Re: Problems with interrupting LDM/STM Cortex M4?

Interrupt handler does not modify r4-r11. r7 has not been modified by the exception handler.

Re: Problems with interrupting LDM/STM Cortex M4?

It's may be an idiot response but, an assembler code generated with GCC can indeed present complexities due to many non- necessary instructions. This is by no means a problem related to the processor....

CPU to GPU Copying Speed tuning.

Hi, Is there any way to speed the data copying from CPU buffers which are allocated using "malloc" to GPU accessible memory. currently I am using simple memcpy for copying data. Thanks &...

Re: How to run some etcpack.exe processes at the same time

Hi katatunix, This is something we are aware of.  The latest version of TCT stores the temporary files in the execution directory rather than the temp directory and so as long as the two processes are...

Re: CPU to GPU Copying Speed tuning.

Hi narendrakumar_chepuri, It is much faster to share buffers between CPU and GPU by allocating memory using clCreateBuffer() rather than malloc() as it can then be accessed natively by both without the...

For extra points, write a wrapper executable that invokes the real one with randomized temp directories!

Re: GPU empty Kernel overhead

Hi Narendra, Just FYI, the EnqueueNDRangeKernel entry point does not block until the end of kernel execution, it is an asynchronous call which enqueues the kernel to be executed and then returns....

Re: GPU empty Kernel overhead

Hi Chris.          I will agree with your statement but I am measuring time with start time before EnqueueNDRangeKernel and end time is after cl_flush and cl_finish which are blocking calls and...

Re: GPU empty Kernel overhead

Hi Narendra,I would agree with Michael's suggestion here of getting us a small reproducer.  Can you put a minimum example together that exhibits this issue?  It would likely be the most efficient way...
