Good Afternoon.
I am running a custom benchmark in SE mode on x86 with multiple CPUs. The
benchmark can be run with a varying number of worker threads. When I run
the benchmark with only 1 thread everything works perfectly. However, once
I use at least two threads, I get the following error message below. Has
anyone experienced a similar issue?
info: Entering event queue @ 0. Starting simulation...

(further warnings will be suppressed)
