#Paraview connectivity how to#

Ask your system administrator if you are not sure how to launch your MPI programs. Different implementations of MPI may have different ways to launch parallel programs, but the most common way is to use the mpirun command. The server is a parallel MPI program that must be launched as a parallel job.

#Paraview connectivity serial#

The ParaView client is a serial application and is always run with the paraview command. We find it easier to simply provide a separate build for each server.įor more elaborate discussion on building with OSMesa support with different versions of Mesa, refer to ParaView And Mesa 3D. Some organizations use this to provide a single build for multiple servers, some with and some without hardware rendering. Mangled Mesa provides a mechanism to use either hardware acceleration or CPU-only rendering. Mangled Mesa is not supported with ParaView. Please be aware that OSMesa support is not the same thing as mangled Mesa (although they are often used for the same thing). Once again, once you build with OSMesa support, it will not take effect unless you launch the server with the -use-offscreen-rendering flag. After you configure and generate your makefiles, you should be ready to build with OSMesa support. After you configure again you will see a new CMake variable called OSMESA_LIBRARY. Next, change the VTK_OPENGL_HAS_OSMESA variable to ON. Now set the CMake variable OPENGL_INCLUDE_DIR to point to the Mesa include directory (the one containing the GL subdirectory), and set the OPENGL_gl_LIBRARY and OPENGL_glu_LIBRARY to the libGL and libGLU library files, respectively.

#Paraview connectivity download#

If you are not sure, you can always download your own copy from. It is difficult to tell an installation of Mesa from any other OpenGL implementation (although the existence of an osmesa.h header and a libOSMesa library is a good clue). The first step to compiling OSMesa support is to make sure that you are compiling with the Mesa 3D Graphics Library. If your cluster does not have graphics hardware, then compile ParaView with OSMesa support and use the -use-offscreen-rendering flag when launching the server. However, Mesa is strictly a CPU rendering library so, use the OSMesa solution if and only if your server hardware does not have rendering hardware. This whole problem can be circumvented by using the OSMesa library. One of the most difficult problems people face when installing a ParaView server is establishing XConnections.

#Paraview connectivity code#

A cluster built using a Linux operating system probably already has a version of Mesa installed, but otherwise you can always download the source code from. In this case, most people use the Mesa 3D Graphics Library, which is a portable, software-only implementation of the OpenGL API. There are many circumstances where you would want to compile the ParaView server on a parallel computer with no graphics hardware and thus no OpenGL implementation. You can apply the same trick to the MPI_INCLUDE_PATH to specify several include directories.Īnother problem sometimes encountered is the lack of graphics libraries. If you need to link in more than two libraries, you can specify multiple libraries in the MPI_LIBRARY variable by separating them with semicolons ( ).

If there are only two such libraries, you can add them separately in the MPI_LIBRARY and MPI_EXTRA_LIBRARY CMake variables. One problem many people face when compiling with MPI is that their MPI implementation provides multiple libraries, many of which are required when compiling ParaView. When following these instructions, be sure to compile in MPI support by setting the PARAVIEW_USE_MPI CMake flag to ON and setting the appropriate paths to the MPI include directory and libraries. Thus, if you wish to use ParaView on a parallel server, you will have to compile ParaView from source.Īfter downloading ParaView, follow the Building and Installation instructions.

Unfortunately, the large variety of hardware, operating systems, and MPI implementations makes this task impossible. Ideally, we would like to provide precompiled binaries of ParaView for all of our users to make installing it more convenient.
