Brecht Van Lommel	8d6e5e2fee	Cycles: update build configurations to include CUDA sm_35 architecture. When using ... a compiler older than CUDA 5.0 it will give a warning and skip this architecture.	2013-06-20 13:10:47 +00:00
Brecht Van Lommel	16204bd647	Cycles: prepare to make CUDA 5.0 the official version we use ... * Add CUDA compiler version detection to cmake/scons/runtime * Remove noinline in kernel_shader.h and reenable --use_fast_math if CUDA 5.x is used, these were workarounds for CUDA 4.2 bugs * Change max number of registers to 32 for sm 2.x (based on performance tests from Martijn Berger and confirmed here), and also for NVidia OpenCL. Overall it seems that with these changes and the latest CUDA 5.0 download, that performance is as good as or better than the 2.67b release with the scenes and graphics cards I tested.	2013-06-19 17:54:23 +00:00
Bastien Montagne	ab2c273b12	Added GPL header to sconscripts! ... Also changed shebang to '#!/usr/bin/env python', this is more portable across unixes...	2012-12-17 08:01:43 +00:00
Brecht Van Lommel	dbd44e3bf5	Fix scons not installing closure/ directory for runtime compiles of CUDA kernel.	2012-12-03 16:51:05 +00:00
Thomas Dinges	d3c6c6babd	Cycles / CUDA: ... * Remove -use_fast_math flag from scons as well.	2012-05-28 19:49:26 +00:00
Thomas Dinges	7c630aac80	Scons/CUDA ... * Added missing bitness info to the nvcc_flags. This makes sure that the nvcc compiler builds the correct cubins.	2011-12-08 19:16:43 +00:00
Thomas Dinges	b7649ea757	Cycles / CUDA Kernel compile: ... * Added option "WITH_BF_CYCLES_CUDA_THREADED_COMPILE" for the people who have much RAM (8 or more) and can compile several kernels at the same time. If enabled, it uses the general BF_NUMJOBS flag. * The option is off per default.	2011-12-06 16:00:57 +00:00
Brecht Van Lommel	cd1e78f1b7	Cycles: scons cuda kernel compile now does one kernel at a time, to reduce memory ... usage.	2011-12-06 12:29:54 +00:00
Brecht Van Lommel	45de380771	Cycles ... * Compile all of cycles with -ffast-math again * Add scons compilation of cuda binaries, tested on mac/linux. * Add UI option for supported/experimental features, to make it more clear what is supported, opencl/subdivision is experimental. * Remove cycles xml exporter, was just for testing.	2011-12-01 16:33:21 +00:00
