How keep running a program n an another computer via a connection ssh when the connection is closed?

Hi everybody,

I am running a program on a supercomputer via my personal computer through a ssh connection. My program take more than a day to run, so when I left work with my PC I stop the connection with the supercomputer and the program stop.

I am wondering if someone know how I can manage to keep my program running on the supercomputer even if the connection with my computer is closed?

Thancks in advance!
Cheers Thomas

SCP(1)							    BSD General Commands Manual 						    SCP(1)

NAME
scp -- secure copy (remote file copy program) SYNOPSIS
scp [-pqrvBC46] [-F ssh_config] [-S program] [-P port] [-c cipher] [-i identity_file] [-o ssh_option] [[user@]host1:]file1 [...] [[user@]host2:]file2 DESCRIPTION
scp copies files between hosts on a network. It uses ssh(1) for data transfer, and uses the same authentication and provides the same secu- rity as ssh(1). Unlike rcp(1), scp will ask for passwords or passphrases if they are needed for authentication. Any file name may contain a host and user specification to indicate that the file is to be copied to/from that host. Copies between two remote hosts are permitted. The options are as follows: -c cipher Selects the cipher to use for encrypting the data transfer. This option is directly passed to ssh(1). -i identity_file Selects the file from which the identity (private key) for RSA authentication is read. This option is directly passed to ssh(1). -p Preserves modification times, access times, and modes from the original file. -r Recursively copy entire directories. -v Verbose mode. Causes scp and ssh(1) to print debugging messages about their progress. This is helpful in debugging connection, authentication, and configuration problems. -B Selects batch mode (prevents asking for passwords or passphrases). -q Disables the progress meter. -C Compression enable. Passes the -C flag to ssh(1) to enable compression. -F ssh_config Specifies an alternative per-user configuration file for ssh. This option is directly passed to ssh(1). -P port Specifies the port to connect to on the remote host. Note that this option is written with a capital 'P', because -p is already reserved for preserving the times and modes of the file in rcp(1). -S program Name of program to use for the encrypted connection. The program must understand ssh(1) options. -o ssh_option Can be used to pass options to ssh in the format used in ssh_config(5). This is useful for specifying options for which there is no separate scp command-line flag. For example, forcing the use of protocol version 1 is specified using scp -oProtocol=1. -4 Forces scp to use IPv4 addresses only. -6 Forces scp to use IPv6 addresses only. DIAGNOSTICS
scp exits with 0 on success or >0 if an error occurred. AUTHORS
Timo Rinne <tri@iki.fi> and Tatu Ylonen <ylo@cs.hut.fi> HISTORY
