  • Memoria de gran ancho de banda (HBM): ¿cómo beneficiará a las aplicaciones?

    Objetivo

    El primer paso hacia la conveniencia de usar la MCDRAM o la memoria de gran ancho de banda (High Bandwidth Memory, HBM) es evaluar el uso de ancho de banda de memoria de la aplicación.

    En este artículo se brindan instrucciones básicas sobre perfilar y evaluar la utilización de ancho de banda de memoria de una aplicación mediante el uso de Intel® Vtune™ Amplifier en procesadores Intel® Xeon® (IvyBridge/Haswell) y coprocesadores Intel® Xeon Phi™ (Knights Corner).

    31S1P: BSOD or Device Connection Lost

    Hi.

    There are some kind of instabilities with my Xeon Phi 31s1p. With or WITHOUT(!) a job on the coprocessor there are events like

    june 16 2015 21:02:31: Warning: mic0: Device connection lost!
    june 16 2015 21:03:47: Information: mic0: Device connection restored

     

    With an OpenCL job the situation gets worse: it may loose connection or raise blue screen of death :) IRQL_LESS_OR_EQUAL in some MPSS dll (I will take a screenshot later).

    Data alignment problem

    Hi there

    I was trying to offload some computation to MIC using "pragma", sending data addressed by a pointer p, then how to ensure the alignment of data on MIC after MIC recieved it? Does" __assume(p, 64)" work?I was trying to use instrinsics to load data to the vector RF, which requires the alignment of data.

    Another problem, that I was trying to active lots of threads for the calculation using "#pragma omp parallel for", and some arrays inside the loop must be thread private while also 64-byte aligned.

    Coarray - Internal compiler error / Wrong results

    Compiling this program with ifort version 15.0.1 gives me:

    testarray.f90: catastrophic error: **Internal compiler error: segmentation violation signal raised** Please report this error along with the circumstances in which it occurred in a Software Problem Report.  Note: File and line given may not be explicit cause of this error.
    compilation aborted for testarray.f90 (code 1)

    Here is the code:
