Thread: LAM: RHEL4 and lam 7.0.6 problem

2006-05-18 09:54:00

Hi again.......

Sorry that in the last email I did not remember to change the subject.......

Hi !

A little update to the latest message;
I removed the lam706 supplied with the RHEL4 installation and downloaded+installed from RHN a 6.5.9 X86_64.
Magically, just by doing that, DYNA started working like a dream.

Now, the doubt is:
does a program built for using a version of lam (in this case 6.5.9) work only with that particular version and NOT with higher versions ?
Or, are there some other problems not allowing the above ?

Puzzled.........

Cheers

Does anybody have an idea on how to solve the problem ?
Any help will be greatly appreciated !

I'm not sure what you mean - the above information looks perfect.  Lamboot should exit when it's done, and it looks like it finished as expected.  It started a univers on the node "redhat2" with a "cpu count" of 2. Once lamboot is finished, you can run lamnodes to see what nodes are in the newly booted environment, mpirun to run processes, and lamhalt to take down the environment. Are one of these commands not working properly?

The version of liblam and the LAM run-time environment must
match.   
So if your app is statically linked against LAM 6.5.9, you
need to  
use the LAM 6.5.9 run-time.
