Blender Open Data

I’ve used several benchmark software to compare computer hardware especially nvidia GPU cards used for cuda programming.  One good free benchmark software is Maxon CineBench    , another is Unigine Haven

 

Here are surprising results generated from the new Blender Benchmark under its Blender Open data website program.

Quick summary/my findings:

  • less render time running Linux [LinumMint] than under Windows 10 [all things turned off], same hardware
  • SSD’s help

Linux run: Workstation with GTX1080 8Gb, GTX970 4Gb, 32Gb RAM, Quad core Intel processor. No SSD

Same hardware as above but run under Windows 10

Ran on same hardware, only using the GTX1080 8Gb , under Linuxmint – impressive resuly showing in my view and from cuda/nvidia research l did that the 4Gb of the 2nd graphics card limits the performance.

Computer Hardware

Linuxmint 18.1 – Cuda 9.1 Toolkit

Updating to the latest cuda development toolkit on Linuxmint 18.1 [with a GTX 1080+970]

Notes:

Reference links:

First, update to R390 Driver

Terminal commands

sudo dpkg -i cuda-repo-ubuntu1704-9-1-local_9.1.85-1_amd64.deb

sudo apt-key add /var/cuda-repo-9-1-local/7fa2af80.pub

Android Development Notes

Android Development Screen shots Notes, showing my settings, and most especially space costs on my dual OS laptop.

I dual boot into Windows 10 or  Ubuntu 16 on my laptop, l find the later faster and more Android sdk development simpler since l have to disable Hyper-V which l need on Windows 10 if l setup my full Android development on it – including emulator for testing.

Note, the complete tools below l chose and use take a lot of space. In my case, 30Gb, so plan accordingly.

Choice of SDK platforms.

My current phone is the LGG5 – running Android 7.0, however l also own an older Nexus 6 [no sim card/wireless plan] which l use for Android development testing running Android 7.1.1 [google nexus phones get the latest android releases frirst, unfortunately at least the nexus 6P not 6 is required for Android Oreo/8] 🙁 , and one of my target platform is Ikechukwu’s older samsung galaxy tablet which runs Android lollipop 5.0.1

I also chose Android MM – Marshmellow 6.0.1 since l have a tester using that version residing in Jos/Lagos on his phone – onijec [click here for his twitter link].

I want to test developing a small birthday countdown app for Ikechukwu, see if this works on multiple Android versions, test and use my google developer account/playstore and non playstore app distribution – before diving into more deep stuff like geo location based apps l am more interested in.

 

 

High Performance Computing

Top500 2017

“The Top500 list the 500 fastest computer system being used today. In 1993 the collection was started and has been updated every 6 months since then. The report lists the sites that have the 500 most powerful computer systems installed. The best Linpack benchmark performance achieved is used as a performance measure in ranking the computers. The TOP500 list has been updated twice a year since June 1993.”

“Mflop/s is a rate of execution, millions of floating point operations per second. Whenever this term is used it will refer to 64 bit floating point operations and the operations will be either addition or multiplication.

Gflop/s refers to billions of floating point operations per second and Tflop/s refers to trillions of floating point operations per second.”

Microsoft Certified Technology Specialist: Sql Server 2008…

mctsrgb

Passed my Microsoft Cerfification Exam on first attempt on Tuesday June 2nd! Score: 814

The certificate says l’m now recognized as a MCTS – Microsoft Certified Technology Specialist: SQL Server 2008, Implementation and Maintenance. The exam is the MCTS 70-432. Next goal is the 70-450 which has no study book in print, and the only material l can find so far is the CBT-NUGGETS training video on Exam 70-450 which is very good.

Materials l used to study other than multiple SQL Server instances on my laptop, Virtual PC Windows 2008 Machines with SQL Server 2008 installed – for database replication, mirroring and failover clustering practise!!!
– MCTS Self-Paced Training Kit (Exam 70-432): Microsoft® SQL Server® 2008 – Implementation and Maintenance by Mike Hotek (Very good, in-depth all round material, lab oriented book with real life stories). This seems to be the only main book out there.
– Self Test Software for MCTS 70-432, bought the download version of this excellent practise test program.
– Microsoft Sql Server 2008 Books on line (download the latest update from Microsoft)
– Took the official Microsoft 6231 course at SQLSoft (Beaverton)
– Books on Microsoft SQL Server 2005 exam 70-431
