using any swap. 

I've changed the stacksize to unlimited:

cputime         unlimited
filesize        unlimited
datasize        unlimited
stacksize       unlimited
coredumpsize    0 kbytes
memoryuse       unlimited
vmemoryuse      unlimited
descriptors     1024
memorylocked    unlimited
maxproc         7168

The 2G machine is a dual-processor (although I was only running
the job on one processor) Xeon 2.2Gz running red hat linux (kernel
2.4.18-3smp).

The 4G machine is a pentium 4 running suse (kernal 2.4.21-260-smp4G).

Thanks a lot
Best wishes

Rebecca
