[edit] Development System

on VM in data center. I will use it for development before test cluster stabilizes. To ensure consistency with Rocks environment I am using rpms from standard rolls, if available. Currently they are under /home/yhal003/RPMS

OS: CentOS 4.4 IP: 130.216.189.66

[edit] Dependencies

packages not available in default rolls and needed for the distribution.

libtermcap-devel.i386

[edit] Issues

  • when run without arguments, beast needs X for file chooser. probably not an issue, but...

[edit] Globus Testing

Development machine is also set up to submit jobs on gateway.

  • To install VDT Client
    • Install prerequsites 
yum install compat-libstdc++-33.i386
    • modify /etc/hosts (should list entry that is outputed with hostname command)
      • For some reason in our case /etc/hosts listed argonne1 while hostname returned argonne4...
    • follow instructions on VDT web site
      • have to pretend to be redhat since CentOS 4 is not supported: 
pacman -get -pretend-platform linux-rhel-4 -get http://vdt.cs.wisc.edu/vdt_1100_cache:VDT-Client


[edit] Test Cluster

All nodes of test cluster are virtual machines running on Xen VM. This allows us to get 64 bit Rocks 5.0 environment, the same as on production cluster. Currently test cluster consists of frontnode and two compute nodes.

[edit] Install Notes
