<DIV></DIV>Hi, Ron --
<DIV>The 'floating point exception' usually means the architecture of the
executable is incompatible with the OS. Our binary releases are not 100%
statically linked, there are some shared dependencies. From your message, it's
not clear which binary release you're using -- CentOS (previously known as
RHEL) 4 or 5 (the two 64-bit builds) or i686 (the 32-bit build). Try using the
'ldd' command print out shared library dependencies and see if those libs
exist on your system, and you can compare the ldd ouptut from 2.0.a5 and later
builds. For example, the latest CentOS5 build has this: </DIV>
<DIV><BR></DIV>
<DIV>
<DIV>> ldd /usr/local/grads/2.0/2.0.a9.release/grads </DIV>
<DIV> libX11.so.6 => /usr/lib64/libX11.so.6

<DIV> libpthread.so.0 =>

<DIV>If your unix flavor is not quite the same as the OS on which the binary
was originally compiled/linked, then you may have to rebuild from source. It's
hard to say what what may have changed between a5 and a6 -- maybe our OS was
upgraded during that time. </DIV>
