Hi The CUDA support is at an alpha stage and being actively developed but the samples should run.
X10 has to be built from source with -DX10RT_CUDA parameter to ant, this will assume cuda is installed on the build machine and the libraries are reachable on the path. The X10 program has to be compiled with x10cuda rather than x10c++. This adds the CUDA code generation plugin to the backend. It assumes that nvcc is installed and on the path and uses it to build .cubin files. At the moment one has to use -DYNAMIC_CALLS because otherwise the frontend will insert implicit casts that are not implemented on the GPU. Finally, at runtime, set the environment variable X10RT_ACCELS=ALL to allow the program to use every GPU in the system, or if more control is needed, e.g. X10RT_ACCELS=CUDA0,CUDA0,CUDA1 to set up two accelerator devices on the first place and one on the second. ________________________________________ From: x10-users-boun...@lists.sourceforge.net [x10-users-boun...@lists.sourceforge.net] On Behalf Of Sascha Roloff [sascha.rol...@googlemail.com] Sent: 16 June 2010 10:55 To: Mailing list for users of the X10 programming language Subject: [X10-users] CUDA support Hi, I am using X10 v2.0.4. Does anybody know how to activate or use the CUDA support within x10 programs? I can't find any information about that, neither on the x10 homepage nor on the internet. I just found the sample programs, but I don't know how to compile and to activate the CUDA compiler plugin? Can anybody help me?
