Thank you alot for your Help Marty It was simple , i Downloaded and installed the Nvidia Driver from Nvidia website , then installed it after that i got to a problem where my screen goes blank on Startup , I did some searching and now using the "nomodeset" in grub . and then its all working OpenCL Platform NVIDIA CUDA Platform Vendor NVIDIA Corporation Platform Version OpenCL 1.1 CUDA 7.0.41 OpenCL Device GeForce GTX 970 OpenCL Type GPU Device Version OpenCL 1.1 CUDA Frequency 1329 MHz Compute Units 13 Device Address Bits 32 Global Memory 4095 MB Max Allocation 1023 MB Global Cache 208 KB Max Constant Args 9 Max Constant Size 64 KB Local Mem Size 47 KB 2D Image Support 32768x32768 3D Image Support 4096x4096x4096 But I also read that the "nomodeset" can prevent Graphics Acceleration . is that true ?

Houdini Version 14.0.335 OpenGL Vendor: NVIDIA Corporation OpenGL Renderer: GeForce GTX 970/PCIe/SSE2 OpenGL Version: 4.5.0 NVIDIA 346.72 OpenGL Shading Language: 4.50 NVIDIA Detected: NVidia Consumer 4096 MB 346.72.0.0 as for the OpenCL : No Configured OpenCL Device , i guess thats where the problem is ?

Hello , Not sure how to post the Error , But here is a screenshot

Hello Marty , Thank you for fast reply , Actualy the simulation is so simple , just a ground plane and a torus and then i convert torus to Grain for example , once i click on use Open CL , the node turns to red and i get an error, The same simulation worked on my laptop on windows with the intel HD 4600 so i dont think it's VRAM problem . I will post the error later when i get to my machine . Regards

Hello , Everytime i try to use openCL on houdini i Get an Error , Not sure why . Here are my PC specs : OS : Ubuntu 15.04 CPU: I7 4790K GPU : GTX 970 RAM : 16 GB Kindly Help ! Regards

thank you for sharing , i started learning houdini too , i believe your notes are great help

Hello I want to thank you alot for your advice . i did get the intel I7 4790K and the GTX 970 . and they are working very fine . Thank you alot

Thank you alot , you been great help i will do alot of simulations using the open cl , but yet i decided to go with Nvidia . But now i feel greedy for going for th GTX 970 instead of the GTX 960 , but i should pay more money for that . Now the questions is : is the GTX 970 would give a better performance the the 960 ? which makes me want to go for it ? Regards

Hello , first of all thank you alot for fast reply , so i see that the Intel prcoessor worth the cost difference after some research , besides that with AMD i will have to get very good water cooling system for processor but i have quesition about the VGA , i read that OpenCl is way much better on the AMDs than Nvidias , is that ture in that case ? Also is the GTX 960 is not listed in the supported Graphics cards in sideFX website , So that means its gonna perform Bad ? Regards

Hello Everyone , I am trying to build a computer for using Houdini , and iam really confused between choosing some parts , that would perform good with houdini With no Problems . So kindly help me too choose between the following First : CPU 1- AMD FX-9590 Vishera 4.7GHz Socket AM3+ 220W Eight-Core Desktop Processor - Black Edition 2 - Intel Core I7-4790K Devil's Canyon Quad-Core 4.0GHz LGA 1150 Desktop Processor Second : VGA card 1-SAPPHIRE TRI-X R9 290X 4GB GDDR5 2- MSI GTX 960 GAMING 4G GDDR5 3 -Gigabyte GeForce GTX 760 OC 4GB GDDR5 Windforce 3X 4 - SAPPHIRE VAPOR-X R9 280X 3GB GDDR5 OC 5 - SAPPHIRE VAPOR-X R9 280X 3GB GDDR5 TRI-X STD WITH BOOST (UEFI)
