RunCL is a command-line tool to build, execute, and debug OpenCL programs, with a simple, easy-to-use interface.
Usage: runcl [platform-options] [-I<include-dir>] [[-D<name>=<value>] ...]
<kernel.[cl|elf]> [kernel-arguments]
<arguments> <num_work_items>[/<work_group_size>]
[platform-options]
-v verbose
-gpu use GPU device (default)
-cpu use CPU device
-device <name>|#<num> use specified device
-bo <string> OpenCL build option
[kernel-options]
-k <kernel-name> kernel name
-p use persistence flag
-r[link] <exec-count> execution count
-w <msec> waiting time
-dumpcl dump OpenCL code after pre-processing
-dumpilisa dump ISA of kernel and show ISA statistics
-dumpelf dump ELF binary
The <arguments> shall be given in the order as required by the kernel.
For value arguments use
iv#<int/float>[,<int/float>...] or
iv:<file> (e.g., iv#10.2,10,0x10)
For local memory use
lm#<local-memory-size> (e.g., lm#8192)
For input buffer use
if[#<buffer-size>]:[<file>][#[[<checksum>][/<file>[@<offset>#<end>]]]]
(e.g., if:input.bin)
For output (or RW) buffer
of[#<buffer-size>]:[#]<file>[@<ofile>][#[[<checksum>][/[+<float-tolerance>]<file>[@<offset>#<end>]]]]
(e.g., of#16384:output.bin)
For input image use
ii#<width>x<height>,<stride>,<u8/s16/u16/bgra/rgba/argb>:<file>
(e.g., ii#1920x1080,7680,bgra:screen1920x1080.rgb)
For output image use
oi#<width>x<height>,<stride>,<u8/s16/u16/bgra/rgba/argb>:<file>
(e.g., oi#1920x1080,7680,bgra:screen1920x1080.rgb
