Hi Yutong,
I wrote the wrong number of tasks, it's 50000 not 5000.
Also after checking HPC logs, my team found out that there was an internal error which is related to SQL server used to power HPC cluster.
We're using HPC Pack 2016 SP 2 with SQL Server Express on Head Node.
The error we got is: HPC Scheduler The query processor ran out of internal resources and could not produce a query plan. This is a rare event
and only expected for extremely complex queries or queries that reference a very large number of tables or partitions. Please simplify the query. If you believe you have received this message in error, contact Customer Support Services for more information
I believe that there is no way we can't change the SQL query inside HPC cluster.
Is there any way to address this issue?
