[yt-users] yt 2.0 on Kraken

[Stephen Skory]

Hi all,

I have just installed and built yt-2.0 on Kraken. The Cray CNL kernel has been 
upgraded on Kraken which means that the old static-Python build requirements are 
no longer necessary. This means that it is easier to install yt on Kraken, which 
would seem to make the common install unneeded. However, one of the requirements 
for running with shared-Python is that various shared libs need to be copied to 
lustre because the compute nodes cannot see the home disks. This install of yt 
is in a non-volatile part of lustre, so you don't have to worry about things 
being deleted from underneath you as a result of automated purges.

To use it is simple, your environment needs to be set like this (depending on 
your $SHELL):

export PYBASE=/lustre/scratch/proj/yt_common/2.0
export PATH=$PYBASE/2.0/bin:$PATH
export PYTHONPATH=$PYBASE/lib/python2.6/site-packages
export LD_LIBRARY_PATH=$PYBASE/lib:$LD_LIBRARY_PATH

when you want to run a batch job, you need to also set this (you should probably 
make the dot-dir by hand, first):

export MPLCONFIGDIR=$TG_CLUSTER_SCRATCH/.matplotlib/

Let me know if you have problems!
