Hi all,
I need your help! I have taken over a parallel network have 8 nodes
installed on it. However, the version of LAM/MPI on each node is too old
(6.5.6). I am going to upgrade it to 7.0. However, I have a little bit
worrying about the upgrading will destroy some configuation. I have tried it
in my own computer. I find that if just install the new version to cover the
old one. When I run lamboot, it still call the old version. On the other hand,
I also try to add my own computer (with 7.0 installed) to the parallel network.
It seems that different versions of LAM are not compatible ????. So
1) What's the correct way to upgrade LAM/MPI(All the release are installed
with compliation in tar and the source was delected)?
I am using Redhat 7.2. Some libraries needed in LAM 7.0 maybe too old, isn't
it? Should I upgrade the libraries (like glibc, openssh, etc.) first?
2) Because I can't run 7.0 in a 6.5.6-network, so I have also tried a lower
version 6.5.9 in rpm format. It's werid that after installion, though it's all
right to boot LAM, running the MPI program have some problem. Besides ouputing
the results, I also got some message like "Something wrong in the binary ...,
you have to fix it first..."
I am sorry for my long question. Thanks in advance.
