Philip Hyunsu Cho	ea850ecd20	[CI] Refactor Jenkins CI pipeline + migrate all Linux tests to Jenkins (#4401 ) * All Linux tests are now in Jenkins CI * Tests are now de-coupled from builds. We can now build XGBoost with one version of CUDA/JDK and test it with another version of CUDA/JDK * Builds (compilation) are significantly faster because 1) They use C5 instances with faster CPU cores; and 2) build environment setup is cached using Docker containers	2019-04-26 18:39:12 -07:00
Andy Adinets	b833b642ec	Improved multi-node multi-GPU random forests. (#4238 ) * Improved multi-node multi-GPU random forests. - removed rabit::Broadcast() from each invocation of column sampling - instead, syncing the PRNG seed when a ColumnSampler() object is constructed - this makes non-trivial column sampling significantly faster in the distributed case - refactored distributed GPU tests - added distributed random forests tests	2019-03-13 12:36:28 +13:00

[CI] Refactor Jenkins CI pipeline + migrate all Linux tests to Jenkins (#4401 )

* All Linux tests are now in Jenkins CI
* Tests are now de-coupled from builds. We can now build XGBoost with one version of CUDA/JDK and test it with another version of CUDA/JDK
* Builds (compilation) are significantly faster because 1) They use C5 instances with faster CPU cores; and 2) build environment setup is cached using Docker containers

Improved multi-node multi-GPU random forests. (#4238 )

* Improved multi-node multi-GPU random forests.

- removed rabit::Broadcast() from each invocation of column sampling
- instead, syncing the PRNG seed when a ColumnSampler() object is constructed
- this makes non-trivial column sampling significantly faster in the distributed case
- refactored distributed GPU tests
- added distributed random forests tests
