GridGain + Multi-Core processors

GridGain is an open source product written in Java providing a grid computing platform. It is known to be one of the more widely used grid product, certainly, as far as I see, one of the easiest to "gridify" or grid-enable an existing product.

One of the applications of the product is to couple with Amazon EC2 to make a "cloud" computing platform. See Gridgain + Amazon EC2

The widespread use of "multi-core" PCs also means that the product can be used to "parallelise" to take advantage of this increased power.

My setup involves one "broker" node and three "worker" nodes. The grid job is sent from one of the worker nodes.

I use ActiveMQ for communication between nodes, GridSharedFsCheckpointSpi for saving down intermediate data (to be picked up during the "Reduce" phase) and JobStealing SPI for automatic load-balancing and failover.

Citigroup's Margolies to go it alone | FT

Submitted by cahn on 19 July, 2004 - 6:53pm

Ross Margolies, who runs $3.25bn for Citigroup in three different hedge funds, is quitting the bank this summer to set up his own hedge fund business.

The venture, yet to be named, is expected to be running by October.

Mr Margolies and his 50-strong team will still manage $3.25bn for the bank and have also made an arrangement to provide the bank with a "material" slice of future capacity in the new venture. The plan is to raise more assets in the coming months and set up new hedge fund products.

Mr Margolies, who runs arbitrage and equity strategies, joins the growing numbers of bankers who are quitting Canary Wharf and Wall Street to set up their own businesses in the fast-growing hedge funds sector.
