Extended addition (described below ) is one of the most performance critical kernel in our code (that implements important functions from sparse linear algebra).
I'm having some troubles while using the _mm512_extload_epi32 instrinsic. I want to load 16 signed char elements and convert them to int32 vector. The instruction is:
___m512i v = m512_extload_epi32(buffer, _MM_UPCONV_EPI32_SINT8 , _MM_BROADCAST32_NONE, _MM_HINT_NONE ); //buffer is aligned to 16-bytes
When I compiled it, icc said "catastrophic error: Invalid upconversion argument to intrinsic."
icc version 14.0.2 (gcc version 4.4.7 compatibility). MPSS version 3.1.4.
Can someone tell me where is the mistake?
I am trying to use gather function in the follow code on MIC. When I ran it, it said "Segmentation fault". Can someone tell me how to fix it?
#define N 32
double a[N], b[N], c[N];
for(int i = 0; i < N; i++)
a[i] = 1.0*i;
b[i] = 2.0*i;
c[i] = -1.0;
While using the shuffle operations in micvec.h (provided by Intel Composer 13.1), I found the template function of shuffle() cannot be correctly compiled. The contents are as below:

Here at the Intel Developer Zone, we’ve launched an exciting platform called the "Share Your App Project”, a great way for interested developers to share what they’re working on with the greater developer community. Every month, we plan to recognize a few apps for innovation, creativity, and intuitive and interesting use of technology.
We have issues with our program which uses offload mode on Windows. We think our issues are possibly related with something with coi_host.dll. We have callstacks that mention coi_host.dll but the callstacks do not seem to correspond to what we are observing with our code.
