ERROR: CL_INVALID_VALUE

Hi,

All of this seems to indicate that there is something wrong with the environment setup. You probably don't have the OpenMP
Refer to this thread: e2e.ti.com/.../425691
also the following wiki: processors.wiki.ti.com/.../MCSDK_HPC_3.x_Getting_Started_Guide

You probably don't have the OpenMP & CGT package installed in your target FS directory in your host (you probably have no $TARGET_ROOTDIR/usr/share/ti/examples/openmpacc/).

Best Regards,
Yordan

it is OK now

I'm glad to hear you resolved your problem. Thanks for updating the thread.

Yordan

It was because of one frightful environment variable! I changed it and it became OK. I do not know why?!! Now OpenMP examples are being executed on EVM but some have errors like:

root@k2l-evm:/home# /usr/share/ti/examples/opencl/float_compute/float_compute

This example computes y[i] = M[i] * x[i] + C on single precision floating point arrays of size 2097152
- Computation on the ARM is parallelized across the A15s using OpenMP.
- Computation on the DSP is performed by dispatching an OpenCL NDRange kernel across the compute units (C66x cores) in the compute de.

RunningBinary read function failure
terminate called after throwing an instance of 'std::length_error'

Thank you so much for your valuable replies which are very helpful and useful all the time. (But why the above example could not be executed?!)
Regards

Hi ali,

Do you have the dsp_compute.out in the directory float_compute? There are several approaches to create an OpenCL program, see here
In the example float_compute, by default without _TI_RTOS defined, it 'Create an OpenCL program from binary, with binary in a file', so the dsp_compute.out file must be provided.

Regards,
Garrett
