Issue: "Start RT GPU CUDA" ist crashing Modo

[Uhlhorn]

Hi,

If I click on Start RT GPU CUDA Modo is crashing always.

I’m using:
iMac 27" i7 (late 2012)
32 GByte RAM
NVIDIA GeForce GTX 680MX 2048 MB
CUDA Driver Version: 7.5.22
GPU Driver Version: 10.8.14 310.42.15f01
Mac OS X: 10.11.3 Beta (15D13b).

Is it a bug? And is it possible go get some information about the crash (is there log file or anything)?

RT GPU CUDA isn't working on Mac OS X in our official 3.01.01 build.

The latest nightly builds have this fixed.
You can request access to those by sending an e-mail to support[at]chaosgroup[dot]com

The 3.01.01 build doesn't crash over here (on an iMac as well, but on Mac OS X 10.11.2 ), so I would suggest updating your GPU drivers as well.
GPU Driver Version: 10.8.14 310.42.15f01 seems quite old, the latest starts with 346 or something.

You can get information about what V-Ray is doing in MODO's Event Log, but of course it is not possible to see it after a crash.
I need to add an option to have the messages saved somewhere on disk.

Greetings,

I have installed the drivers some weeks ago, and some days ago I was updating the drivers. Actual the drivers say the there is no newer software.

Where can I get newer drivers from?

Hm, yes, the CUDA driver seems to be the latest version.
The GPU driver might not be the latest though, not sure if it matters for a CUDA application, but it might.
Can you try updating the GPU driver ? Trying to find the latest version from nvidia.com is a bit confusing, since it doesn't list Mac OS X as an operating system, when the GeForce 600M series is selected.

Google finds this : http://www.nvidia.com/download/drive...px/92173/en-us
but the bottom of that page says "BETA support is for iMac 14,2 / 14,3 (2013), iMac 13,1 / 13,2 (2012) and MacBook Pro 11,3 (2013), MacBook Pro 10,1 (2012), and MacBook Pro 9,1 (2012) users.", which doesn't sound right.

Hmm, this driver can not be installed:

Mac OS X version is not compatible
Mac OS X version 10.11.3 (15D13b) is not supported with this package. Please see NVIDIA’s website for further driver information.

Hmm, this driver can not be installed:

Ok, maybe it is best to ask support for nightly build access, and then try this build : https://nightlies.chaosgroup.com/mai...tlies/20160108

Thank You. I have sent a mail to the support

In 10.11.4 Beta (15E27e) there is a new version of the GPU Driver. It’s now: 10.10.1 310.42.15f01
