Peter Bacsko created YARN-9265: ---------------------------------- Summary: FPGA plugin fails to recognize Intel PAC card Key: YARN-9265 URL: https://issues.apache.org/jira/browse/YARN-9265 Project: Hadoop YARN Issue Type: Sub-task Affects Versions: 3.1.0 Reporter: Peter Bacsko
The plugin cannot autodetect Intel FPGA PAC (Processing Accelerator Card). There are two major issues. Problem #1 The output of aocl diagnose: {noformat} -------------------------------------------------------------------- Device Name: acl0 Package Pat: /home/pbacsko/inteldevstack/intelFPGA_pro/hld/board/opencl_bsp Vendor: Intel Corp Physical Dev Name Status Information pac_a10_f200000 Passed PAC Arria 10 Platform (pac_a10_f200000) PCIe 08:00.0 FPGA temperature = 79 degrees C.

This is not the case. For example, it thinks that the device file is {{ /dev/pac_a10_f300000}} which is not the case, the actual file is {{/dev/intel-fpga-port.0}}. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
