dtrnlsp Example RCIRequest Flag Question

panfang — Tue, 15 Feb 2011 17:35:01 GMT

When I look at the dtrnlsp Example, I have a question about the RCIRequest Flag.

One the website http://software.intel.com/sites/products/documentation/hpc/mkl/webhelp/osr/functn_dtrnlsp_solve.html#functn_dtrnlsp_solve, It is said that "RCI_Request= 0 that indicates successful completion of the task"

Do we need to quit when RCIRequest==0 ?

Thanks a lot for your help in advance : )

Hi Jaiesy,

In current version TR doesn't return 0 that correspond succesfull completion of the task. Now TR return RCI_Request from -6 to -1 that indicate successfull achivment one of 6 criteria.

Hi, Alexander Kalinkin,

I am using MKL version 10.2, and there is a chance for RCI_Request return 0.

In that case what should I do? Should I change to the newest version or ?

Thanks a lot ; )

HiJaiesy,

I was a bit wrong in previous answer - there is a chance for RCI_Request return 0 but it is mean that TR successfully completed one step (iteration of algorithm) but doesn't reached any stop criteria so you need to call _solve again. Thats why in TR example when RCI_Request is equal zero program calldtrnlsp_solve again in loop.
