Setting Up and Starting the TotalView Server
Because TotalView can automatically launch tvdsvr, you usually do not need
to do anything special for programs that launch remote processes. When
using TotalView, it doesn’t matter whether a process is local or remote.
Some parallel programs—MPI programs, for example—make use of a starter program
such as poe or mpirun. This program creates all the parallel jobs on your nodes.
TotalView lets you start these programs in two ways. One requires that the starter program
be under TotalView control, and the other does not. In the first case, you will enter
the name of the starter program on the command the line. In the other, you will enter
program information into the File > New Program or Process > Startup Parameter
dialog boxes. Programs started using these dialog boxes do not use the information you
set for single-process and bulk server launching.
In general, when you are debugging programs remotely, the architecture of
the remote machine must be compatible with that of the machine upon
which you are running TotalView. For example, you cannot perform remote
debugging on a 64-bit Linux system if you launch TotalView from a 32-bit
Linux system. In addition, the operating systems must also be compatible.
However, TotalView supports several forms of heterogeneous debugging,
where the operating system and/or architecture differ. For example, from a
Linux x86-64 session you can debug remote processes on Linux Cell.
This table shows the supported combinations:
Host System Target System
Linux x86-64 Linux x86
Linux x86-64
Linux Power 32
Linux Power 64 / Cell
SiCortex
Cray XT
Linux x86 Linux x86
Linux Power 32
Linux Power 64 / Cell
Linux Power 64 Linux Power 32
(including Linux Cell) Linux Power 64 / Cell
Blue Gene
SiCortex Linux x86-64 Linux MIPS 64
You must install TotalView for each host and target platform combination
being debugged.
The path to TotalView must be identical on the local and all remote systems. If they are
not, TotalView will not find the tvdsvr program.
TotalView assumes that you will launch tvdsvr using rsh. If rsh is unavailable,
you should set the TVDSVRLAUNCHCMD environment variable to the
command that you use to remotely access the remote system. In most
cases, this will be ssh.
