JIRA ID: ALMIOPEN-3158

Motivation

Follow-up to #14905 (ROCM-23567). The stale /// \todo 40.0f is too much. The solver needs to be checked. in unit_conv_solver_ConvHipImplicitGemmV4R1WrW.cpp implied a possible solver defect.

Technical Details

Replaces the stale todo with a comment stating the tolerance reflects FP32 accumulation order over K = NHoWo = 193600 with zero-mean random data, not a solver defect. Comment-only; no functional change.

Risk Assessment

Risk Level: 🟢 Low

Comment-only change.

Test Plan

Investigation runs on gfx90a (MI210): measure rms relative error vs the GPU reference (accumulates in double) for N=8/16/32/64, with random data and with small-integer data. Nothing to build since the change is comment-only.

Test Result

• Random data, rms relative error grows with K: N=8: 2.4 eps, N=16: 4.5, N=32: 11.6, N=64: 30.1 eps (deterministic). The N=64 value 3.59e-06 matches the gfx1030 result.
• Small-integer inputs (exactly representable in FP32): N=8/16/32/64 give exactly zero error at default tolerance, so the kernel computes the correct sum.
