This is an old machine. Celeron(R) CPU G1820@2.7GHz and Intel HD Graphics.
After I tweaked gpuarray context.rs to use the CPU it converges as normal. and the first 999 epoch reachs over 70%

I think I reproduce the culprit. I find the gnuabi opencl.lib compiles with msvc abi. AND in that situation, the mnist doesn't converge at all. because the the msvc binary compiled with gnu abi generated opencl.lib
That's extreme weird. While GNU abi won't compile the msvc abi generated lib. The issue is msvc abi shouldn't compile with gnu generated lib silently.
on a low end GPU, the code doesn't converge, and the first 999 epoch is only around 10%.
