Computer Setup for GOODS Science Demo at JBO 01/03
System Requirements
So that we can see where the requirements are coming from, and so resolve conflicts between them, let us try a matrix approach (MCH):
| | RAM | Disk | CPU | Display | Operating System/Platform | Network |
| ACE Client | 256+ | 10 GB+ | 500M+ for quick UI | 1024x768 | Java 1.4+ (1) | low (if using GOODS) can work offline with locally installed ACE |
| ACE Server (wrapper) | 256+ | low | 10 GB+ | n/a | Java 1.4+ (1) | high (need to copy in images) can work offline |
| ACE Server (SExtractor) | 256+ | low | 10 GB+ | n/a | Linux/Solaris; old ver available for Windows | none |
| Aladin | 256+ | <1Mb </td> | high | 1280x1024 | Java 1.1, 1.2, 1.3 | high (need to copy in images) |
| SED Tool | 10 | 1 MB | 750MHz | 800x600 | JDK 1.1+ | none |
(1) Java 1.3 and 1.4 are available on Windows, Linux, Solaris.
- 1 GB RAM OK
- 20 GB disk space is this enough? _OK_ * No, 200 GB please (minimum 100GB) <-- what drives this? Is this for each machine? (MCH)
- display resolution >= 1280*1024 pixel for monitor OK
- display resolution >= 1280*1024 pixel for beamer will probably need to hire one unless anyone can lend one
- Windows XP for core demo machine OK
- investigate use of JBO Linux machines for tutorial OK, these will be networked, please let Anita/Ant know what software is required
- Aladin has some problem in the "load" windows with jdk1.4.1
* use JVM 1.3, or the VM packaged with Aladin
- Demo machines: need 500-1.5GHz. Memory: things run best with >=1 GB RAM, but it works also with 512 or 256 MB
questions
- Is Solaris OK for the rest of the demo software for tutorial machines - we have some linux, some unix - , or should it be linux only, and if so is there any version restriction?
* Linux only please, because multiple configurations will
mean multiple problems.
* A single distribution of Linux for simplicity, with a
single window manager (KDE preferred)
- Can the software (including Aladin demo version) be held locally on our system or must it be on each machine separately? (normally all our software is installed and maitained centrally)
* Aladin can be installed centrally for the linux network,
but it must be tested.
Network
- Aladin functions off-line after ~30 sec network timeout at startup
* use the "-local" switch to avoid this timeout
(it's in the FAQ)
* also SED and ACE work off-line
- for on-line tutorial a bandwidth of >= 1Mbit/s/demo_station is desirable, but datasets with reasonable download time should be preselected and described here.
Resources available
- Some Linux, some Solaris
- Network:
- Bandwidth ??
- Likely load by others on the day ??
