Dear all:
I installed lam-7.1.2 on our cluster. Each node of our cluster has a
Pentium D 945 3.4G duo-core CPU (em64t).
I installed lam to a NFS shared directory.

====================================================
It seems that lamboot was done correctly.
But when I use lamtests-7.1.2, problems occure.
Under the top dir of lamtests-7.1.2, configure and make goes successfully.
And then I do "make -k check", it hangs up at the first test and stops
there.
the output is as follow:
-----------------------output----------------------
gbliu@ClusterServer:/cluster/soft/MPI/lamtests-7.1.2> make -k check

---------------------------------------------------
After a long time, the output is still like this and the usage of CPU is 0.
I use ctrl-C to cancel it and then do command "lamnodes", but this time
lamnodes also hangs up, no output appears. Only after I do lamboot again,
lamnodes becomes all right.
I don't know what's the problem. Can someone help me?
Yours sincerely

laminfo
LAM/MPI: 7.1.2
Prefix: /cluster/lammpi-7.1.2
Architecture: x86_64-unknown-linux-gnu
As you have built your lam for x86-64 (64-bit architecture), you must
make sure you don't mix it with an incompatible lam version, or with
objects or libraries built for 32-bit architecture. Such mixtures would
produce the sort of hang you mention.
I am sure that before I install lam-7.1.2, there is no LAM installed
on my system.
But how do I check if I don't mix it with objects or libraries built
for 32-bit architecture.
I just configire , make and make install, what else should I config?
