Full Changelog: v1.3.0...v1.3.1

Task Spooler 1.3.0 Release

Release Notes

Internal changes

• GPUs are assigned to clients instead of being selected as before. Thus, queued jobs are executed immediately if there are enough GPUs and slots. As a result, the two flags --set_gpu_wait and --get_gpu_wait are redundant and will be removed in the next major release.

New features

• Log name and log folder can be changed via command lines (#7).
• Environment variables in server side can be seen and modified via --getenv, --setenv and --unsetenv.
• Let only specific GPUs be visible to ts server via TS_VISIBLE_DEVICES (must be set before starting ts for the first time or via --setenv).
• Let users decide the availability of GPUs by setting the free memory percentage via --get_gpu_free_perc and --set_gpu_free_perc.
• More human readable representation for time in -i.

Stability enhancements

• Free malloc'ed memory (#13).
• Fixed a bug that does not pass the error message from server when using -i.

Task Spooler 1.2.1 Release

Release Notes

Overview

• Installing scripts are cleaned up and renamed.

Task Spooler 1.2 Release

Release Notes

Overview

This release strides towards stability.
Various bugs and cleanups are addressed in this release.
For more details, please see the Changelog.

Bug Fixes

This release fixes a bug described in #2. This issue is that a task status changes to running but output shows (...) because the client sleeps multiple times due to this bug, and it happens programmatically when consecutive GPU jobs are scheduled too soon one after another. This bug is fixed here by making sure the client sleeps only once.

Cleanups

Minor cleanups and bug fixes are pushed including various refactorings and memory freeings.

Updates

Man page is finally updated.
