The App Trace Roll can be installed during the frontend installation step of your cluster (refer to section 1.2 of the Rocks usersguide). If this method is chosen, then the App Trace Roll is added to a frontend installation in exactly the same manner as the required OS Roll. Specifically, after the OS Roll is added, the installer will once again ask if you have a Roll (see below). Select 'Yes' and insert the App Trace Roll.
The App Trace Roll can also be added to running frontend. Here's the procedure for an x86_64 cluster (for an i386 cluster, substitute x86_64 with i386).
# cd /tmp # wget http://www.rocksclusters.org/ftp-site/pub/rocks/extras/4.1/x86_64/app-trace-4.1-0.x86_64.disk1.iso # mount -o loop app-trace-4.1-0.x86_64.disk1.iso /mnt/cdrom # cd /home/install # rocks-dist --install copyroll # umount /mnt/cdrom # rocks-dist dist # kroll app-trace > /tmp/app-trace-install.sh # sh /tmp/app-trace-install.sh |
Now install your compute nodes (or re-install your compute nodes if you added the roll to a running system).
