Hello, There's a long-standing bug on nouveau (this is a sample bug, but the issue has been around for a while: https://bugs.freedesktop.org/show_bug.cgi?id=85465) whereby we attempt to use the second PCOPY engine on GF116, and it is sometimes does nothing, despite mmio register 22500 saying that it's not disabled (0x22500 == 0 for this user). In the bug you can see a dump from

Dear Mehdi, I've changed your example a little bit: float saxpy(float a, float *x, float *y, int n) { int j = 0; for (int i = 0; i < n; ++i) { y[j] = a*x[i] + y[I]; // Change 'I' into 'j'? ++j; } } I get this code below, once I replace 'I' with 'j'. We are copying n positions of both arrays, 'x' and 'y': float saxpy(float a,

Dear LLVMers, we have released a tool that uses LLVM to insert OpenACC or OpenMP 4.0 directives in programs. You can use the tool online here: http://cuda.dcc.ufmg.br/dawn/. Our tool, dawn-cc, analyzes the LLVM IR to infer the sizes of memory chunks, and to find dependences within loops. After that, we use debug information to translate the low-level information back into annotations that we

Hi Ilia, Actually 0x90b8 is different than copy engine. I'm not very familiar with it, but 0x90b8 is an engine for performing LZO decompression as part of performing the copy. It has a variety of limitations (e.g., cannot handle blocklinear format), and was only in a few Fermi chips, as I understand it. It is probably easiest to just ignore it. You can distinguish this decompress engine
