Revision as of 14:32, 24 August 2007
I received a Lemote Fulong on August 21st, 2007. Here is everything that I have learned about it so far:
Contents
HPL
Testing the machine with HPL requires a number of sub-programs to be installed.
mvapich
First on the list is mvapich2, which handles the MPI protocols needed in HPL.
Downloaded the latest and greatest version from http://mvapich.cse.ohio-state.edu/, mvapich2-1.0-beta.tar.gz.
Running Configure on this went well, so now I am going to time the compilation via make.
real 5m46.017s user 4m56.720s sys 0m40.552s
Also had to do configure with the following option:
./configure --enable-threads=single
Apparently threading is not a happy camper with this processor. Not that big a deal since in this case there is only one processor, but still....
Despite all of this, I was not able to get it to work, and since this is all really to get HPL working, I am going to fall back to MPICH instead.
mpich2
Grabbed mpich2 from the following website: http://www-unix.mcs.anl.gov/mpi/mpich2/
VSIPL
Normally I would have used BLAS, but the BLAS website was down, so I am going to try using VSIPL instead. The libraries built fine and I installed them into /usr/local/lib.
HPL Configuration
The HPL makefile configuration that I used is Make.mipsel.
sources.list
I recently changed the sources.list to point to the following:
deb http://mirrors.kernel.org/debian/ unstable main non-free contrib
I have now set off a apt-get update; apt-get upgrade, and will see what happens. This may break things, but in the meantime things appear to be alright.
This appears to have worked! Now I am going to do a dist-upgrade and cross my fingers!
Dangers
X-server
The most recent versions of the X-server are not happy additions at this time. Don't try them. X-server has a tendency to crash. In order to recover from this I went back to the X-server that was originally installed by doing the following:
- Mount the install CD via NFS. I assume that the way to install from this disk is either via a USB cdrom drive or via some sort of tftp transfer.
- Once the disc is mounted, navigate to <mnt-point>/pool/main/x/xorg and use the following command:
dpkg --install * ../xserver-xorg-*/*
gcc
An odd thing about the g77 package is that it does not appear to have an actual executable called g77. There is one that is called g77-3.4, but there is no symbolic link to this for simple g77. I had to create one and throw it into /usr/local/bin.
network-manager
Well, one of the dangers of doing something like this remotely is when the network manager gets reinstalled, and part of the re-installation is stopping that network manager:
Selecting previously deselected package network-manager. Preparing to replace network-manager 0.6.4-6 (using .../network-manager_0.6.4-8_mipsel.deb) ... Stopping network connection manager: NetworkManager
Poof! Away goes network, and thus my connection. So I am stuck until I get home and continue the install locally.
Changes
/etc/login.defs:
Lost a path to /usr/X11/bin and /usr/X11/sbin.
/etc/init.d/checkroot.sh:
Lot of changes here, and I am not sure if this is a good thing. The old script was doing some things that the new script does not do at all, and I have to wonder if these are Fulong specific.
Out of the Box
By default out of the box, the Lemote Fulong comes installed with a modified version of debian. This is not really a bad thing, but it does have some odd things about it that are not part of a default install of debian (at least, not in my experience!)
- It is setup to boot straight into X. While this is not strange in and of itself, what is strange is that it boots straight into a user account with no password, using autologin via gdm.
- The root account is configured with a password. There is paperwork in the box with the machine detailing what the account passwords are and all, but if you are like me and cannot read Chinese, it might be a bit hard to decipher. As such, the password for the root account by default is "loongson".
- By default the network interface is configured for a static IP. I unfortunately deleted that portion before I got to writing this up, so I don't know what the exact IP is, but I do know it was one of the typical 192.168.0.x IP's.
