JodyLS27 Posted July 14, 2019 Share Posted July 14, 2019 Hi there everyone. I have this very Unique issue that is both on Windows 10 and Linux (Mint 19.1, Ubuntu 18.04, fedora 29 and 30) where I will run a Simulation (Pyro, Particles or Fluids) and it will say Complete but only do 159/600 frames. The number of frames it dose is random and could change from sim to sim. System specs: CPU - Threadripper 2970WX (29 Cores - 48 Threads) RAM - 128GP of 2666 Corsair Vengeance LP SSD - 2TB, 1.7TB Free SPU - 1200W Cooler master Motherbaord : MSI Gaming Pro Carbon AC Houdini 17.5 Latest Build. Its not a Ram or CPU issue, I Rand them together at full Load in Prim 95 for 10 to 15 min and it was fine, no Hick ups or Heat issues. Things I have tried include changing the GPU from AMD to Nvidia (Yes removed the drivers to install Nvidias) Changed to an HDD, removed Performance boost in the BIOS, I reinstalled the latest Bios as well. I feel like its a Timing issue. Something is Causing the Sim to Complete, its like the write to disk is taking to long or something because if I lower the Res of the Flip sim, it will complete the cache but the result is to cores for a final portfolio piece. Please, Any Advice would be Greatly Helpful. Quote Link to comment Share on other sites More sharing options...
JodyLS27 Posted July 14, 2019 Author Share Posted July 14, 2019 LOL Here is a quick update. I tried to go into the DOP network and got this issue Segmentation Fault and Houdini Crashed. Bellow is the Log it Produced. crash.River_Simulation_536.jodys_7836_log.txt Quote Link to comment Share on other sites More sharing options...
Skybar Posted July 14, 2019 Share Posted July 14, 2019 Are you running out of RAM? It can happen if your sim is too high res. Quote Link to comment Share on other sites More sharing options...
JodyLS27 Posted July 14, 2019 Author Share Posted July 14, 2019 Hi there @Skybar and thank you for your Reply. Nope, My Fluid Sim gets to around 60% of Ram usage so I dont think its a ram issue. Here is the strange thing, When I first got the system, I worked Perfectly and I could run this sim with up to 40 Million particles and it would take around 36 to 40 hours to cache 700 frames and get up to around 115 GB of ram, so something strange has happened and I cannot think of a Solution Quote Link to comment Share on other sites More sharing options...
Skybar Posted July 14, 2019 Share Posted July 14, 2019 Hmm yeah sounds strange. Try it in a fresh scene and see if that helps, otherwise probably contact support if you havent already. Quote Link to comment Share on other sites More sharing options...
JodyLS27 Posted July 14, 2019 Author Share Posted July 14, 2019 Yea I have tried it and I get the same issue. I have contacted support and they have been helping me along the way, but the Segmentation Fault I have had before but It never got solved and The system has been down for a while. I am busy downloading the New windows 1903 and then I'll do some updates. I'll then Uninstall Houdini and any drivers and restart and Then reinstall and see if that Fixes it. I am trying anything here. Quote Link to comment Share on other sites More sharing options...
JodyLS27 Posted August 13, 2019 Author Share Posted August 13, 2019 I have found the Issue and it was a Faulty Ram Stick. If you have a similar issue and own windows 10, You can run a memory test and it will tell you if you have a faulty ram stick. Quote Link to comment Share on other sites More sharing options...
