When I compile caffe with NCCL, there are erross: src/caffe/parallel.cpp: In instantiation of ‘void caffe::NCCL::Run(const std::vector&, const char) [with Dtype = float]’: src/caffe/parallel.cpp:372:1: required from here src/caffe/parallel.cpp:343:5: error: no matching function for call to ‘caffe::Worker::StartInternalThread()’ w->StartInternalThread(); ^ In file included from ./include/caffe/parallel.hpp:20:0, from ./include/caffe/caffe.hpp:16, from src/caffe/parallel.cpp:15: ./include/caffe/internal_thread.hpp:34:8: note: candidate: void caffe::InternalThread::StartInternalThread(caffe::device) void StartInternalThread(device device_context); ^ ./include/caffe/internal_thread.hpp:34:8: note: candidate expects 1 argument, 0 provided src/caffe/parallel.cpp: In instantiation of ‘void caffe::NCCL::Run(const std::vector&, const char) [with Dtype = double]’: src/caffe/parallel.cpp:372:1: required from here src/caffe/parallel.cpp:343:5: error: no matching function for call to ‘caffe::Worker::StartInternalThread()’ w->StartInternalThread(); ^ In file included from ./include/caffe/parallel.hpp:20:0, from ./include/caffe/caffe.hpp:16, from src/caffe/parallel.cpp:15: ./include/caffe/internal_thread.hpp:34:8: note: candidate: void caffe::InternalThread::StartInternalThread(caffe::device) void StartInternalThread(device device_context); ^ ./include/caffe/internal_thread.hpp:34:8: note: candidate expects 1 argument, 0 provided Makefile:717: recipe for target '.build_release/src/caffe/parallel.o' failed make: [.build_release/src/caffe/parallel.o] Error 1 make: Waiting for unfinished jobs.... src/caffe/layer_factory.cpp: In function ‘boost::shared_ptr<caffe::Layer > caffe::GetPoolingLayer(const caffe::LayerParameter&) [with Dtype = double]’: src/caffe/layer_factory.cpp:251:1: warning: control reaches end of non-void function [-Wreturn-type] } ^ src/caffe/layer_factory.cpp: In function ‘boost::shared_ptr<caffe::Layer > caffe::GetPoolingLayer(const caffe::LayerParameter&) [with Dtype = float]’: src/caffe/layer_factory.cpp:251:1: warning: control reaches end of non-void function [-Wreturn-type]

NCCL is currently unsupported in OpenCL Caffe. Single GPU only for both CUDA and OpenCL until a device unified solution is available.
