Begin forwarded message: From: Intel Customer Support <supportreplies(a)intel.com<mailto:[email protected]>> Subject: [Argonne-intel] Intel Developer Products Support - Update to Service Request#:02522122 Date: March 1, 2017 at 5:11:08 PM CST To: "argonne-intel(a)alcf.anl.gov<mailto:[email protected]>" <argonne-intel(a)alcf.anl.gov<mailto:[email protected]>> [https://c.na37.content.force.com/servlet/servlet.ImageServer?id=0150P000006…] Hello, An update was made to service request on March 1, 2017: Hi Steve, Kumar, The compiler developers did find a code problem relating to shared variables inside a workshare, and this has been fixed in 2017 update 2 compiler, (17.0.2), which is now available for download from the Intel Registration Center. That said, a temporary array is still allocated for each thread, and the program will still seg fault unless you set a large value for OMP_STACKSIZE. The developers consider that this is not in itself a stability issue, but rather one of optimization (of memory usage), and think that this should be treated as a separate issue. Would you like to pursue this, and do you wish me to create a separate issue to track the temporary array creation and consequent large thread stack requirement?

[JLSE-Intel-NDA] missing stuff in /sys/devices on KNL DAP box
by Romero, Nichols A. 28 Feb '17

28 Feb '17

I apologize if this is a duplicate (though I think my earlier message got blocked from the list). --- Hi, This is related to the KNL DAP box which is similar to the JLSE KNL nodes. Our KNL DAP box, is missing some devices in /sys/devices, in particular it is missing: /sys/devices/uncore_* I did some investigation and they seem to be present with an old mpsp CentOS kernel: 3.10.0-327.el7.centos.mpsp_1.3.1.45.x86_64 Otherwise, these devices do not get generated at boot time with default CentOS 7.2 or 7.3 kernel. Does anyone know what might be going on? I unfortunately, cannot run the mpsp kernel by default due to other issues related to VTune. -- Nichols A.
