Hi Roland, Hi Erik,
Thanks again for your email, these are very helpful. I found my mistake: previously we(me and my colleague at Notre Dame) had installed the Debian version of visit 3.1.0(134a7fd ) on our RHEL cluster. So we reinstalled the RHEL version from ( https://wci.llnl.gov/simulation/computer-codes/visit/executables) now. So now, when I open VisIt, I do get CarpetHDF5 as a supported extension. CarpetHDF5 is also enabled in "Options/Plugin Manager" menu. And my VisIt GUI looks like the screenshot from Rolandlast email. But now I get a new error, when I try to load rho.xy.h5 directly on the VisIt GUI: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Error opening plugin file: ... /visit/3.1.0/3.1.0/linux-x86_64/plugins/databases/libMADIOS2Database.so (libfabric.so.1: cannot open shared object file: No such file or directory) - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Along with the RHEL version we also tried Fedora and CentOS just because they are related, but getting the same error. I think this error of "libfabric.so" missing is because the VisIt files from here (https://wci.llnl.gov/simulation/computer-codes/visit/executables) are pre-compiled on Intel machines, and our cluster is a different machine. We are still trying to see if there is a workaround for "libfabric.so", or if we can compile visit directly on our machine. I currently don't have the tool "h5format_convert". I will try to get it as soon as we get the libfabric.so issue fixed. Yours sincerely, Atul.
