Official alpha release of X10/CUDA Since many X10 community members have been asking whether X10 will run on the GPU, as part of the 2.1 X10 release we are also releasing our CUDA backend. This enables fragments of X10 programs to run on CUDA-capable GPUs, allowing significant speedups. Here are some supported features:
* Write programs that run on host and GPU using a single language: X10 * Use existing X10 constructs (async, finish, etc) to represent many CUDA idioms * Utilize more than 1 GPU * Use a network of hosts, each with 0 or more GPUs * Implicitly copy data from host to GPU * Static prevention of errors due to accessing GPU memory on the host or vice versa * 3 small programs to try out in samples/CUDA * Automatic selection of blocks/threads based on particulars of hardware and kernel Currently using CUDA is only possible with the C++ backend and has only been tested on x86/x64 Linux with the latest CUDA drivers. X10 must be specially built from source to use CUDA devices. Please see the X10 2.1 CUDA page on the X10 website for instructions on how to try it out. http://x10.codehaus.org/X10+2.1+CUDA Questions and comments about X10/CUDA are welcome on the x10-users mailing list. Note that development of the CUDA release is ongoing in the svn repository. If you are a member of the community and your appetite has been whet by the CUDA support in the 2.1 release, consider going further and checking out svn. We have already strengthened the support for CUDA shared memory, and added access to the CUDA __syncthreads() construct via the X10 clock syntax. We intend to add more support for CUDA features over the coming weeks. ------------------------------------------------------------------------------ Nokia and AT&T present the 2010 Calling All Innovators-North America contest Create new apps & games for the Nokia N8 for consumers in U.S. and Canada $10 million total in prizes - $4M cash, 500 devices, nearly $6M in marketing Develop with Nokia Qt SDK, Web Runtime, or Java and Publish to Ovi Store http://p.sf.net/sfu/nokia-dev2dev _______________________________________________ X10-users mailing list X10-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/x10-users
