Altera OpenCL parallel execution in FPGA -

i have been looking altera opencl little while, improve heavy computation programs moving computation part fpga. managed execute vector addition example provided altera , seems work fine. i've looked @ documentations altera opencl , came know opencl uses pipelined parallelism improve performance.

i wondering if possible achieve parallel execution similar multiple processes in vhdl executing in parallel using altera opencl in fpga. launching multiple kernels in 1 device can execute in parallel? possible? how check if supported? appreciated.

thanks!

the quick answer yes.

according altera opencl guides, there 2 ways achieve this:

1/ simd vectorised data load/store

2/ replicate compute resources on device

for 1/, use num_simd_work_items , reqd_work_group_size kernel attributes, multiple work-items same work-group run @ same time

for 2/, use num_compute_units kernel attribute, multiple work-groups run @ same time

please develop single work-item kernel first, use 1/ improve kernel performance, 2/ considered @ last.

by doing 1/ , 2/, there multiple work-groups, each multiple work-items running @ same time on fpga device.

note: depending on nature of problem solving, may above optimization may not suitable.
