Subject: [PATCH 0 of 3 V3] libxc: checkpoint compression
Date: Thu, 13 Oct 2011 16:47:51 -0700 [thread overview]
Message-ID: <patchbomb.1318549671@athos.nss.cs.ubc.ca> (raw)
This patch series adds checkpoint compression functionality, while
running under Remus.
Tested under xen-4.2-unstable.
A simple benchmark: SpecJBB (Java Benchmark)
- 4 minute Remus run, with PV domU (2.6.32 xenolinux kernel), 1G memory and 2 VCPUs
- Data sent without compression: ~70GB.
- Data sent with compression: ~8GB.
Changes since last version:
1. A revised compression stream format
2. Changed the xc_remus_* interface to a generic xc_compression_* format
3. Fixed issues like unaligned access, missing bounds check, etc
4. General code cleanups.
