License clarification for code on 1024 cores

[Gopalakrishna Palem]

Hello Dmitry, came across your 1024 cores site and found the queues to be useful. 

On your site footer, it indicates the code as being BSD style, so downloaded the mpmc_block_queue code from downloads - but when opened the code inside the header it says 'GPL'.

Could you please confirm if the code could be used in BSD style license as indicated at: http://www.1024cores.net/home/code-license  It would be very helpful.

Thank you,

GK

Hi Gopalakrishna,

I've reuploaded mpmc_block_queue with BSD license:

While on this topic:

I have ported the MPMC queue implementation to Java. This relied heavily on the original, but the code is a complete re-write from scratch due to the differences in language concurrency support and memory layout. I have given credit and provided a link in the class docs but am unsure regarding the licensing...

Would you consider my code a modification of the original? Would you expect it to follow the same license?

The code is here: https://github.com/JCTools/JCTools/blob/master/jctools-core/src/main/java/org/jctools/queues/MpmcArrayQueue.java

Thanks (for your feedback and your invaluable website),

Nitsan

it's BSD licensed, so mentioning the original work is enough
you don't need to follow the same license
thanks
