Out of memory
Hello !! I wish to run a CFD commercial code on our
station (4GB Ram - HP-UX 10.2).
But each time I run a big job I receive :
out of memory or could not allocate storage.
I've seen that I should increase certain kernel parameters but I don't know
them.
I've tried to increase maxdsize but after reboot I've got error like fork : two
many processes ...
and can't do nothing, except reboot in single user and booting with old kernel.
Is there a way to allocate memory for a specific job without modifying the
kernel.
I've also read that up to 2.75GB there was problem.
Should I upgrade to HP-UX 11 ??
Thanks for advance

Re: Out of memory
you could be out of swap space.
type in swapinfo -a . Is there any available.
There is a parameter in the kernel that can allow
the physical memory to bypass the swap space
swapmem_on
ALso, you must make sure that both maxssiz and shmmax are increased along with
any other parameteres

Re: Out of memory
It works !!
I've turned on swapmem and used the parameter
provided in Tuning and performance of the HP doc !!
Thank's
Nicolas
