There is no guarantee that by the time core #0 is done, all the > other cores are done too, which can explain why you see garbage results. > > Even worse - I just noticed that you "poll" on an uninitialized data! core_done contains garbage the first time you go into the while() test. Thus it never really reads the result buffer. You should assign 0's to the core_done array before going into the while() loop. Note that the reason you have garbage there, as opposed to the device side structure, is that in the host side you declared "result" as an automatic, local variable - which is not initialized. -- =========================================================== Yaniv Sapir Adapteva Inc. 1666 Massachusetts Ave, Suite 14 Lexington, MA 02420 Phone: (781)-328-0513 (x104) Email: yaniv@...pteva.com Web: www.adapteva.com ============================================================ CONFIDENTIALITY NOTICE: This e-mail may contain information that is confidential and proprietary to Adapteva, and Adapteva hereby designates the information in this e-mail as confidential.
