Marco de Abreu reassigned MXNET-99:
-----------------------------------
Assignee: Marco de Abreu
> P3 (Nvidia V100) not supported by CUDA8
> ---------------------------------------
>
> Key: MXNET-99
> URL: https://issues.apache.org/jira/browse/MXNET-99
> Project: Apache MXNet
> Issue Type: Bug
> Reporter: Marco de Abreu
> Assignee: Marco de Abreu
> Priority: Major
>
> During my tests to upgrade our CI for [Quantization
> support|[https://github.com/apache/incubator-mxnet/pull/9552],] I have
> noticed that NVCC supplied with CUDA 8 does not support the GPU architecture
> 7.0, which represents Volta GPUs used in AWS P3 instances. Our Makefile
> automatically removes this architecture in
> [https://github.com/apache/incubator-mxnet/blob/master/Makefile#L280,] which
> is fine since it would crash otherwise.
>
> This causes pre-compilation to generate incompatible PTX binaries and thus
> causing issues during runtime - the JIT compiler has to kick in and libraries
> like CuBLAS report CUBLAS_STATUS_ARCH_MISMATCH.
