SDE Message: "No MPX support"

Hi,

I'm trying to run an application compiled with gcc 5.2.0 using MPX instructions in SDE 7.31.0 on Linux. (-fno-omit-frame-pointer -fcheck-pointer-bounds -mmpx)

SDE is used as: sde -mpx-mode -- MyApplication

The executable seems to contain a bunch of MPX related symbols, such as

__mpxrt_utils_free
__mpx_wrapper_memmove
__mpx_wrapper_mmap
__mpxrt_write

However, SDE outputs "No MPX support". What is this error-message hinting at? No MPX in the executable, no MPX support by SDE, no MPX support by the kernel....???

Простая методика оптимизации с использованием Intel System Studio (VTune, компилятор C++, Cilk Plus)

Введение:

  • Performance Gains for Ayasdi Analytics* on the Intel® Xeon® Processor E7-8890 V3

    Ayasdi deploys vertical applications that utilize Topological Data Analysis to extract value from large and complex data. The Ayasdi platform incorporates statistical, geometric, and machine-learning methods through a topological framework to more precisely segment populations, detect anomalies, and extract features. This paper describes how Ayasdi’s Analytics* running on systems equipped with the Intel® Xeon® processor E7-8890 v3 gained a performance improvement over running on systems with the previous generation of Intel® Xeon® processor E7-4890 v2.

  • Storage: Accelerate Hash Function Performance Using the Intel® Intelligent Storage Acceleration Library

    With the growing number of devices connected to the cloud and the Internet, data is being generated from many different sources including smartphones, tablets, and Internet of Things devices. The demand for storage is growing every year. For cloud storage developers who are looking for ways to speed up their storage performance, the optimized hash functions in the Intel® Intelligent Storage Acceleration Library (Intel® ISA-L) accelerate the computation, providing up to a 8x performance gain over OpenSSL* algorithms.

  • Performance Gains for SunGard’s Adaptiv Analytics* on the Intel® Xeon® Processor E7-8890 V3

    SunGard’s Adaptiv Analytics* allows traders to run pre-deal cost-of-credit calculations. Due to the volume and complexity of products, these calculations are often time consuming, causing delays that can lead to missed opportunities or taking action with incomplete information. This paper describes how Adaptiv Analytics running on systems equipped with Intel® Xeon® processor E7-8890 v3 gained a performance improvement over running on systems with the previous generation of Intel® Xeon® processor E7-4890 v2.

  • AVX512 for mobile?

    OK, so Skylake has been out for a month, and IDF is long past - but I still don't have an answer to one basic question: will there be any mobile chips that support a AVX512? At first my hopes had been dashed with the announcement that AVX would only be in available on Skylake Xeon, but then they were raised again when we found out that there would be a mobile Xeons for Skylake. 

    IA-32e 64-bit and compatibility mode

    Hi,

    From Intel developer manual I see

    IA-32e mode allows software to operate in one of two sub-modes:

    •          64-bit mode supports 64-bit OS and 64-bit applications
    •          Compatibility mode allows most legacy software to run; it co-exists with 64-bit applications under a 64-bit OS

    I have a quad-core with HT enabled i.e. 8 logical cores

    With KVM I want to run 32 bit and 64 bit VMs on a 64 bit Host OS. I want to allocate resources as follows

    Intel® X86 Encoder Decoder (Intel® XED) - new release site

     

    Until mid-2015, Intel XED had been distributed externally via Pin kits. However, with a recent change to Pin's C-runtime, it is now required that users of Intel XED obtain Intel XED compiled against a conventional C-runtime from a new site. The Intel XED library that comes with Pin is compiled only to work with the Pin C-runtime and not the standard runtime libraries available on every system. 

    The new site for distributing Intel XED is: 

    What is behavior of LD + OP instruction with register source and EVEX.b = 1?

    I'm confused about whether EVEX.b = 1 is allowed (and ignored) for instructions such as

    VPMINUD reg, reg, reg

    I cite this case because the gnu assembler testsuite has a case with this instruction but b = 1.  objdump disassembles the instruction without respect to the value of b.

    If the third operand is memory, then it can have {b32/64} attached and the value of b is significant.  But with a register, there is no exception or rounding inherent in the operation, so the value of b shouldn't matter.
