Download this 5-minute video featuring executives from Red Hat and Intel talking about the companies' joint efforts to deliver real business value for cloud computing. Jim Totton is VP of the RHEL Business Unit at Red Hat, and Jason Waxman is the GM of Cloud Infrastructure at Intel's Data Center Group.
In 2013, the Intel® Software Academic Program, working together with the Intel Software Development Tools Team, brought Intel Software Conference to São Paulo and Rio de Janeiro. The conference received 238 attendees in total, delivering hands on lab trainings and theoretical lectures. The infrastructure of the Manycore Lab implemented in 2013 was used to deliver this experience on a live Intel Xeon-Phi system. 2014 should be even bigger and better, including a Parallel Software Marathon. The pictures below highlight the exciting work that took place over the 5 days of conference.
I am trying to run a mpi program on the MIC using 240 threads, and I use the Vtune to analyze my program and find the L2_DATA_READ_MISS_CACHE_FILL/ L2_DATA_READ_MISS_MEM_FILL is too high(about 88:1).
I am trying to install and use OpenCL on my local cluster, of which the node have a CPU and 3 MIC cards. I have installed it successfully and running clinfo will return the right information (as expected). However, when running a simple example, e.g., vector addition, only device0 can run and return normally. The other two devices (device1 and device2) can create context, kernels normally, but hangs after that.
When strack the program, it gives the following message. Do anybody have an idea of the reasons?
I use OpenCL in my program, and i need to protect opencl code from reading by other users. Compile code to binary maybe the option, but if exist some way to decompile it, this option is useless. I cant allow to somebody steal my opencl code. How i can do opencl protection? Thanks!
How does the cast operation _mm512_castps_pd work?
A __m512 data type holds 16 floats i.e. 16 elements. Contrary to that a __m512d data type can only hold 8 elements -- so what happens if I use the following instructions
__m512 a_ = _mm512_set1_ps( 2.0 ); __m512d b_ = _mm512_castps_pd( a_ );
Is it possible to load data from memory with _mm512_load_ps and then do a "cast operation" from float to double precision into two __m512d registers.
Yep. Here is another blog series from yours truly. Unfortunately, it will delay my long awaited – at least by me – discussion on measuring power.
Here is a rough outline for the blogs:
Ultrabook with QHD display == Wow!
My professional programming experience goes back to 1972. Every once in a while a technology comes out that has a high rating on the Wow! factor. When the technology is affordable, the combination makes it must-have productivity improvement product to incorporate into software development process.
