[SYCL] error: variable-sized object may not be initialized #887
Comments

Hi, Compiler gives the same error message on such code. I believe you need to initialize new_image using malloc_shared to use it in the kernel(preudo-code): However the crash after diagnostics is a bug. |

@romanovvlad thanks. I've changed the code following your tip but i have a similar issue. cagnulein/sycl-benchmarks@42d12d9 $ clang++ -O2 -g -std=c++11 -fsycl rotate_usm.cpp -lOpenCL -o rotate_usm.gpu
error: array initializer must be an initializer list

Hi, |

@romanovvlad i've tested in small arrays and it works, but with huge arrays (20000*40000 bytes) it gives me a segmentation fault. Looking with gdb this is the backtrace: Thread 1 "rotate_usm.gpu" received signal SIGSEGV, Segmentation fault.

Hm sounds like an issue in compute runtime, suggest creating issue there https://github.com/intel/compute-runtime/issues |
|
I have the feeling that you should use just a 2-D array instead of an array of array, since all the dimensions seem to be |
|
Hi @keryell , i've already tried the implementation with the cl::sycl::buffer (you can find here https://github.com/cagnulein/sycl-benchmarks/blob/master/rotate/rotate.cpp) and it works; it has only big issue: is really slow copying 800MB of data from the CPU to GPU and back. With the USM, if i didn't misundarstood them, i will run my alghoritm without copying around my buffer. And when it works, it works very quickly! I talk about 8x times faster than cl::sycl:buffer mode. What do you think? |
|
I see. It depends probably on the the GPU architecture. If you have some efficient shared hardware access between CPU and GPU that makes sense. Otherwise, a 2-D buffer with the right access mode in the accessors (such as write_only...) might be more efficient, with a minimal number of huge copy instead a gazillions of inefficient individual accesses, But my 2-D array suggestion was at the first place that it seems super inefficient to have arrays of arrays like instead of just a plain old C 2-D array: See https://godbolt.org/z/XkAWqe to get a simpler idea about why it should work (I have not tried myself with oneAPI...) I hope in the future USM will be extended to allow "just": that would provide also some nice alignment properties as a side effect. @jbrodman please :-) |

@keryell thanks. I've tried your implementation here https://github.com/cagnulein/sycl-benchmarks/blob/7bcbe77a5551551e5355ce87adfe91aff99ac96b/rotate/rotate_usm.cpp but i have compilation issue: $ clang++ -O2 -g -std=c++11 -fsycl rotate_usm.cpp -lOpenCL -o rotate_usm.gpu

IT seems the original problem has been resolved. Closing. Please, feel free to reopen if there are any concerns. |
I'm facing a strange compiler issue. The source code are here https://github.com/cagnulein/sycl-benchmarks/blob/fix_2d_array_with_array/rotate/rotate_usm.cpp
Is it supposed to be ok? If yes, how can i use a dynamic multidimensional array with USM?
