why FPGA reserved some resources when using opencl
Hi intel team, When compiling an empty code using opencl on intel FPGA, I noticed that some resources are reserved. Such as 40,650 ALUTs (9%), 52,976 FFs (6%), and 283 RAM blocks (11%) reserved and not available for use. I need to know why they are reserved ??? for what goal ??1.8KViews0likes3CommentsHow to determine the <device_name> <aocx_file> for FPGA card
Dear intel team, When typing <aocl diagnose> command. The following sub-message appeared. <BSP not loaded for Programmable Accelerator Card pac_f000000 * Run 'aocl diagnose' to determine device name for pac_f000000 * Run 'aocl program <device_name> <aocx_file>' to initialize BSP> I want to Know how I can exactly determine device name and aocx_file. in order to load BSP. Bellow is the whole message: Using the following location for ICD installation: /etc/OpenCL/vendors Found 2 icd entry at that location: /etc/OpenCL/vendors/Intel_FPGA_SSG_Emulator.icd /etc/OpenCL/vendors/Altera.icd the following OpenCL libraries are referenced in the icd files: libintelocl.so libalteracl.so checking LD_LIBRARY_PATH for registered libraries: WARNING: libintelocl.so NOT FOUND libalteracl.so was registered on the system at /glob/development-tools/versions/fpgasupportstack/d5005/2.0.1/inteldevstack/hld/host/linux64/lib Using the following location for fcd installations: /opt/Intel/OpenCL/Boards Found 1 fcd entry at that location: /opt/Intel/OpenCL/Boards/dcp_bsp.fcd the following OpenCL libraries are referenced in the fcd files: /opt/intel/2.0.1/inteldevstack/d5005_ias_2_0_1_b237/opencl/opencl_bsp/linux64/lib/libintel_opae_mmd.so checking LD_LIBRARY_PATH for registered libraries: /opt/intel/2.0.1/inteldevstack/d5005_ias_2_0_1_b237/opencl/opencl_bsp/linux64/lib/libintel_opae_mmd.so was registered on the system.

Hi @BoonBengT_Altera Thanks for your reply. I am not sure what do you mean by " by any chances did you managed to source the relevant opencl resource with source command? After sourcing would suggest to run a aocl diagnose to confirm device name installed." ?? Could you clarify more please ?? However, I attached the Makefile that I used. Please reply as soon as possible. Thanks,5.8KViews0likes0CommentsRe: How to resolve : Unable to get device ID
Hi @BoonBengT_Altera I attached a screenshot for the process. It is include the node, commands, and the error message. Please let me know if you need additional information since I really need to fix this issue as soon as possible. Thanks,5.8KViews0likes0CommentsHow to resolve : Unable to get device ID
Dear intel team, When trying to compile my host code today. I got this error message "Unable to get device_id ". This error message is part of my code. It is strange because yesterday, I didn't get this error message. See these lines of code plz: cl_platform_id fpga_paltform = NULL; if (clGetPlatformIDs(1, &fpga_paltform, NULL) != CL_SUCCESS) { printf("Unable to get platform_id\n"); return 1; } cl_device_id fpga_device = NULL; if (clGetDeviceIDs(fpga_paltform, CL_DEVICE_TYPE_ALL, 1, &fpga_device, NULL) != CL_SUCCESS) { printf("Unable to get device_id\n"); return 1; }6KViews0likes10Commentshost: acl_mem.c:394: acl_bind_buffer_to_device: Assertion `mem' failed.

Dear intel team, when compiling the host code using Make command. No errors appears. But when typing the ./host command. The following error showed up. I am not sure what this mean and how to fix it. Error: host: acl_mem.c:394: acl_bind_buffer_to_device: Assertion `mem' failed. Aborted1.4KViews0likes4Comments
