FrozenGene commented on issue #4747: [ThreadPool] Solve ARM BIG.LITTLE heterogeneous multicores URL: https://github.com/apache/incubator-tvm/pull/4747#issuecomment-578389093 Thanks for clarification. I will do it together in next code update.------------------ Original ------------------From: Yida Wang <[email protected]>Date: Sat,Jan 25,2020 4:44 PMTo: apache/incubator-tvm <[email protected]>Cc: Zhao Wu <[email protected]>, Author <[email protected]>Subject: Re: [apache/incubator-tvm] [ThreadPool] Solve ARM BIG.LITTLE heterogeneous multicores (#4747) To clarify your meaning, as hyper thread will make the big_count_ is twice times compared with physical cores. For example, phisical cores are 4, hyper thread will make the concurrency number be 8 (big_count_ is 8 too). So for hyper thread, we wish master thread could run the physical cores (id: 0-3), not cpu id 4-7. … ------------------ Original ------------------ From: Yida Wang <[email protected]> Date: Sat,Jan 25,2020 3:21 AM To: apache/incubator-tvm <[email protected]> Cc: Zhao Wu <[email protected]>, Author <[email protected]> Subject: Re: [apache/incubator-tvm] [ThreadPool] Solve ARM BIG.LITTLE heterogeneous multicores (#4747) FYI, we just notice that if we don't bind the master thread, which is the default behavior, the master thread may cause the contention issue as it is allocated to a seemingly idle logical thread under hyperthreading. So I would propose to at least have the master thread bound to the intended running cores by default. @anijain2305 — You are receiving this because you authored the thread.
