[gem5-users] Synchronization mechanisms not working in SE mode?

Hi all, I am having trouble with gem5 SE mode running a simple memory copy microbenchmark (https://github.com/BTone/cagbench) that uses a configurable number of worker threads that all wait to start and finish at a barrier. I have found that using a pthread_barrier is not working, as once all

[gem5-users] Performance tanking with memory intensive benchmark compared to real machine

Hello, I am running a simple single threaded memory benchmark that measures the time it takes to copy an array (https://github.com/BTone/cagbench). I run the benchmark in SE mode with only 1 thread (and 1 CPU) configured to match the setup used in gem5-Skylake (

[gem5-users] Express snooping packet being queued during multi-threaded execution in SE mode?

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

[gem5-users] Adding Delays to Non-Memory Objects?
