Tilera Releases 64-Way Chip Dev Tools
eldavojohn writes to tell us that Tilera has released a Linux-based development kit for their 64-core system on a chip. "The Tile64 is based on a proprietary VLIW (very long instruction word) architecture, on which a MIPS-like RISC architecture is implemented in microcode. A hypervisor enables each core to run its own instance of Linux, or alternatively the whole chip can run Tilera's 64-way SMP (symmetrical multiprocessing) Linux implementation. An 'iMesh' switching interconnect, developed by Tilera's founder, MIT professor and serial entrepreneur Dr. Anant Agarwal, is said to eliminate the centralized bus intersection that limited scalability in previous multicore designs."
As a consultant for several large companies, I'd always done my work on
Windows. Recently however, a top online investment firm asked us to do
some work using Linux. The concept of having access to source code was
very appealing to us, as we'd be able to modify the kernel to meet our
exacting standards which we're unable to do with Microsoft's products.
Although we met several technical challenges along the way
(specifically, Linux's lack of Token Ring support and the fact that we
were unable to defrag its ext2 file system), all in all the process
went smoothly. Everyone was very pleased with Linux, and we were
considering using it for a great deal of future internal projects.
So you can imagine our suprise when we were informed by a lawyer that
we would be required to publish our source code for others to use. It
was brought to our attention that Linux is copyrighted under something
called the GPL, or the Gnu Protective License. Part of this license
states that any changes to the kernel are to be made freely available.
Unfortunately for us, this meant that the great deal of time and money
we spent "touching up" Linux to work for this investment firm would
now be available at no cost to our competitors.
Furthermore, after reviewing this GPL our lawyers advised us that any
products compiled with GPL'ed tools - such as gcc - would also have to
its source code released. This was simply unacceptable.
Although we had planned for no one outside of this company to ever
use, let alone see the source code, we were now put in a difficult
position. We could either give away our hard work, or come up with
another solution. Although it was tought to do, there really was no
option: We had to rewrite the code, from scratch, for Windows 2000.
I think the biggest thing keeping Linux from being truly competitive
with Microsoft is this GPL. Its draconian requirements virtually
guarentee that no business will ever be able to use it. After my
experience with Linux, I won't be recommending it to any of my
associates. I may reconsider if Linux switches its license to
something a little more fair, such as Microsoft's "Shared Source".
Until then its attempts to socialize the software market will insure
it remains only a bit player.
Thank you for your time.
