...when R closes. Not on garbage collection but only on exit. Is there anything in the R internals that explain why this is happening? The relevant C++ code is --- void gpualloctest(){ char * _a; cudaMalloc(&_a,sizeof(char)); cudaFree(_a); _a=NULL; } --- from gpu.cu gputest<-function(){ cat("testing allocation on gpu\n") Module('test','gputest')$gpualloctest() cat("Test successful\n") cat("Collecting Garbage\n") gc() cat("done.\n") } --- from gputest.R As you can see...

https://bugs.freedesktop.org/show_bug.cgi?id=111724 Bug ID: 111724 Summary: NVE6 (GK106) memory re-clocking breaks GpuTest plot3d benchmark Product: xorg Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: not set Component: Driver/nouveau Assignee: nouv...

I have looked at problem with Fermi GPUs where changing to higher clock led to really bad perfomance (with GpuTest 20x worse perfomance) and later also crashes of the nouveau. It seemed to be affected by Shader Clock in Voltage Entries in the video BIOS. Disabling BYPASS_PLL_CHECK in CLK0_CTRL seems to completely fix the issue. I have tried to search this BYPASS_PLL_CHECK in Nvidia traces but seemed it wasn'...

was "nv50/ir: PostRaConstantFolding improvements" before. nothing really changed from the last version, just minor things. Karol Herbst (5): nv50/ir: restructure and rename postraconstantfolding pass nv50/ir: implement mad post ra folding for nvc0+ gk110/ir: add LIMM form of mad gm107/ir: add LIMM form of mad nv50/ir: also do PostRaLoadPropagation for FMA
