RFR: 8139272: Add configure variable to set concurrency for jtreg tests (original) (raw)

Hi all,

this patch adds a new configure variable: --with-test-jobs. The new variable configures how many tests jobs we run concurrently (aka the -concurrency flag to JTReg). Today --with-jobs is passed as the -concurrency flag to JTReg which most likely is too big for most systems with many cores.

For hotspot, the only "supported" configuration for running the jtreg tests is with -concurrency:1. However, most machines will run the tests successfully with more concurrency, but I used a default of 1. For the JDK tests I kept --with-jobs as the default concurrency since I want to keep the old behaviour.

Enhancement: https://bugs.openjdk.java.net/browse/JDK-8139272

Thanks, Erik
