lmbench-3.0-a4 released

This is primarily a bug-fix release. Some buggy areas that were cleaned up include:
- 32bit vs. 64bit architecture issues
- automatic memory sizing and size detection
- per timing interval initialization/cleanup
- lat_mem_rd strided and random memory access patterns
- lat_mem_rd memory size now grows exponentially instead of linearly
- lat_ops / par_ops are now more accurate on more architectures
- stream used the wrong kernel in one instance
- automatic configuration of random number generators
- potential infinite loop in timing harness... read more

This is the first alpha release of the developer branch, lmbench version 3.0. It includes a large number of new features, such as the ability to measure performance under scalable load, and new benchmarks such as tlb (# of TLB entries), line (cache line size), stream (lmbench version of John McCalpin's STREAM benchmark), lat_usleep, lat_ops (add/mul/div latency for int/uint64/float/double), par_mem (memory subsystem instruction-level parallelism), par_ops (instruction-level parallelism for many basic operations), and several others.

lmbench-2.0 patch1

I just released the first patch for lmbench-2.0,
which fixes a bug in the summary result report

lmbench-2.0 release

lmbench-2.0 has finally been released. I ran out bugs to fix, so I decided to call version 2.0 done.

Work has been progressing on lmbench-3.0, and the first alpha releases should start hitting the net in the not-too-distant future... lmbench3.0 includes new benchmarks, such as par_mem which measures the available parallelism in the memory heirarchy, and new capabilities for measuring system scalability by running benchmark processes in parallel in a controlled fashion.

lmbench-2beta1 has just been released. It contains several bugfixes and updated documentation. If you are running an alpha release, it is important to update to 2beta1.

lmbench-2alpha12 has been released. This should be the last alpha release for version 2, and is the first patch release in nearly two years.
