What does high performance computing mean?

Sorry, I am not really from a computer science background. But from the subject of it, does it mean something like multi processor programming? distributed computing? like using erlang? Sound like it, which excite me. I just had a 3 day crash course in erlang and "Cocurrency oriented programming" sounds like the edge we need today. I will be very happy to see more activity in here.

NAME
tsung - A distributed multi-protocol load testing tool. SYNOPSIS
tsung [ -f configuration file ] [ -l log dir ] [ -m filename ] [ -r command ] [ -v ] [ -6 ] [ -h ] [ start|stop|debug|status ] DESCRIPTION
tsung is a distributed load testing tool. It is protocol-independent and can currently be used to stress and benchmark HTTP, WebDAV, LDAP, PostgreSQL, MySQL and Jabber/XMPP servers. It simulates user behaviour using an XML description file, reports many measurements in real time (statistics can be customized with trans- actions, and graphics generated using gnuplot). For HTTP, it supports 1.0 and 1.1, has a proxy mode to record sessions, supports GET and POST methods, Cookies, and Basic WWW-authentica- tion. It also has support for SSL. Several config examples can be found in /usr/share/doc/tsung/examples/. start start tsung load testing debug start tsung with an interactive erlang shell stop stop tsung status print current status of a running instance of tsung (must be run on the controller host) MANUAL
A manual should be available at /usr/share/doc/tsung/user_manual.html. It is also available online at http://tsung.erlang-projects.org/user_manual.html OPTIONS
-f filename specifies the configuration file to use. The default file name is ~/.tsung/tsung.xml. Use - for standard input -l logdir Specifies the log directory to use. The default log dir name is ~/.tsung/log/YYYYMMDD-HHMM/ -m monitoring_file Specifies the monitoring log file name to use. The default log file name is tsung.log. Use - for standard output -r command Specifies an alternative to ssh (rsh for ex.) for starting a slave node on a remote host -i id set controller id (default is empty). Needed to start several controllers on the same host. -F Use long names for erlang nodes (FQDN) -m Enable erlang smp on client nodes -v Show version -6 Use IPv6 for tsung internal communications -h Show usage BUGS
