nuaga chomp Posted July 22, 2009 Share Posted July 22, 2009 I think I may know the answer to this question but here goes.... I am running the apprentice version of Houdini on a 48 gig, 8 core Linux machine and its incredible slow. For some reason Houdini will only use 1 gig of that 48 gigs (its acting like its operating on a 32 bit machine). The catch here is that the gpu is part of the mother board i.e. this is a blade from a server. Is my lack of dedicated graphics card the cause for Houdini's poor performance? And is there a permission issue causing to have limited access to the 48 gigs? Are these two problems causing the poor performance or is it mainly a gpu issue? Any help you could give me would be greatly appreciated. thanks Quote Link to comment Share on other sites More sharing options...
edward Posted July 23, 2009 Share Posted July 23, 2009 Well, dumb question: Did you install the 64-bit version of Houdini? Besides, how do you know it will only use 1 GB of memory? Have you got other apps to use more? Also, how are you telling this memory size? Note that resident memory size and VM size are two different things. Are you running the memory hscript command in Houdini? Quote Link to comment Share on other sites More sharing options...

nuaga chomp Posted July 23, 2009 Author Share Posted July 23, 2009 Its the 64 bit version of Houdini Apprentice for Red Hat. But we are running Cent OS. Red Hat is the closet thing to Cent OS I am told. But it is acting like a 32 bit program for some reason. Quote Link to comment Share on other sites More sharing options...
nuaga chomp Posted July 23, 2009 Author Share Posted July 23, 2009 Also: this is the first app running on this machine. (we will be running some Finite Element Analysis software on it soon as well). So no other applications are running on this machine at this point. We have a Linux/computer scientist handling the benchmarking on the machine so I'm not sure what software he is using to find the memory size. But this is 48 gigs of residence memory. But for some reason Houdini stops at 1 gig and kicks into virtual memory. The whole point of having 48 gigs is to never go into virtual memory. The hard drives (we have a terrabyte) are just too slow... Quote Link to comment Share on other sites More sharing options...
eloop Posted July 31, 2009 Share Posted July 31, 2009 The virtual memory use after 1 gig would suggest that it's not Houdini specific, rather it's an operating system level problem. -Drew Also: this is the first app running on this machine.
