I'm getting bad performance with MPI barriers in a microbenchmark on this system configuration:
Hello, I would like to run an asynchronous calculation, but am having a hard time understanding with the intel user and reference guide are saying regarding this. I have code that looks like the following.
I have a system with 4 MIC cards.
When I start a process in offload mode on mic0, one core of other mic cards is occupied with coi_daemon process. Why?
Unfortunately, I get high variances in timing when other mic cards are used by other users.
This post covers two questions. I actually just need a (positive) answer for one of them, as that would be enough to solve my problem. But it would be nice to get an answer for both.
1. Is it possible to write to disk from the offload region?
2. How can I use memory allocated inside the offload region in the host?
I've got a problem with my program. It's simple code which show my problem.
Is it possible to setup an external network bridge for the PHI on using a windows based operating system?
This information is not provided in the User's Guide.
I have simply highlighted the PHI and External network adapters and created a bridge.
What are the next steps for this to work?
Do i absolutely need to use Linux for this feature?
I would like to ask if there is a way to use sssd i stead of ldap for user authentication to mic?
Thank you very much

I joint the HPC Code Modernization Workshop held in Stockholm on June 3'rd 2015.
At the workshop we were offered an Intel software/hardware bundle including "Intel Parallel Studio XE Cluster Edition and 1 Intel Xeon Phi 5150P".
My development environment is a IBM Flex x240 computer node with 2 Intel(R) Xeon(R) CPU E5-2643 0 @ 3.30GHz CPU's and 256 GB RAM.
In order to install the Intel Xeon Phi 5110P, I need to by a Flex System PCIe Expansion Node, but I am a bit unsure if the offered Xeon Phi processor can be installed.
I would like to know, how where statement affects vectorization.
My belief is its bad for vectorization.
Here is a short part of the original code
where ( LMASK ) WORK1(:,:,kk) = KAPPA_THIC(:,:,kbt,k,bid) & * SLX(:,:,kk,kbt,k,bid) * dz(k) . . . endwhere
Even the Optrpt seems to suggest the same.
