Re: [m5-dev] possible contributions to M5
2. SIMD cores: Based on TimingSimpleCPU. This sounds pretty interesting too. Does the ISA matter much, or do you think it could be pretty generic? Did you add new instructions to do things? Yes, I amended the Alpha ISA and added two instructions to mark the begin and end of branch divergences. I assume we can do the same thing for other ISAs. 3. A parallel API for writing parallel benchmarks that run in system emulation mode. So, this doesn't depend on #2? I assume that this is in syscall emulation mode? This is pretty interesting. The one issue is that there are already two? systems in m5 for doing parallel simulations and we don't want to just throw the kitchen sink into m5. Have you looked at the current m5threads stuff? Is there any overlap? No it doesn't. Actually, #2 depends on this one. Yes, it's in syscall emulation mode. Thanks for the pointer, I'll take a look at m5threads. 4. A batch-simulation tool, which creates, manages, organizes, and analyzes simulation tasks in batches. Written in Python. Good for space exploration and sensitivity study. Sure, I will write some documentation and send you a tarball. Thanks, Jiayuan ___ m5-dev mailing list m5-dev@m5sim.org http://m5sim.org/mailman/listinfo/m5-dev
Re: [m5-dev] possible contributions to M5
1. An in-order CPU module with multi-threading (switching threads upon cache accesses) based on TimingSimpleCPU This is probably #1 on the priority list Is this inorder model detailed (in terms of pipeline stages, branch prediciton, Functional Units, etc.)? No it's not detailed (so I guess it does not antiquate the actual inorderCPU model that you are developing). It's simply have multiple active thread contexts on a TimingSimpleCPU and the CPU switches among them upon memory accesses. Is it functional within Full system mode? I've only used it for system emulation mode. If your team is interested and can help me with fully system mode, I am willing to bring it to full system mode afterwards.

Re: [m5-dev] possible contributions to M5
Hi Steve, Personally I would say 2,3,4,1... but I can understand how others might have different priorities. (Actually I haven't seen two people with the same order yet!) Maybe I should first re-take Stats101 to measure the best average of the ordering :) I think a key question that Nate already hinted at is how related are items 1-3... I can see #1 being somewhat independent, but it sounds like #2 #3 might be interdependent? Do they also depend on #1? Yes, #2 depends on #3. #1 is standalone. All of them are only tested in system emulation mode. Thanks, Jiayuan ___ m5-dev mailing list m5-dev@m5sim.org http://m5sim.org/mailman/listinfo/m5-dev
[m5-dev] possible contributions to M5
Dear M5 Team, I'll soon start to work on integrating our M5-based simulator, MV5, into M5. I've read some documentation on the current status of M5, and I'd like to share my plan/ideas with you and hear your suggestions. Since M5 will soon replace its entire memory system modeling with RubyGems, it seems the interconnect and directory coherence modules in MV5 will have little value for future M5. I'm wondering if the following contributions would be interesting to you. 1. An in-order CPU module with multi-threading (switching threads upon cache accesses) based on TimingSimpleCPU. 2. SIMD cores: Based on TimingSimpleCPU. It models GPU-like branch handling using the re-convergence stack. It is implemented as an array of scalar threads rather than wider vector registers. It requires a parallel API written in a similar style to OpenMP, with manually instrumentation to signal the end of a branch in the parallel section of code. 3. A parallel API for writing parallel benchmarks that run in system emulation mode. It can be used in a similar way to Pthread. It also provide OpenMP-like programming interface, and it can work with the SIMD cores. It also comes with various scheduling policies. 4. A batch-simulation tool, which creates, manages, organizes, and analyzes simulation tasks in batches. Written in Python. Good for space exploration and sensitivity study. I manage tens of thousands of simulations over up to 100 machines using this tool. It can work with a cluster of machines with a shared file system. It also supports the PBS queuing system. What do you think about the above contributions? Can you prioritize them? Thanks, Jiayuan ___ m5-dev mailing list m5-dev@m5sim.org http://m5sim.org/mailman/listinfo/m5-dev
Re: [m5-dev] Any interest in directory coherence based on Jiayuan's Patch
Dear all, Just curious --- Is anyone going to ICS or coming around New York around June 10 or 11th? If so, we can meet and talk :) I know it's been a long struggle --- we have made a couple attempts in the past to get the patches into M5's source tree, but we didn't make much progress and I think the main reason is we need time to communicate and digest the patches before they can be integrated. I fully respect the work of Gems and Ruby and it would be great to combine them with M5. In the meantime, I think the patches offer good alternatives and can become a integral tool for the M5 user community. They are designed, programmed and used in an M5 style and philosophy, and they have been tested by various users and now support full-system simulation with Parsec (Lots of thanks to Rick!). I am open to sit down for a week or two focusing on the integration, and I think two weeks would be sufficient for coding and initial testings. To re-kick off the ball and move on, I can make slides to show the structure/design of the patches, send them to you for feedback, and then we can arrange some time to discuss more details. Would you be interested to resume the process?

I have a mesh2D model that works well with an MSI directory coherence protocol. Both the interconnection and directory coherence models are extendable. Another patch is to support multithreading for simple CPUs. The cpu can switch to another HW thread context if it has a data access. However, atomic modes are not well tested. And I haven't considered checkpoints. The mercurial patches are based on changeset 5291:456a50cf2a67, a version after 2.0beta4 but before 2.0beta5. As an external developer, how do you think I should submit the patches? An do you think it would be necessary to update the patches so they are based on a more recent changeset? If so, which changeset? Just hope it might be useful. Thanks! Jiayuan Meng Need to know now? Get instant answers with Windows Live Messenger.

Re: [m5-dev] submit patches: Mesh2D, directory coherence, and multithreading
Thanks! Yeah, I used mercurial queue to manage the patches. Ali and Steve helped me with that. I'll see if I can pull out the most recent version, and please give me some time to update the patch for the new changeset.

The best thing you can do is get your code working with the new repository using mercurial and mercurial queues. If you do that, then we can work with you to make sure that the code meets all of the requirements (doesn't break things, is reasonably organized, meets the style guidelines, etc.) Did you use a revision control system as you did your work?

I'm a graduate student working with Prof. Kevin Skadron at University of Virginia. And now, I'd like to submit patches to M5 that enables it to simulate CMP architecture.

Re: [m5-dev] submit patches: Mesh2D, directory coherence, and multithreading
great! Thanks for the support!

I noticed you added support for multithreading for simple CPUs. I wouldn't mind figuring out checkpoints with the multithreaded simple CPUs as it would free me from EIO trace madness. Let me know when the patches are in m5. -Rick jiayuan meng wrote: Thanks! Yeah, I used mercurial queue to manage the patches. Ali and Steve helped me with that.
