Alex Voicu 28f87f7d2e This switches HIP from its currently convoluted macro + pfe based dispatch mechanism to a more natural one partially based on the existing module API. The basic idea is that HCC will always correctly emit __global__ functions: as empty-bodied stubs, on host, and as kernels, on device. It then becomes trivial to obtain the mangled name on host, at dispatch, from the function's address, and then to use the mangled name to retrieve the kernel. This should address all problems stemming from serialisation, dubious mismatches due to the manufactured functor, macro-isms et al. It also immediately enables support for generalised globals as a consequence of that being available in the module API. Finally, it will make debug much easier, since the actual names of the __global__ functions will automatically be used in traces etc. One detail is that due to how dispatch works now (hipLaunchKernel and hipLaunchKernelGGL are themselves variadic function templates which deduce the function type of the callee), in certain cases it may be necesssary to insert explicit casts to ensure that the variadic argument list selects a viable overload - this can be observed in some unit tests. Eventually we may be able to remove this limitation, but for now it does not appear terribly onerous. The code is not extremely HIPpie, nor is it fully optimised, but rather is intended as a starting point for the HIP team to make its own. 2017-11-01 15:09:59 +00:00

Ben Sander 92bd54d7b3 Expand test to cover copy followed by event sync 2017-05-23 23:15:45 -05:00
Ben Sander ff9bed6535 hipHostMalloc allocation are mapped to all devices by default. 
Support hipHostMallocPortable flag.
Default flags are hipHostMallocPortable | hipHostMallocMapped.

Also:
-refactor tests to move addCount and addCountReverse into HipTest
namespace.
-test multi-GPU host memory.

Ben Sander ae9fdf9bc1 Fix hipStreamWaitEvent for single GPU. 2017-05-10 13:23:49 -05:00
Ben Sander 444e4a20ba Update streamEventTEst. 
- add checks for events across devices.
- refactor test to make sure it runs long enough to sensitive sync
  techniques.
- add tests for DeviceSync, streamWaitEvent.

wsttiger a10d37e5e6 Improve hipStreamWaitEvent test. 
- use addOne kernel, use local initializer rather than init_array.
- use addOneReverse test to add from back of array.  Test alternate fwd and backward to stress dependency logic.
- check device-side dependencies.
