[gem5-users] cache bank contention

2018-04-10 Thread Timon Evenblij
Hi all, I have some questions regarding how gem5 models cache banks. In fact, I cannot find that gem5 models cache banks at all. Is this true? Why this is important: It looks as of right now that gem5 caches can process all requests in parallel, unless the requests go to the same cache block. Thi

Ouch... Nope, I haven't. I noticed it is linking with uClibc, instead of glibc, I couldn't find in the buildroot the way to change that. Adding the -static option for now to try it. Thanks for all the help so far. Rebuilding the image and will test it again in a few minutes. -Original

I think you would have to recompile your LLVM cross compiler to point to the right libc, but I'm not sure. If that use case is important to Micron, maybe try contacting Romain Naour and possibly getting Micron to sponsor: https://elinux.org/Buildroot:GSoC2017Ideas#Support_for_LLVM :-) On Tue, Apr

[gem5-users] What causes a large number of quiesceCycles for multi-thread applications?

2018-04-10 Thread Xin Zhan
Hi all, Recently I simulated 4-core alpha running Parsec benchmark in FS mode. And in the output stats.txt, I observed a large number of quiesceCycles for each core in ROI. I learned from the previous thread that the quiesceCycles are caused by interrupts. But I want to link the quiesceCycles with
