Re: SVM(shared virtual memory) available on OpenCL FPGA?
My bad, HARPv2 is "Xeon CPU+arria10 FPGA" on a single chip. it seems SVM functionality is not yet there on Intel FPGAs on devcloud, as Intel is still stuck at OpenCL 1.0 or 1.2 and not fully confronted to OpenCL 2 or 3, Makes sense as intel shifted to OneAPI leaving OpenCL.2KViews0likes0CommentsRe: SVM(shared virtual memory) available on OpenCL FPGA?
@BoonBengT_Altera I am not asking particularly about that project, What i am asking is whether SVM is supported on intel FPGA. For example, Consider this one (vector addition) which is from INTEL, just download the source code and try to execute it. Add this below at the beginning of the main.cpp file to use SVM and compile using make #define USE_SVM_API 1 cd exm_opencl_vector_add_x64_linux/vector_add/ make Similarly compile for device (using pac_a10 device on devcloud). cd exm_opencl_vector_add_x64_linux/vector_add/device tools_setup -t A10DS aoc -report -v ./vector_add.cl Now since its compiled (vector_add.aocx generated), sign it if necessary. Run bin/host, and output says SVM is not supported. Initializing OpenCL Platform: Intel(R) FPGA SDK for OpenCL(TM) Using 1 device(s) pac_a10 : Intel PAC Platform (pac_ee00000) Using AOCX: vector_add.aocx The host was compiled with USE_SVM_API, however the device currently being targeted does not support SVM. Segmentation fault (core dumped) I just want to get confirmation if SVM support is there for intel FPGA's, because even in some official Intel OpenCL FPGA examples i have seen SVM usage, But here when queried for svm capabilties or even using clinfo, we get to know device not supported.2KViews0likes0CommentsSVM(shared virtual memory) available on OpenCL FPGA?
SVM OBFS, This project requires SVM functionality, They are using HARPv2 as per ReadMe, which is xeon+Arria10 FPGA. Even in Devcloud, we have Xeon+ A10 configuration. I know Intel supports OpenCL 1.2 and doesn't yet support OpenCL 2.0 Fully, just some functionality like pipes/channels are supported. I tried using SVM int* n = (int*)clSVMAlloc(context(), 0, sizeof(int), 1024); if(!n) cout<<"allocation error\n"; But getting allocation error. Is SVM available on Intel OpenCL FPGA Arria 10 devices on DevCloud?Solved2.1KViews0likes4CommentsOpenCL SDK Discontinuance Notice
When Going through the Getting started guide for OpenCL FPGA SDK, I have seen this Discontinuance Notice, I use OpenCL FPGA SDK to test Different Benchmark programs and try to optimize them, on DevCloud. Does this Discontinuance mean, its support will also be stopped on DevCloud?Solved1.8KViews0likes2Comments
