Unable to create GPU accelerators

Anonymous26 — Tue, 01 Jul 2014 12:01:07 GMT

Hello

I am using the February Preview of IPP Asynchronous Libraries for C/C++. I have been working on a project which requires me to create a single accelerator from a file and use it over multiple files. CPU accelerator created in this manner is being used over the files without any problem and generating the expected results. However, when I direct the program to create a GPU accelerator, it still creates a CPU accelerator.

The examples provided with the Feb release are successfully creating a GPU accelerator (HPP_ACCEL_TYPE_GPU_VIA_DX9) when directed, hence the system specifications and drivers are in place.

Is it because I am writing the code on one machine and using the generated dlls for running a program on another machine?

Both the machines have the IPP February release installed, but only one(destination machine) has the hardware specifications capable of GPU acceleration. I am writing the code on another(source) machine, building it, and transferring the dlls generated to the destination machine.

Thanks.

Hello

Update: The problem seems to be that operating through .dll, the machine cannot generate GPU accelerators and hence proceeds with CPU acceleration. Hence, is their a way to produce GPU acceleration through .dll as happens with .exe?

Hello

Update: GPU acceleration through .dlls can be obtained by copying the runtime dlls from the IPP-A installation directory to the directory containing the generated dlls.

Thanks to Dmitry from Intel for suggesting this.

Thanks.
