[AMD Public Use] Hi Yichen,
Based on the changes I see you've made, it seems like you are using an older version of gem5. These should all be fixed, including the error you are seeing, on the tip of develop. Keep in mind GCN3 was not officially part of the gem5 20.1 release, so the most up to date version is on the develop branch until the next gem5 release. -Matt From: Yichen Yang via gem5-users <gem5-users@gem5.org> Sent: Friday, November 6, 2020 11:34 AM To: gem5-users@gem5.org Cc: Yichen Yang <yang...@umich.edu> Subject: [gem5-users] gem5 GCN3 GPU model running issues [CAUTION: External Email] Hi, I was trying to run gem5 with its GCN3 GPU model following the instructions on https://www.gem5.org/documentation/general_docs/gpu_models/GCN3<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.gem5.org%2Fdocumentation%2Fgeneral_docs%2Fgpu_models%2FGCN3&data=04%7C01%7Cmatthew.poremba%40amd.com%7C0142b05660bf49b3b16f08d8828b3bf3%7C3dd8961fe4884e608e11a82d994e183d%7C0%7C0%7C637402881812060462%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=vG01%2FQpQFyGqwnDvZrc1U%2FsX2rpxM2oE5PMdwJPeER0%3D&reserved=0>. I fixed some bugs in the code but still cannot run the example. I attached commands and bugs I fixed below. The simulator launched and running into this problem: Program Started! info: running on device info: architecture on AMD GPU device is: 801 info: allocate host mem ( 7.63 MB) info: launch 'vector_square' kernel panic: panic condition availableTokens > maxTokens occurred: More tokens available than the maximum after recvTokens!
