Xeon Phi 5110P on Dell Precision T3600 Workstation installation

Hi,

has anybody successfully installed a Xeon Phi 5110P on a Dell Precision T3600 Workstation?

My card is in a PCIe v3 x16 slot but it doesn’t show up in BIOS or “lspci”. Blue LEDs on the card are blinking irregularly, 6pin and 8pin PCIe power connectors are plugged in (my first error ;-). I flashed the BIOS to revision A14, so that I was able to set the “PCI MMIO Space Size” BIOS Parameter to "Large". I also removed my Nvidia Tesla C2075 from the board, because together they took more power than the system can provide (my second error ;-)

Using micnativeloadex, how to use args ?

Hi,

I am a very beginner with the Intel Phi, and I am trying to do something that is maybe not possible.

I have this binary file called upcDemo

And I run it this way: upcrun -n 12 upcDemo 

(This will run the program on 12 threads)

I have tried many syntax with micnativeloadex...but I got errors, here is what I tried:

OpenCL drivers releases and bug report contact

Hello,

My company is in the process of validating our software against Intel OpenCL drivers (Xeon only, not Xeon phi)

We are currently relying on the 5.0.0.57 version for Linux and 5.1.0.25 for Windows.

Windows driver works like a charm, but we are struggling with instabilities using Linux 5.0.0.57 (Like kernels that work on a lot of other platforms (Including Intel's windows 5.1.0.25) crashing in a non deterministic fashion... Sometimes they work fine, sometimes not so good...)

Using Intel® VTune™ Amplifier XE to Tune Software on the 5th generation Intel® Core™ processor family

Download this guide (see Article Attachments, below) to learn how to identify performance issues on software running on the 5th generation Intel® Core™ processor family (based on Intel® Microarchitecture Codename Broadwell). The guide explains the General Exploration Analysis viewpoint available in Intel® VTune™ Amplifier XE. It also walks through some of the most common performance issues that the VTune Amplifier XE interface highlights, what each issue means, and some suggested ways to fix them.

    To start this post off, I would like to say that I do not take the term "bug" lightly - it gets thrown around on the internet often, but usually when someone does not understand the tool set. I hope this post is not one of those, but my research tells me otherwise. TL;DR clause: there appears to be a problem with get_global_size(dim) from the debugger.

    Lets start by defining a simple kernel (emphasis on simple) - set the value of the array element in an in/out buffer to its associated linear index:
