Occasional ContributorMemory read stall rate
In my openCl code when ever I am reading something from global memory I am getting stall rate of around 30%. I am using float16 to read 16 continuous memory location. Can anyone suggest me way to re...

Frequent ContributorOne float16 access per external memory DIMM in a kernel running at at an operating frequency equal to or higher than the memory controller operating frequncy (200 MHz on Stratix V and 266 MHz on Arria 10) will exhaust the external memory bandwidth and result in memory stalls. This is expected behavior and will not necessary reduce performance since the kernel is already running at its peak achievable throughput.
