[dpdk-dev] Queries related to Hyperthreading

[Ravi Kumar Iyer <Ravi.Iyer@aricent.com>]

hello Intel Gurus,

I have some queries related to intel HT technology. I am running an intel dpdk application and  trying to benchmark as well as optimize the same. As of now it is a single threaded application and would like to keep it like that for now. I am running it on an intel sandy bridge arch processor with HT on. Now to increase the performance I have disabled HT, but am still getting the same performance[ just a marginal improvement]. Now as per our understanding so far wrt HT, two Hardware threads share the same physical core. Now if we switch off HT[from bios] shouldn't just one hardware Thread get hold of the complete CPU core.  The application is heavily compute oriented and as such minimal memory access or any IO operations. Appreciate any insight on this.


thanks
ravi
