has anybody thought about building a vSMP system from ScaleMP? I´ve been thinking about building a Proof Of Concept, using a 2 2P boards (certified SuperMicro 2p boards) using a direct InfiniBand SDR connection between boards. tow of them cheap 8 core(magnycours) off feebay and just 2 vSMP foundation license($400 a piece).

test to see how good it scales(native vs vSMP PPD) anything more than 80% efficiency would be nice to create a 8P and beyond system, not to stay with the virtual 4P as a native 4P would be faster.

Keep us posted if you do this. I have seen many people ask if this is possible/worthwhile but have yet to see anyone go through with it.

Have the server up and running. thumb.gif
Looks very clean and installing the CPUs and memory was a breeze.
Yes the fans are loud but deep in the basement no one can hear them.
Now I have an issue with memory.
After the first CPU was installed with memory I verified that it had 8GB (4 x 2GB) on boot.
After that I did not pay close attention to the memory amount after each CPU installed.
Now that all is installed I'm only showing 28,xxxMB total installed.
Is there a simple method to determine which CPU(s) have less than 8GB available?
I have checked and none of the ram is running hot. Just seems two sticks have not been recognized.

You can go to the bios and see what nodes show up under memory settings. Also if you installed the TurionPowerControl you can check timings and verify all nodes. There might be other ways but Im a noob at this. I would reseat the memory again. That happened to me before.

Thanks. I'll take a look at the bios. I'm finishing the install of Ubuntu while I'm deciding how to troubleshoot the ram.
Just got too happy after the first CPU and sticks went in and failed to check the rest.
I did one group at a time just to be sure the system had no errors but missed which one had less ram. rolleyes.gif

Still looking the the ram issue.
But in the mean time I have the first WU folding. It's a 6901 with a TPF of 10:50.
I believe I forgot to put -bigadv in the startup line. thumbsdownsmileyanim.gif
I'll do a -oneunit after this one completes and update the start line.

I set the fah folder as shared so that I could monitor the status from a network PC.
The PC I use HFM on can see the remote folder just fine but the log files and all do not appear to be in there.
The only extra piece I installed so far was langouste.
Shouldn't FAHlog.txt be found in the fah folder?

You need to install Kraken for sure. Also, the fahlog.txt should be inside the fah folder. For HFM to get a reading from another computer you just need to point it to the HFM main folder.

You mean the fah main folder?
The Kraken is next on my list, after the ram fix.

Yes, sorry. No need to point it to the work one.
