Cray XT Installation

Install MemoryScape where it is visible from your Linux login nodes. Do not install MemoryScape on your compute nodes. MemoryScape communicates with these nodes using a library created Cray.

When you install MemoryScape on a Cray XT CNL system, the Install script begins by unbundling the tar file. It then invokes the rpm files contained within it. In contrast to the standard MemoryScape installation, the Cray installation doesn’t ask where it should install MemoryScape as it knows where to install files.

The Install script also places the Cray bulk launching system and other support modules within the installation directory.

TotalView on Cray XT systems use totalview-support product components to provide essential interface components that allow TotalView to execute in Cray environments. Included within totalview-support are the totalview-support module, a configuration file, and a set of bulk launcher executables.

The bulk launcher is a paired set of executables that use ALPS to scalably launch the TotalView Debugger Server (tvdsvr) executable on compute nodes.

If you are running your program on an XT3 Catamount system

The tvdsvr process is called tvdsvr_rs.

In many cases, you will need to use the –nodes_allowed server command-line option to tvdsvr_rs.

Your environment must set the RS_DBG_CLIENTS_PER_SERVER variable.
