Debug UEFI code by single-stepping your Coffee Lake-S hardware CPU

~ hucktech ~ Leave a comment

Teddy Reed of Facebook has a new blog post on using Intel DCI, UEFI Tool, Intel System Studio, and other tools:

TL;DR, if you have a newer CPU & chipset you can purchase a $15 off-the-shelf cable and single-step your hardware threads. The cable is a USB 3.0 debugging cable; and is similar to an ethernet crossover cable in the sense that the internal wiring is crossed. Be careful with this cable as unsupported machines will have undefined behavior due to the electronics of USB.

Intel roadshow for Xeon Phi code modernization

~ hucktech ~ Leave a comment

Intel, in partnership with Bayncore, is doing a free roadshow, 1-day workshop in a few European cities, on “code modernization” for the Intel Xeon Phi processor. So far, Dublin, Cambridge. and Barcelona are the only 3 cities listed in the tour. The event is free, so if you’re in the area, use Intel System Studio, and do parallel processing and other coding techniques that need “modernization”, check out this event. Agenda:

INTEL TECHNOLOGY PLATFORM FOR HPC & PROCESSOR UPDATE
MEET INTEL PARALLEL STUDIO XE 2016 – WHAT’S NEW?
OPTIMIZE AND PERFORM WITH INTEL MPI
HPC MEETS BIG DATA – CODING HIGH-PERFORMANCE ANALYTICS IN C++ USING INTEL’S NEW DATA
ANALYTICS ACCELERATION LIBRARY
BEST PRACTICES FOR VECTORIZATION – PARALLELISM AT CORE LEVEL (SIMD)
TUTORIAL – REAL WORLD EXAMPLES FOR VECTORIZATION
CODE OPTIMIZATION IN A 3D DIFFUSION MODEL
CASE STUDY – PAIRWISE SEQUENCE ALIGNMENT WITH THE SMITH-WATERMAN ALGORITHM

Intel System Studio now targets FreeBSD

~ hucktech ~ Leave a comment

Intel System Studio (ISS) is a GUI IDE to build embedded systems. ISS normally is only available on Windows and Linux. Now it is also available on FreeBSD!

Intel® System Studio (ISS) 2016 for FreeBSD* Beta provides a comprehensive embedded tool suite solution for developing, optimizing, tuning and deploying 64-bit system and application C, C++ code running natively on FreeBSD* host systems. This product release includes the following components:

  • Intel® C++ Compiler 16.0 Beta for FreeBSD* systems
  • Intel® VTune™ Amplifier 2016 Beta for Systems for FreeBSD* Targets

ISS includes the Intel C Compiler, the only C Compiler that targets EBC, the EFI Byte Code. Normally ISS is a commercial-only product, but they sometimes have a shareware-style free edition available during beta periods. AFAIK, there is not a free version of Intel C Compiler.

Thanks to the FreeBSD News site for finding this information.
