[jira] [Comment Edited] (MESOS-8038) Launching GPU task
sporadically fails.
[ https://issues.apache.org/jira/browse/MESOS-8038?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16193021#comment-16193021 ]

-----------------------------------------------------------------
[~bmahler] Attached the logs for master and slave.
For more context, when a large number of tasks (10-20) are launched, this problem occurs always.
When the framework launches job, with lesser number of tasks(1-6), it works fine or occurs very rarely. All the tasks are gpu based.

> Key: MESOS-8038
> URL: https://issues.apache.org/jira/browse/MESOS-8038
> Project: Mesos
> Issue Type: Bug
> Components: allocation, gpu
> Affects Versions: 1.4.0
> Reporter: Sai Teja Ranuva
> Priority: Critical
> Attachments: mesos-master.log, mesos-slave.INFO.log
>
>
> I was running a job which uses GPUs. It runs fine most of the time.
> But occasionally I see the following message in the mesos log.
> "Collect failed: Requested 1 but only 0 available"
> Followed by executor getting killed and the tasks getting lost. This happens even before the the job starts. A little search in the code base points me to something related to GPU resource being the probable cause.
> There is no deterministic way that this can be reproduced. It happens occasionally.
> I have attached the slave log for the issue.
> Using 1.4.0 Mesos Master and 1.4.0 Mesos Slave.
