How to use the Intel® Cluster Checker v3 SDK on a cluster using multiple Linux Distributions

Linux based HPC clusters can use different Linux distributions or different versions of a given Linux distribution for different types of nodes in the HPC cluster.

When the Linux distribution on which the connector extension has been built uses a glibc version 2.14 or newer and the Linux distribution where the connector extension is used, i.e. where clck-analyze is executed, uses a glibc version lower than 2.14, clck-analyze is not able to execute the shared library of the connector extension due to a missing symbol.

clck-analyze will show a message like this:

    OpenCL GPU access on Windows over RDP/Remote Desktop

    I would like to be able to detect and access the Intel GPUs using OpenCL even over RDP/Remote Desktop sessions so that I can deploy applications that can utilize the full system capabilities even without direct console access. Right now, it appears that I would have to switch to use an alternate remote access client like VNC to keep the Intel video drivers loaded and keep the GPU accessible.

    With STEM Education, Women Can Create Both Technology and Their Own Futures

    The decline of young women's participation in science, technology, engineering and math (STEM) education in the U.S. is alarming for many reasons, but it's especially resonant for someone like me, whose cultural heritage is Indian. (Watch this short video, where I discuss these topics in person.)

    Events not getting their ref count incremented

    When I pass an array of 2 wait events into clEnqueueReadBuffer, with one event created manually, the ref counts are not incremented.

    As I understand, all events passed into cl methods should get their ref counts incremented.

    This works correctly with my GPU, but not for CPU (WIndows 7 64 bit,  core i7 3770, latest Intel OpenCL driver for CPU)

    clSetEventCallback Oddity

    I suspect there's an aspect of clSetEventCallback that I'm misunderstanding. If you have a look at this simplified code below, you can see a kernel call, followed by a clSetEventCallback. The program then sits and waits on a windows event (inside the callback) to be set.
    If the clSetEventCallback is immediately followed by a clFlush(), then the callback is called and the wait released as expected. However without the clFlush, the kernel is never called, nor its callback, and the wait is eternal. What am I missing here?
