I've showed you link where Linux devs says Bonwick (from SUN) does FUD. That's enough.
Basically SMP is one big server with as many as 64 cpus. IBM AIX and HP-UX and Solaris servers are SMP servers with 64 cpus. IBM biggest Unix box, has only 32 POWER7 cpus because IBM AIX does not scale well enough in SMP servers.
HPC is a large cluster (a network with lots of PCs) and Linux scales very good on a cluster. There are large clusters, for instance SGI Altix server with 1024 cores. But it is easy to scale on a cluster.
When people say Linux scales bad, they are refering to SMP servers that are used in the Enterprise. There are no big SMP servers running Linux successfully. There are only Linux clusters in the market today.
Even Linux scaling experts from RedHat, etc said that Linux scales very well in a cluster (for instance, Google has 10.000 nodes in a network) but they also admitted that Linux scales bad on SMP servers. They said "the true strength of Linux is horizontal scaling" and they talked about Google's big cluster. You want to see the article by the Linux scaling experts from RedHat, and other Linux companies?
Why are there no big SMP Linux servers on the market? Because Linux scales bad on SMP servers. The SMP server market belongs to Enterprise Unix: AIX, Solaris, HP-UX, IBM Mainframes, etc.
I showed you papers. Even in this thread. You claimed lots of things, most of it were lies.
Are you able to point to that? Maybe I meant it scales to 64 CPUs, but then it sucks?
"...Solaris can scale only up to 64 physical CPUs on a single machine while Linux can scale up to 4096 physical CPUs. I don't care about hyper threading etc. I also don't care I could buy a [Solaris] 106 CPUs server years ago and I don't care how many threads Solaris sees..."
Nope, but saying Linux doesn't scale makes you a lier and FUDer. You've never gave any papers showing that Linux doesn't scale.
If Linux scales well on a SMP server, as you claim: show me a big Linux SMP server that is sold on the market. SMP servers are traditionally for Enterprise use and they cost very much. For instance, IBMs AIX server P595 costed 35 million USD when they got the TPC-C record earlier (until Oracle took the record). If Linux scales good on a single huge server, then everyone should buy cheap Linux SMP servers instead of forcing to buy expensive gear from IBM, HP, Oracle. So, where is the Linux SMP servers with 32 cpus? Show me. There are none. Why?
Haha, but I wanted papers which backup your claims. You were FUDing and lying a lot thus I was asking for papers.
You're still lying, because I don't pretend I don't see the paper. While I was talking about sdc this sounds strange.
This time you made some little research.
