Tel Aviv, Orsay, Stockholm, Rome, Budapest, Magdenburg, Louvain-La-Nouve and Aston. Would like to run distributed applications, measurement and simulations. Would like to run distributed applications, measurement and simulations. Problems of users and node management Problems of users and node management No system wide login, 8 different sys admins, No common OS, 8 different firewalls, No system wide monitor No system wide login, 8 different sys admins, No common OS, 8 different firewalls, No system wide monitor

2nd European PlanetLab Meetings, EPFL, Oct. 2005 Proposed Solution Install a private PlanetLab network across all clusters. Install a private PlanetLab network across all clusters. Maintain one PLC for all user and node management. Maintain one PLC for all user and node management. Move existing software from PlanetLab to our clusters. Move existing software from PlanetLab to our clusters. Examples: P-Grid, Mozart/OZ, Julia, etc. Examples: P-Grid, Mozart/OZ, Julia, etc. Educate users to work in the PlanetLab environment. Educate users to work in the PlanetLab environment.

2nd European PlanetLab Meetings, EPFL, Oct. 2005 Hardware challenges Different hardware drivers/ kernel models needed Different hardware drivers/ kernel models needed IBM eServer blades have a common USB bus IBM eServer blades have a common USB bus One CD-ROM and floppy drive for 14 blades One CD-ROM and floppy drive for 14 blades Keyboard/mouse are on USB bus Keyboard/mouse are on USB bus PlanetLab does not support USB/SATA PlanetLab does not support USB/SATA Booting from a USB disk on key is not supported Booting from a USB disk on key is not supported Currently a PlanetLab node boots from a fixed CD- ROM drive, and reads the config file from the floppy drive. Currently a PlanetLab node boots from a fixed CD- ROM drive, and reads the config file from the floppy drive.

2nd European PlanetLab Meetings, EPFL, Oct. 2005 Current project status PLC Installed at HUJI, Jerusalem PLC Installed at HUJI, Jerusalem Managed to install on one node in HUJI, and one blade in TAU (11.10.05) Managed to install on one node in HUJI, and one blade in TAU (11.10.05) Major changes relative to the PlanetLab software. Major changes relative to the PlanetLab software. Modified boot cd Kernel to support hardware Modified boot cd Kernel to support hardware Modified install scripts to load additional hardware modules Modified install scripts to load additional hardware modules Changed installation to override floppy and CD- ROM drives Changed installation to override floppy and CD- ROM drives

2nd European PlanetLab Meetings, EPFL, Oct. 2005 Security issues Blades are in highly secure environment (closed computer rooms) Blades are in highly secure environment (closed computer rooms) Local System Admins are very nervous about exposed machines on their networks (no firewall, etc). Local System Admins are very nervous about exposed machines on their networks (no firewall, etc). EverLab nodes share a common switching fabric with other blades EverLab nodes share a common switching fabric with other blades EverLab nodes will be separated in a different VLAN EverLab nodes will be separated in a different VLAN
