[Paraview] Building on Titan using ParaViewSuperbuild

Thu Aug 29 15:51:38 EDT 2013

So coprocessing will not be built using the below instructions? I would have mentioned that, but coprocessing appears to still be part of a regular, non-cross-compile build, so I figured it was part of ENABLE_paraview

Also, for the below configcross.sh, do we need to pass in a CMake variable telling it where the tools build dir is located?
Thanks,
Mark

Hi David,

I just started to try superbuild on Titan also. I don't see you set ENABLE_MPI to be true in your configure script. Could you confirm whether ENABLE_MPI needs to be set to TRUE in order for ParaView to run on Titan in parallel? Since my purpose is to link our

The ENABLE_MPI flag at the Superbuild level is unrelated. It has a purpose only when CROSS_BUILD_STAGE=HOST, that is when making ParaView binary installers for desktops from Superbuild.

You shouldn't turn it on in the TOOLS or CROSS stages. Instead let the CROSS stage use the system installed MPI. It does that by turning PARAVIEW_USE_MPI=ON when it configures the ParaView sub-build. See CMake/crosscompile/xk7_gnu to see where it does that, and to see the other flags it uses.

simulation code (already built statically with CMake on Titan) to ParaView CoProcessing libraries (I am using version 3.98.1) for in-situ visualization on Titan, so in this case, do I have to set ENABLE_paraview to true and do I need to enable OSMesa for ParaView to resort to off-screen rendering for in-situ visualization?

The CROSS stage turns on Python, Mesa and ParaView. Titan's accelerators don't really run X11, so Mesa is the only option for rendering there.

Although I can build ParaView from source on Titan login nodes, I am not able to run it on compute nodes, so I am starting to try superbuild hoping to be able to cross build ParaView libraries to run in-situ visualization on Titan.

I've cross compiled Catalyst itself before on a bluegene. I did it manually before SuperBuild existed. I will see if I can dig up my config scripts. Cross compiling Catalyst should be more or less that same thing as cross compiling ParaView, but a bit faster and easier because their is less code involved.

Thanks,
Hong

Your tools build is pointing to the compiler wrapper that you normally would use to make code for the back end.
The tools build should just use plain old local gcc since we only build things at that point that run on the login node.

Try these setup scripts:
I source configtools.sh to set up my environment before I build the compile tools, and configcross.sh before before I cross compile ParaView.

configtools.sh
#use my own cmake, system one is too old
setenv PATH /autofs/na4_proj/csc035/demarle/pvdev/titan/cmake-build/bin:${PATH}
#switch compiler to compile code for front end
module unload PrgEnv-pgi
module load gcc
#configure settings for to build compile tools only
cmake \
  -DCROSS_BUILD_STAGE:STRING=TOOLS -Dcross_target:STRING=xk7_gnu \
  -DCMAKE_BUILD_TYPE:STRING=Release \
  -DBUILD_TESTING:BOOL=FALSE \
  -DParaView_FROM_GIT:BOOL=OFF \
  -DENABLE_paraview:BOOL=TRUE \
  -DENABLE_boost:BOOL=TRUE \
  -DENABLE_python:BOOL=TRUE \
  -DENABLE_portfwd:BOOL=FALSE \
  ../../ParaViewSuperbuild

then make

configcross.sh
#use my own cmake, system one is too old
setenv PATH /autofs/na4_proj/csc035/demarle/pvdev/titan/cmake-build/bin:${PATH}
#switch compiler to compile code for back end
module unload PrgEnv-pgi
module unload gcc
module load PrgEnv-gnu
#not sure why module load wasn't sufficient, but ended up needing to force
#cmake to choose the right compiler
setenv CC /opt/cray/xt-asyncpe/5.17/bin/cc
setenv CXX /opt/cray/xt-asyncpe/5.17/bin/CC
#configure settings to cross compile python, (mesa - implied), and paraview
cmake \
  -DCROSS_BUILD_STAGE:STRING=CROSS -Dcross_target:STRING=xk7_gnu \
  -DCMAKE_BUILD_TYPE:STRING=Release \
  -DBUILD_TESTING:BOOL=TRUE \
  -DParaView_FROM_GIT:BOOL=OFF \
  -DENABLE_paraview:BOOL=TRUE \
  -DENABLE_python:BOOL=TRUE \
  ../../ParaViewSuperbuild

then make again

Hi, I'm trying to follow the advice on building ParaView on Titan using the ParaViewSuperbuild method from an earlier discussion in June.

When I run make in the "TOOLS" directory I get the following error:

I don't see a BUILD_SHARED that I can toggle. All of the CMAKE_SHARED_LINKER_FLAGS* vars are empty, if those are related.

Any suggestions?

Thanks,
Mark
