Seismic Unix and spl

Seismic unix and spl (containing finite-difference seismic modeling and migration) must be set up before use. To set up the necessary environment variables copy the following text to the file ".profile" in your home directory

#---- SU 
CWPROOT=/arkiv/arkiv1/barn/sim/src/su
export CWPROOT
PATH=$CWPROOT/bin:$PATH

#--- MPI
PATH=/arkiv/arkiv1/barn/sim/src/mpich-64/bin:$PATH

#--- SPL
SYS=x86_64
export SYS
SPL=/arkiv/arkiv1/barn/sim/src/spl
PATH=$SPL/bin:$PATH
export SPL

To activate the profile, type

. .profile
