Arash Sadeghi was arrested a number of times for participating in the demonstrations that followed the disputed presidential election in 2009. On 4 April 2010, Judge Pir-Abbas in Branch 26 of the Revolutionary Court sentenced him to 74 lashes and six years in prison after convicting him of the vaguely-worded national security charges of “gathering and colluding against state security” and “spreading propaganda against the system”. He was acquitted on appeal of the latter charge and his sentence reduced to one year imprisonment and four-years suspended sentence for the former. Arash Sadeghi’s current detention is unrelated to his previous case but it is believed that he is being held under suspicion of “gathering and colluding against state security”, although he has not been formally charged. No further details are known and the case is said to be “under investigation”, meaning that he cannot have access to legal representation.
On 3 June 2013, a debate on sex work was arranged by Solas, Centre for Public Christianity. The debaters were Laura Lee (Sex worker rights campaigner, blogger and sex worker), Douglas Fox (of theInternational Union of Sex Workers, editor of the blog Harlots Parlour and sex worker), Rhoda Grant MSP (who has put forward a Bill to criminalise sex purchase in Scotland) and Richard Lucas (a minister and member of Solas – you can read his blog here). Laura Lee and Douglas Fox were debating against Richard Lucas and Rhoda Grant.
The debate opened with a statement by each of the panel. Laura Lee told her story of how she was working as an independent escort when a member of the community outed her on “every social media platform they could find”. She and her 7 year old daughter were bullied, her car was vandalized and her daughter was told by a well-respected, churchgoing adult man that her mother “will die of AIDS” – a statement which caused the child to panic as she believed it. A paedophile who had returned from a long prison sentence for molesting children was accepted by the same community.
Rhoda Grant’s main points were that “demand is met by coercion” and sex work is “trafficking”, not free choice. Ms Grant confused sex work with paedophilia and child abuse. She used Syrian women to back up her argument which isn’t relevant to her Bill as its scope is UK-limited.
Laura Lee took offence to Grant’s use of the term “prostituted women”. Laura said “It suggests we can’t consent to sex because we’re not there of our own free will. But we can, just like a barman can refuse to serve a customer.” She said that clients have reported incidents of violence towards sex workers to Crimestoppers and that the Ugly Mugs scheme which protects sex workers by creating a database of violent clients is now at risk due to funding.
LANL has always been an early adopter of transformational high performance computing (HPC) technology. For example, in the 1970s when HPC was scalar; LANL acquired the first Cray-1 vector supercomputer. When HPC was vector; LANL acquired the first TMC CM-5 massively parallel supercomputer; the first #1 on the TOP500 list. In the 2000s, HPC was distributed memory; LANL and IBM built Roadrunner, the first hybrid supercomputer and the first supercomputer to attain a sustained petaflop/second.
Roadrunner Open Science: important strides taken
Open Science (unclassified work) on Roadrunner, the world’s first petaflop/s computer, resulted in significant breakthroughs in materials, astronomy, and laser plasma science. Presented here are images, movies, and brief explanations of the exciting new work done on Roadrunner by seven Principal Investigators (P.I.s):
Roadrunner was a supercomputer built by IBM at the Los Alamos National Laboratory in New Mexico, USA. The US$100-million Roadrunner was designed for a peak performance of 1.7 petaflops. It achieved 1.026 petaflops on May 25, 2008 to become the world’s first TOP500 Linpack sustained 1.0 petaflops system. It was unique because the computer was built from off the shelf parts, with many novel design features including the first hybrid computer built at the supercomputing scale.
In November 2008, it reached a top performance of 1.456 petaflops, retaining its top spot in the TOP500 list. It was also the fourth-most energy-efficient supercomputer in the world on the Supermicro Green500 list, with an operational rate of 444.94 megaflops per watt of power used. The hybrid Roadrunner design was then reused for several other energy efficient supercomputers. Roadrunner was decommissioned by Los Alamos on March 31, 2013. In its place, Los Alamos uses a supercomputer called Cielo, which was installed in 2010. Cielo is smaller and more energy efficient than Roadrunner, and cost $54 million.
