hello,
i have problem with vmware esx server.

i installed matlabe on vm with ubuntu-10.10 installed (with 16GB of RAM, 2CPU, 300GB of HDD)

Developers are saying their Desktop's with "i3 Processor" matlab installed are performing well


Can any body give me solution

Thanks,

What's the question and issue?
Robin CMSenior Security and Infrastructure Engineer

I assume you mean "are not performing well"?
What is the spec of your ESX host and storage (local, iSCSI, FC, link speed, number of drives and RAID type)?
Do you have the VM tools installed in the guest?

I think you are trying to say that running Matlab from your Ubuntu VM is not performing as well as it does when ran from i3-based desktops???  if so, it might be related to the module you are using in Matlab as some are fairly graphical in nature and VM's don't have much in the way of a graphics processor like your desktop's do.  You can try increasing the amount of video ram that the VM is using.

Otherwise, use the the performance charts within the vsphere client to check that VM's usage of memory, processor and disk.

please let us know if we're understanding you correctly and more details about the VM's configuration and problems.

If you are having issues with VM performance when compared to their i3 Processor Desktops, why are you trying to virtualise a Developers Desktops? Not all computers are suitable candidats for virtualisation.

The Best Developers Desktop is a Physical PC, not a virtualised PC.
Commented:
Your physical machine running mathlab use the gpu to process screen write.
Vmware use the cpu to do that. which is slower

video acceleration don't work yet on esx based server
have you tried vmware workstation which is desktop oriented?

that's because your question wasn't clearly illustrated.

These forums work best when the author takes the effort to work with the various experts to arrive at the best solution/answer.

You would be better using VMware View to create workstations and using PCoIP.

But it does depend on what DirectX GPU Functions are being used by Matlab from your Ubuntu, and VMware View is only Windows Desktops.
