A reminder to non-pet owners
by paul on Jul.28, 2010, under Humor, Pets
For all those non-pet owners who like to visit our house, I would ask that you please remember these simple rules:
- They live here. You don’t.
- If you don’t want their hair on your clothes, stay off the furniture. That’s why they call it furniture.
- I like my pets a lot better than I like most people.
- To you, they are animals. To me, they are adopted sons & daughters who are short, hairy,walk on all fours and don’t speak clearly.
The 48-core SCC processor: the programmer’s view
by paul on Jul.23, 2010, under Computing
The number of cores integrated onto a single die is expected to climb steadily in the foreseeable future. This move to many-core chips is driven by a need to optimize performance per watt. How best to connect these cores and how to program the resulting many-core processor, however, is an open research question. Designs vary from GPUs to cache-coherent shared memory multiprocessors to pure distributed memory chips. The 48-core SCC processor reported in this paper is an intermediate case, sharing traits of message passing and shared memory architectures. The hardware has been described elsewhere. In this paper, we describe the programmer’s view of this chip. In particular we describe RCCE: the native message passing model created for the SCC processor.
Must have been a great sabbatical – just finished this paper for Supercomputing 2010, and it was the least painful paper I’ve ever written.
Keeping Portland Weird

| We were in Portland over the weekend, and look what we saw -- 8000 naked Portlanders out for a ride as part of the World Naked Bike Ride. This makes the Portland event about eight times bigger than the equivalent London event -- wow! |
