I've used the intel compilers on various clusters, always with qt
disabled. it's always been fast enough that I've not given it a
second thought. Have you watched top during the build? This may give
some insight.<br>

<p>Last time I used icc (two years ago) I vaguely recall that
compile time was slower but it couldn't have been that much
slower. I would have remembered that. The paraview-manta render

result was a percent or two faster. This was on an intel based
linux cluster.</p>

No, I was not on the Lustre filesystem. Regardless, I moved
everything to<br>
my home directory. This did not help the speed issue much.<br>
<br>
Removing the kernel module did reduce the dependency problems
somewhat,<br>
but not completely.<br>
<br>
<br>
FYI, the essence of my build script follows:<br>
<br>
cmake ../ParaView-3.14.1-Source \<br>
-DCMAKE_C_COMPILER=icc -DCMAKE_CXX_COMPILER=icpc \<br>
-DCMAKE_Fortran_COMPILER=ifort \<br>
-DCMAKE_INSTALL_PREFIX:PATH=$HOME/PARAVIEW \<br>
-DHDF5_INCLUDE_DIR=$HOME/HDF5/include \<br>
-DHDF5_LIBRARY=$HOME/HDF5/lib/libhdf5.so \<br>
-DPARAVIEW_ENABLE_PYTHON=ON<br>
make -j 4<br>
make install<br>
<br>
However, after a bit of experimentation, I see that when I
remove the line<br>
<br>
-DCMAKE_C_COMPILER=icc -DCMAKE_CXX_COMPILER=icpc<br>
<br>
i.e., when I use the gnu compilers, the build seems to proceed
at a rate<br>
that indicates a total build time of maybe 30 minutes or so.<br>
<br>
<br>
So, the question is, are you aware of any problems with using
the intel<br>
compilers to build paraview??? Thanks.<br>
<br>
<br>
Cheers,<br>
