Description
In an hacky attempt tried to enable the device and system memory scope support for AMD MI210 GPU reverting the commit
https://github.com/oneapi-src/unified-runtime/commit/9947a817291628ad6d61e102e1d2bd783c041c19 to the https://github.com/oneapi-src/unified-runtime/commit/08b19b224c0be9cdd2073de080a3e654600007f1 but it didn't work out for 2 GPU system. The same code I run at level_zero 2GPU failed with AMD GPU at random iterations due to inconsistencies.
I was wondering is there an easy way to have consistent device and system wide atomic memory_scope ?
