Development/debugging/benchmarking/cuda.txt

Block all calls:

CUDA_LAUNCH_BLOCKING=1 ./cudaapp

Select GPUs to use:

CUDA_VISIBLE_DEVICES="0,2"

Binding GPU to CPU cores:

numactl --cpunodebind=

GPU Direct:

To force cudaHostAlloc to allocate memory compatible with GPUDirect (Infiniband) under cuda 4.0.

With 4.1 it should work automatically:

CUDA_NIC_INTEROP=1

GPUDirect is not working over IOH

Compile to PTX:

nvcc --ptx hst_cuda.cu -I .. -I /opt/cuda/sdk/C/common/inc/ -I /usr/include/glib-2.0/ -I /usr/lib/glib-2.0/include/
