Applications and Porting / Re: [DEV] Using Java's Vector API on PPC64LE

I agree that it would likely have to be IBM to sponsor such a project.

Hardware, developers, QA, Project management, documentation, etc would be significant.
Could AIs help reduce the cost or cut time lines? Possibly.

I imagine such a team would take several quarters to produce something nearing an Alpha, productizing several quarters more.

Thinking out that timeline, we'd be in to Power11's life cycle, potentially the Solid Silicon chip would be real as Power10 compatible. The market will have further moved into AArch64, with RISC-V maturing towards early viable production systems. PPCs continue in their markets with constant shrinkage due to migrations. I guess it becomes a long term question - Does IBM have plans for Power 12/13/14 bringing the ecosystem through the 2030s? What is the plan to build development resources for the road map?

Perhaps I'm heading into discussion points for another part of the forum.


From my point of view the low hanging fruit is getting Java based applications to work nicely on POWER. My focus has been on Apache CXF, ActiveMQ, Camel, Karaf, Kafka - effectively SOA style services that business use in integration stories. POWER has a place in that ecosystem given its performance characteristics under load.

The core team doesn't seem to be interested in having it supported:

No idea how large a project making a fork would be; assumption is that its a very large porting effort.

Thanks 

If you have any suggestions for future Java on PPC64LE videos please feel free to share - my youtube feed feels devoid of content at times

Applications and Porting / [DEV] Using Java's Vector API on PPC64LE

Wanted to share this video I made on our experiences with Java's Vector API (incubating) on PPC64LE:
https://www.youtube.com/watch?v=auqYQdul52k

Its a mixed bag at this point in time - some workflows benefit, while some others do not.

The implementation of Vector API is x64/AArch64, with allowances to let other architectures provide implementation in the future. Perhaps this video will help encourage JVM implementations to address the shortfall.

Applications and Porting / Running Ollama on PPC64LE

« on: February 18, 2025, 11:11:59 am »

After reading the great post on VivaPowerPC about running Ollama on PPC64LE, I got excited and made a video following their steps, and the results I got on my Raptor Blackbird (yes, there is a shout out to VivaPowerPC for their excellent article). Wanted to share a link with the community

Has anyone else run Ollama on their PPC64LE rigs? Have benchmark results to share?
If I can get another RTX A1000 (PCIe x8) card I'll see if i can get the Nvidia ppc64le drivers to work with Ollama.

Applications and Porting / [DEV] How we use a Raptor Blackbird to improve PP64LE support on Apache Projects

Hi All,

Long time reader, first time poster.
I wanted to share a video we made about how we use a Raptor Blackbird to help improve PPC64LE support on Apache Projects.
Although the projects are written in Java, there are still many edge cases where one needs to tweak code to support PPC64LE platforms.

Over the last year of using this machine, I've come to truly appreciate its raw power, and look forward to making more content featuring it as a runtime.
