Description
Hi, I got this error on some batches when training mesh decoder.
RuntimeError: /io/build/temp.linux-x86_64-cpython-310/spconv/build/core_cc/src/cumm/conv/main/ConvMainUnitTest/ConvMainUnitTest_matmul_split_Simt_f32f32f32_0.cu(222)
int64_t(N) * int64_t(C) * tv::bit_size(algo_desp.dtype_a) / 8 < int_max assert faild. your data exceed int32 range. this will be fixed in cumm + nvrtc (spconv 2.2/2.3).

Research direction
Start by reproducing mesh decoder training with the batches that trigger the reported spconv assertion. Inspect the referenced ConvMainUnitTest_matmul_split_Simt_f32f32f32_0.cu assertion and the spconv/cumm version behavior around the int32 range limit. Done means affected batches train without the overflow error, but the issue does not identify a source file or reproduction data.
