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.

Home PC #2  Results below, newer PC, no SSD, 2 x GTX560Ti

Below results from Alienware 17 [4 years old] with Samsung Evo 500Gb SSD, GTX860M

Exploring Synology NAS 918+

My last NAS drive was the NetGear Stora [eons ago], and with all the changes in technology, drive space, 4k transcoding, plex, VM support l was due for an upgrade.

Enter the Synology NAS DS918+ which l settled for after lots of research over the QNap equivalent.

Below are some pictures and notes.Started off with just one 6Tb Seagate Barracuda Pro 128Mb cache 7200rpm drive that was on sale on amazon prime day.

Note, the transfer speed from external USB [WD 4TB external] into the NAS is about 55-68Mbs, if the External isnt accessible on the file station, you might need to reboot the NAS

For somereason l could not get it to see the contents of my Sandisk ExtremeSSD for quick copy into the NAS via the USB ports it came with, but it did see the contents of my WD External 4Tb usb drive.

This home/business NAS does offer a lot of applications – including:

  • Plex [ one core app l need]
  • VM hosting – OS independent, you can run Windows VM, Linux VM etc
  • drupal, github, wordpress, apache etc
  • Streaming media – photos, videos, documents work great – on all my PC’s, Samsung TV, PS3, XBoxOne, wireless devices on my internal home network etc.

Its really impressive how a modern day NAS is now a dedicated Linux machine with webhosting, network security, antivirus apps etc.

 

Exploring Adobe CC

Tried out the latest versions of Adobe Creative cloud – CC, and l must say l am impressed over the new features and capabilities compared to the former Photoshop CS6, Lightroom etc.

Had about 16Gb 7800 files of HD/UHD pictures and videos from a recent vacation, using 3 cameras – 7DM2, Sony A7 and for UHD 4K videos the Panasonic Lumix G85 – Unfortunately l could not get Adobe CS6 Photoshop using Camera Raw 9.x.x to accept the Lumix RW2 [I only shoot pictures in RAW] images, and using the versatile Adobe DNG converter – which works – was a workflow step l didnt want to go through.
Solution, l downloaded a trial version of Adobe CC Photoshop, which came witht he laterst Camera Raw 10.x.x and both Photoshop/Lightroom opened and processed all Lumix files seamlessly.

FlipFluids

Trying out Blender      Flip Fluids      – currently baking below lighthouse.blend sample file, 2-3 days so far, about 10 hours go go and 89Gb cache space used up!

Final space cost and rendered frame one, as of 5/29 6am [frame 0 rendered in 2.5 mins]

 

 

After 60 frames l got….

=====================

So far l have only been able to render up to 149 frames, then l get a cuda out of memory crash. I use both a GTX970 with 4Gb and a GTX1080 with 8Gb, l’ve tried with both and with each cards. Will keep you updated, meanwhile heres a render of the 149 frames
