Open Computing Language (OpenCL) is a framework for writing programs that execute across heterogeneous platforms consisting of central processing units (CPUs), graphics processing units (GPUs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs) and other processors or hardware accelerators. OpenCL specifies programming languages (based on C99 and C++11) for programming these devices and application programming interfaces (APIs) to control the platform and execute programs on the compute devices. OpenCL provides a standard interface for parallel computing using task- and data-based parallelism. Read more on Wikipedia...


Example from Linguist:
/* Old-style comment. */ // New-style comment. typedef float foo_t; #ifndef ZERO #define ZERO (0.0) #endif #define FOO(x) ((x) + \ ZERO) __kernel void foo(__global const foo_t * x, __local foo_t y, const uint n) { barrier(CLK_LOCAL_MEM_FENCE); if (n > 42) { *x += y; } }
Example from Wikipedia:
// This kernel computes FFT of length 1024. The 1024 length FFT is decomposed into // calls to a radix 16 function, another radix 16 function and then a radix 4 function __kernel void fft1D_1024 (__global float2 *in, __global float2 *out, __local float *sMemx, __local float *sMemy) { int tid = get_local_id(0); int blockIdx = get_group_id(0) * 1024 + tid; float2 data[16]; // starting index of data to/from global memory in = in + blockIdx; out = out + blockIdx; globalLoads(data, in, 64); // coalesced global reads fftRadix16Pass(data); // in-place radix-16 pass twiddleFactorMul(data, tid, 1024, 0); // local shuffle using local memory localShuffle(data, sMemx, sMemy, tid, (((tid & 15) * 65) + (tid >> 4))); fftRadix16Pass(data); // in-place radix-16 pass twiddleFactorMul(data, tid, 64, 4); // twiddle factor multiplication localShuffle(data, sMemx, sMemy, tid, (((tid >> 4) * 64) + (tid & 15))); // four radix-4 function calls fftRadix4Pass(data); // radix-4 function number 1 fftRadix4Pass(data + 4); // radix-4 function number 2 fftRadix4Pass(data + 8); // radix-4 function number 3 fftRadix4Pass(data + 12); // radix-4 function number 4 // coalesced global writes globalStores(data, out, 64); }
