OpenCL: increase maximum number of pipe arguments
I have a design composed of several kernels communicated via pipes.
One of my kernels has more than 20 pipes, but the limitation on a Intel i5 CPU seems to be 16:
# clinfo | grep pipe
Max number of pipe args 16
Max active pipe reservations 65535
Max pipe packet size 1024
Question: is there any way to increase number of pipes args?
Any help would be appreciated!

I'd do this: Producer writes data pipe, also saves indexes (20 of them) into command pipe. Consumer reads command pipe, extracts 20 id values and does 20 x reads on data pipe. If all 20 datas can fit into single packet, why not make 1 struct to hold all data? Are those pipes completely decoupled from each other or have different number of reads/writes? Maybe you can achieve same thing using a "any" type design to hold any data type at a time but not all and do 20x reads/writes again. Maybe having an extra "type" field in struct and a float, int, userDefined1, userDefined20, .. near that field.

struct myType { int typeId; float data1; int data2; float4 data20; }but I don't know if type based code branching and using a big struct is slower or faster.

@Matthieu its not what L30nardo SV. asks. Just a workaround.

@huseyintugrulbuyukisik too bad, because it looks good (at least better than "buy a new CPU" ;))

No, and yes.
No, because this is a descriptive information related to your hardware.
That line is the output of the following code:
{ CLINFO_BOTH, DINFO(CL_DEVICE_MAX_PIPE_ARGS, "Max number of pipe args", int), dev_is_20 },
CL_DEVICE_MAX_PIPE_ARGS seams to be a new feature of opencl 2.0 New in version 2015.2.
This is the same like how many cores you have.
If you have only 2 cpu cores you hardly using 8.
Yes, because there is a way to increase number of pipes args.
You Have to buy an other CPU one which supports more arguments.
My answer is probably disappointing.
Sorry
Good luck with your project.
