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.
=============some command results=================
gbliu_at_ClusterServer:/cluster/soft/MPI/lamtests-7.1.2> lamboot -v hf

====================================================
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_at_ClusterServer:/cluster/soft/MPI/lamtests-7.1.2> make -k check

Rank (0, MPI_COMM_WORLD): Call stack within LAM:
Rank (0, MPI_COMM_WORLD): - MPI_Comm_accept()
Rank (0, MPI_COMM_WORLD): - main()
---------------------------------------------------
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
Guibin Liu
