Run-time error: undefined symbol: _intel_fast_memmove

Hello everyone,

I am trying to do something rather exotic. I think I have reached a good point in the process, but now I got stuck.

More specifically, I have a MATLAB program, part of which is very computationally intensive. I have successfully put this part into a MEX file (written in C) and parallelized it using OpenMP. So, the MATLAB part only sets up a bunch of arrays and the time-consuming part is done in the MEX file. Everything fine up to this point.

Is there a usable intrinsics guide?

Is there a usable intrinsics guide?

Note, I have the Intel(R) Intrinsics Guide V3.01. However, it is not very productive in finding what you want (need) nor is it comprehensive.

For example, you cannot specify a filter by type. Example, I want to see only _m128i types.

Also, this guide is not comprehensible as it contains only the mmx/sse/avx/avx2/avx-512 intrinsics - it does not contain all the other "intrinsics" such as the meta language intrinsics (e.g. type traits  is_convertable).

Is there such a guide?

IPoIB in Xeon Phi



I am configurating Lustre in Xeon Phi. But only works with mic0 (mic0-br0-eth0) interface. It's possible to configure intel xeon phi scif0 interface with IPoIB and connect lustre inside Xeon Phi by Infiniband (o2ib).



Thanks in advance! 

Seg. fault when using _m512_mul_pd

I'm an undergrad student working on some code for that is supposed to just do some simple matrix multiplication. The professor I'm working for has purchased a MIC and I'm trying to get things working using some of the C++ intrinsics. In particular I'm using _m512_mul_pd to try to multiply two  together and I'm storing the result in another vector. However, when ever I have any code that accesses the variable I use to store the result of the multiplication in I get a seg. fault. Any ideas of why this is happening and what I can do to fix it?

miccheck -ssh fail unexpected


i am using mpss 3.2.1 and i have configured an internal bridge in this way:

micctrl --addbridge=br0 --type=internal --ip=
micctrl --network=static --bridge=br0 --ip=

Everything went fine and after restarting mpssd i am able to login on both mic cards.

But when i try to check using miccheck tool, i obtain this failure:
