Welcome to the RHMC-on-GPU wiki! (under development)
The typical compilation follows the pattern:
./configure && make
this will compile a code to run in a single core CPU.
In order to enable CUDA routines type the following command (also look at the
variour options in configure --help)
./configure --enable-cuda=ARCH
where ARCH should be substituted by one of the following strings "sm_XX" in order to choose the target NVIDIA architecture
- sm_10 ISA_1, Basic features
- sm_11 atomic memory operations on global memory
- sm_12 atomic memory operations on shared memory, vote instructions
- sm_13 double precision floating point support (Tesla Cards)
- sm_20 Fermi architecture support
please refer to the original NVIDIA documentation for more details on which cards support the several architectures.
Some newer compilers, like GNU gcc 4.5, are incompatible with the NVIDIA nvcc
compiler (CUDA 4.0). In order to solve this problem you should install a different
version of the compiler, e.g. gcc 4.4, in the directory PATH_TO_COMPILER and then
configure with the following command
./configure --enable-cuda=ARCH --with-cuda_comp=PATH_TO_COMPILER CXX=PATH_TO_COMPILER/g++ CC=PATH_TO_COMPILER/gcc
Also, if the mandatory library MPFR (Multiple Precision) is installed in a
non standard location (not /usr/lib) use the flag --with-mpfr=PATH where PATH is the location
of the library in your system
