Error when expanding benchmarks to two or more nodes

Hello, I'm running mp_linpack in two nodes(I have grasped how to run in one node :) ), I changed the path to mp_linpack/bin_intel/intel64, and modify the HPL.dat to set P=1, Q=2. Then I created hosts file, whose content is:

mic01:1
mic03:1

mic01 and mic03 is the two nodes where I want to run linpack. Then I use the command in MKL_userguide.pdf:

mpirun --prefix 1 -n 2 -hosts Node1,Node2 \
-genv MIC_LD_LIBRARY_PATH $MIC_LD_LIBRARY_PATH \
-genv LD_LIBRARY_PATH $LD_LIBRARY_PATH ./xhpl_offload_intel64

How to install Vtune Amplifier 2015 vtsspp on MPSS2.1.6720

I'm using mpss_gold_update_3-2.1.6720, with a uos version of 2.6.38.8-g5f2543d.

I'm now trying to install the vtune amplifier 2015 on this mpss, so I need sep3_15-k1om-2.6.38.8-g5f2543dsmp.ko and vtsspp-k1om-2.6.38.8-g5f2543dsmp.ko. But I can find only sep3_15-k1om-2.6.38.8-g5f2543dsmp.ko and vtsspp-k1om-2.6.38.8-gd50f2a5smp.ko, but not vtsspp-k1om-2.6.38.8-g5f2543dsmp.ko.

Q on memory comparison optimization

Hi All,

I am using AVX/SSE instructions to replace memcmp and our workload includes comparing 64 bytes and occasionally 64 and 128 bytes. I am using following function cmp32 for 32byte comparisons and extend it 2 times for 64 or 4 times for 128 bytes and I am hardly getting 1% performance improvement. Testing was done on Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz, Ubuntu 14.04 x86_64.

I tried replacing following lines
vcmp = _mm256_cmpeq_epi64(xmm0, xmm1);
vmask = _mm256_movemask_epi8(vcmp);

changes in CEAN implications re vectorization in next release?

I note that premier.intel.com is open for submissions for the first time in months, so I submitted a ticket.  It still looks like setting up premier for beta 16 has not been completed, as the form requires choosing compiler version 15.0 or earlier from the pull-down.

I'm curious whether Cilk(tm) Plus is under deprecation, in view of the comments at IDF last year that Intel would not sponsor publications on it, and the lack of follow-through to make gcc -fcilkplus viable.

As to changes in behavior in the beta test:

mic stuck at booting state

[root@amax ~]# micctrl -s
mic0: booting (mode: linux image: /lib/firmware/mic/uos.img)
mic1: booting (mode: linux image: /lib/firmware/mic/uos.img)

I have two mic cards, but they just get stuck at booting state, and never be online. No matter I reboot the host or restart the mpss service, it just stayed at this state. Any help please? Thank you very much!

Communication with sampling driver failed

I am trying to do General Exploration analysis, and the following error appears almost immediately after trying to attach to the process,

"Communication with sampling driver failed".

I'm running on Windows 7, on a Intel Xeon CPU E5-2680 (2 processors). Doing the Basic Hotspot Analysis went fine. Any ideas - or things I could try?

 

Cheers,

-J
