Compucon CPD Seminar
Bullets and Waves
The famous physicist Richard Feynman used bullets and water waves to demonstrate the behaviour of electromagnetic waves (which include light) some 50 years ago in his lectures. He described high frequency waves such as X-ray and Gamma ray as bullets and low frequency waves such as Wi-Fi and radio as waves. His teaching has presumably triggered the use of wave interference to observe objects in the sky very far away as Dr Ensor of New Zealand SKA project leader showed us in his speech in Tech Briefing of June 25. This session will attempt to reveal the magic of nature which allows us to see whatever we could not see otherwise. A bit of mathematical background is desirable but not essential for enjoying this session. This session will show us how we can apply computing to reach new frontiers (of vision, knowledge and business).
PC Platform Connectivity
We mentioned PC Platform connectivity twice in the Tech Briefing event. One is about an upcoming new standard called SAS3 which may speed up computer performance by a factor of two depending on where the bottleneck is. The other is about PCIeV3 which rendered GPU not economical for use in SKA signal processing. These 2 standards are among a host of technologies that will keep PC on the desktop and in the local server room for many years to come. This session will be a review of PC platform connectivity and this will allow us to develop and specify system platforms to provide maximum performance to our clients for defined tasks without wasting any resource. The last phrase means fitness for purpose and lowest cost of ownership.
Intel Core (Draft)
We have evolved our Compucon WGS from Intel 3G to 4G Core processors in late June. We will explain how 4G performs better than 3G in this session. We will evolve Superhawk to 4G as soon as Intel has released Core i3 because 15% of our customers ordered Core i3 which is fit for purposes. The evolution is not painless as the CPU interface has 1155 pins for 3G and 1150 pins for 4G and there is a small price premium too. What benefits should we expect? How would Superhawk 4G compare with Diamond (3G) and Thunderbird (AMD APU)?
SSD as a HDD cache or HDD supplement or replacement has gained momentum for performance reasons. The price of SSD is still much higher than HDD and therefore we do not see SSD replacing HDD in a hurry. While performance is the appeal of SSD, the longevity of SSD is still a concern due to its short history of mainstream use. For peace of mind, there are indeed SSD models that are designed to be more reliable and longer operating life than others. We call them Server grade SSD. On the performance front, PCIe SSD is becoming more common and we shall look into this category too.
