[jira] [Updated] (YARN-9265) FPGA plugin fails to recognize Intel
Processing Accelerator Card
[ https://issues.apache.org/jira/browse/YARN-9265?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Peter Bacsko updated YARN-9265:
-------------------------------
Summary: FPGA plugin fails to recognize Intel Processing Accelerator Card (was: FPGA plugin fails to recognize Intel PAC card)
> FPGA plugin fails to recognize Intel Processing Accelerator 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
> Priority: Critical
>
> 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.
>
> DIAGNOSTIC_PASSED
> --------------------------------------------------------------------
>
> Call "aocl diagnose <device-names>" to run diagnose for specified devices
> Call "aocl diagnose all" to run diagnose for all devices
> {noformat}
> The plugin fails to recognize this and fails with the following message:
> {noformat}

> Problem #2
> The plugin assumes that the file name under {{/dev}} can be derived from the "Physical Dev Name", but this is wrong. 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}}.
