[Public] Hi David,
You are hitting the limit on the number of same MachineTypes in a Ruby network. You can change this by modifying the `build_opts/GCN_X86` file and adding a new line with `NUMBER_BITS_PER_SET = '128'`, or higher, and then recompile gem5. As far as I know there is not a limit on the number of CUs. -Matt From: David Fong via gem5-users <gem5-users@gem5.org> Sent: Tuesday, March 8, 2022 3:51 PM To: David Fong via gem5-users <gem5-users@gem5.org> Cc: David Fong <da...@chronostech.com> Subject: [gem5-users] gem5 : X86 + APU (gfx801) with CUs128 error with DNNMark test_fwd_softmax [CAUTION: External Email] Hi, I built gem5 with X86 and APU (gfx801) with CUS=128 to run DNNMark test_fwd_softmax showing steps below and message outputs from the run Is there a limitation on number of CUs (compute units) for the APU (gfx801) or do I need to add the number of compute units (128) on one of the cmd-lines below ?
