NASA's Pleiades Studies Impact of Asteroid Hitting Earth

NASA's Pleiades Studies Impact of Asteroid Hitting Earth
NASA is using its Pleiades supercomputer to simulate the damage asteroids can cause if they crash into Earth. According to a case study on nasa.gov, the goal is to better assess the threat of collisions and help develop mitigation strategies, such as evacuating populations, altering an asteroid's trajectory so it misses Earth, or destroying the object in space. An asteroid larger than 30 meters, or 98.4 feet, in diameter is expected to hit our planet every 100 years; there are roughly 10,000 of those near Earth, 1,600 of which are classified as dangerous.

Supercomputers Eyed for Clean Energy Technology

Supercomputers Eyed for Clean Energy Technology
The Department of Energy has launched a program that allows private industry to use high-performance computing systems at the Lawrence Livermore, Lawrence Berkeley and Oak Ridge national laboratories to develop new clean energy technology. The initiative, called High Performance Computing for Manufacturing Program (HPC4Mfg), is designed to foster public-private research and development projects to bolster US competitiveness in clean energy manufacturing, according to a recent press release by Lawrence Berkeley National Laboratory (LLBL). The DoE will provide an initial $5 million to fund 8 to 10 projects for up to a year. The new software tools, combined with the supercomputer, helped the researchers identify several dozen potential genetic modifications that could reduce drug toxicity, according to a university release.

Supercomputer Unlocks Mutant Cancer Secrets

Supercomputer Unlocks Mutant Cancer Secrets
Scientists have discovered how genetic cancer mutations attack the networks that control human cells, a finding that could lead to the development of more-precise, personalized cancer treatments. University of Copenhagen researchers, along with counterparts at Yale, Zurich, Rome and Tottori, have developed software that computationally translates the effects of cancer mutations on the function of proteins in individual patients. This can unravel how disease mutations target and damage the protein-signaling network inside human cells.

5 Tips for Speeding Up Your Code Using TBB

5 Tips for Speeding Up Your Code Using TBBShare your comment!

Intel Threading Building Blocks is a library to help your application use parallelization without you having learn all the subtleties of threading and to avoid the pitfalls. If you use TBB to speed up your software, below are a few tips to help you on your way.

You don’t always need a blocked_range

A blocked_range in TBB is a template class that’s used to divide (recursively) an array or range of data into smaller pieces so that TBB can then process each piece concurrently. However, you can use TBB to control how the division is done. You have to provide a simple class D that implements these methods:
  • bool empty() const;
  • bool is_divisible() const;
  • D (D & d, split);
The empty() function returns true if the range is empty, while is_divisible() returns true if the range can be split into two non-empty sub-ranges. The constructor D has a parameter d of type D and a constant of type tbb::split. After splitting the range into two roughly half ranges, d refers to the first half and the constructed object instance to the second half.
The advantages of this are that you’re free to partition the range as you choose. For example, if you are processing image data, then a 2D array of pixels could be processed.

Use parallel_do

The traditional do_while loop has never been what you’d call a popular construct compared to while and for loops. In my opinion the do_while loop was a design mistake in C, C++ and other C related languages. If you compare do_while to Pascal’s Repeat_Until, both are similar and run the statement at least once then check loop termination at the end. however repeat-until(done) terminates in the more logical but opposite sense to do_while(!done) and I think repeat_until is clearer. Especially as in northern England the word while is sometimes used to mean until! “He were there while 11:00 pm”.
In TBB, you can a tbb::parallel_do when the loop terminating condition isn’t predetermined as it would be with a tbb::parallel_for. An additional advantage of parallel_do is that a second parameter of type parallel_do_feeder can be used to add additional work items.

Use Concurrent Containers

The C++ STL containers are broadly thread safe. Simultaneous reads of the same object are safe and simultaneous writes of different objects. Simultaneous writes to the same objects will however probably cause data races and lead to corruption of the STL container.
But Intel TBB to the rescue. It provides several concurrent container template classes, specifically concurrent_hash_map, concurrent_vector and concurrent_queues. Locking is done only on the part of the container is needed but this means that overall performance is a bit slower than STL containers so only use these if a speedup is likely.

Avoid false sharing with cache_aligned_allocator

False sharing is where two or more processes access the same shared memory cache line at the same time. Modern processors read data from memory not just a byte, word or quadword at a time but in a fixed size block called a cache line. When false sharing occurs, reading data into a cache line causes the other processor’s cache line data to become stale and it requires a refresh which diminishes performance.
Intel TBB provides two allocator templates classes similar to std::allocator. If your program does a lot of memory allocation then you would use the scalable_allocator, but to avoid false sharing you’d instead use the cache_aligned_allocator. Two objects allocated by this are guaranteed not to have false sharing.

Use Tasks Not Threads

In the .NET world, the Task Parallel Library has made multi-tasking a lot simpler than managing threads and with Intel TBB you have the equivalent for C++. Thread programming can be messy and very easy to get wrong. If you develop tasks instead then you let the task scheduler allocates tasks to threads, and tasks start up can be up to 100x faster than threads on Windows.
It’s worth reading the Catalog of Recommended task patterns to understand how best to use tasks.

Conclusion

Hopefully, these tips will give you a flavor of TBB’s power and how you can get the most out of it.
