Hi all,
I have a testing problem of MPICH and LAM/MPI on RHEL AS 3 (*ia32*)*, not IA64*
This is my cluster environment for testing OSCAR 4.0b6r2801.
- OS : RHEL (Red Hat Enterprise Linux) AS (Advanced Server) release 3 (Taroon Update 3).
- Kernel : 2.4.21-20.EL
- NFS : nfs-utils-1.0.6-31EL
- MySQL server : rebuilt from the mysql src rpm
ftp://ftp.redhat.com/pub/redhat/linux/enterprise/3/en/os/i386/SRPMS/
- /etc/exports on my head node
/home 192.168.0.6/255.255.255.0(async,rw,no_root_squash)
- /home of /etc/fstab on the client node
nfs_oscar:/home /home nfs rw 0 0
- rpcinfo
[EMAIL PROTECTED] root]# rpcinfo -p | grep nfs
100003 2 udp 2049 nfs
100003 3 udp 2049 nfs
100003 2 tcp 2049 nfs
100003 3 tcp 2049 nfs

I have two testing failures (MPICH and LAM/MPI) at step 8 "Test Cluster Setup".
The superficial reason that I can figure out is passing the time limit (30 sec).
However, there is no reason for MPICH and LAM to have this long compile time and
I checked to see if it takes this much time to compile lam codes on the client nodes.
Surprisingly, it takes more than a miniute to compile the cpi, which is about a 100 line C program.
I checked if this kind of thing happens in the other normal C programs. And yes, it does.
So, I think that the problem can be NFS.
Please, can anyone, who has the RHEL AS 3 (IA32), test the new SVN version of OSCAR or oscar-4.0br2801 posted
by Thomas and check to see if you have the same problem whether or not you have the exactly same environment
as I mentioned above?

As far as I have tested, RH9 and FC2 have never this problem. Several persons confirmed that there is no
this problem on RH9 and FC2.
I have two persons with RHEL AS 3 (IA64) but not IA32 and they don't have this problem.
I appreciate if you can test and share some idea.
Regards,
DongInn.
