We have a workflow application server with BerkeleyDB running on Windows 2012 - it is used for some critical back office operations at a leading Bank with upto 1000 concurrent users . The application runs on a machine with 

What is syntax for broadcast decorator?

The ISE doc only describes the decorator syntax with the single example {1to16} (document 319433-022 page 7).

I would assume that generally you write {1ton} where n = the full vector size / the single element size.  But it would be nice to specify this exactly.

However, GNU `as` will not accept {1to4] or smaller.  Furthermore, it does not accept a broadcast decorator with a 128- or 256-bit vector size.  If I use .byte to assemble 128- and 256-bit instructions, the disassembler shows the {1to8} or {1to16} decorator regardless of VL.  Example:

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 ;-)

PARDISO generates different results

Dear all,

I use PARDISO to solve a symmetric sparse matrix with size n=400,000 and number of nonzero=1,100,000. When I set the number of thread to one, I can get the same answer every time. But when I set the number of threads higher than 1 and run it many times, the answers become different every time (and never same as the answer by one thread). Are these weird results related to the issues of condition number or something else?

By the way, I have tried both  MKL 11.0.2 and 11.2.3.

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:

Cross-thread Stack Access

Hi All,

I'm running an OpenMP application (minimal example) :
  !$OMP PARALLEL DO

     DO KR=1,100

            Array_Out(KR) = Array_Input(KR)

    ENDDO 

  !$OMP END PARALLEL DO

 
I verified that I do not have data race (I get the same results with only one thread), however when running the application in the Inspector XE 2013 - I get a massage that I have cross-thread stack accesses. 

How can I prevent this behavior, and what is the practical effect if not on the results ?

Thanks in advance for your replies,
