It works on a single node, but for two nodes I get the following error:</P> <P><STRONG>[0] Intel(R) Trace Collector WARNING: STF Encoding Error: reducing unsigned 4-byte 0x10068 to unsigned 2-byte (_build/build_release_posix-x86_64_icl_18_gnutools_4.8/stf/stfencode.c:1844)</STRONG></P> <P>When we run the Trace Analyzer on the resulting stf file, it just hangs.
