The Hoard Scalable Memory Allocator
Hoard is a scalable memory allocator (malloc replacement) for multithreaded applications. Hoard can dramatically improve your application's performance on multiprocessor machines. No changes to your source are necessary; just link it in. Hoard scales linearly up to at least 14 processors. The supported platforms include Linux, Solaris, Mac OS X, and Windows NT/2000/XP/64.

Release Notes: This release incorporates a number of fixes and improvements: better per-thread allocation, improving speed for Unix platforms that do not support __thread; interception of the Solaris threads API (thr_*) to work with older Solaris programs; a fix for a possible race condition; and increased checking to protect against heap corruption or other errors. Hoard now uses GNU-supported hooks on platforms with glibc (especially Linux), allowing it to work better with legacy programs.

Release Notes: This release fixes a serious bug for Windows in thread reclamation. It fixes a small memory leak in thread creation. It substantially increases performance for small objects on 64-bit platforms. It works on 64-bit Windows.
- 19 Sep 2007 00:05
Release Notes: The fast path for allocation was streamlined, substantially accelerating both 32-bit and 64-bit code. pthread_* based thread-specific data is now used for x86-64, where it's faster. These combine to improve benchmark performance on x86-32 by up to 13%, and on x86-64 by up to 32%.
- 25 May 2007 09:53
Release Notes: This release has fixes for building on Mac OS X (Darwin) and to support some older versions of the Sun compilers. It adds FreeBSD as a supported target.
- 21 May 2007 20:47
Release Notes: An x86-64 target was added for Linux/GCC along with support for posix_memalign (for Unix systems), and a static library build option for Linux.

Red Hat 6.1 problem FIXED
Version 1.3.1 fixes the problem (a deadlock caused by a malloc call within atexit).
Red Hat 6.1 incompatibility
I've just learned that Hoard does not work with Red Hat 6.1 (it works with 6.0). The problem is in the version of libc. A workaround using the libc and libpthread libraries from the 6.0 distribution is described on the Hoard home page. I'll release a new version as soon as I find a workaround I can implement in Hoard.
Hoard update (oops)
Someone pointed out that I had unnecessary dependencies on
iostream.h (an artefact of debugging), so I removed them and updated the tarfile, but unfortunately didn't do a "make clean" before testing it -- a test program produced in the build requires iostream.h.
If you downloaded this version (that's around 20-40 people before I discovered the error), try the updated version (1.0.1).
Thanks,
Emery
