I was working on enabling all cores to work with different key and setting. I first tried to store key and setting in shared DRAM and read it from there. For some reason it worked only for 2 cores. Other cores couldn't retrieve correct value. I gave up that approach and stored key and setting into each core local memory. Now execution speed is a bit higher - 292.021000 ms. I have 16 calls to e_write to write key into local memory and than 16 more to write setting. Katja Content of type "text/html" skipped
