Solved: Re: Error message when I ran the Proc iml

when I ran the proc iml,

the log showed the following error message:

ERROR: (execution) Unable to allocate sufficient memory. At least 0 more bytes required.

What does this suggest the possible problem?

Thank you,

Usually that error message indicates that PROC IML has exhausted the RAM on your computer. See

I'm a little puzzled though, because usually the message says "At least 12345678 more bytes required."

How big are the matrices you are trying to allocate? Can you include the 5-10 lines of the Log prior to the error message?

TThe matrix I want to create is around 30,000 by 30,000.

i Read your suggested blog,it can not fit into a 2 gb ram, right?

what should I do then to finish this computation?

break the original data into several sub datasets?

thank you.

Can you say more about what you are trying to do? Maybe post your code or show a small example?
