Smalltalk 01/2010 - Virtual
by admin on Feb.16, 2010, under Smalltalk
Ok, the next image is ready. This image is now running under Debian 5 and when asked for a user you may enter the user name “smalltalk” with password “smalltalk”.
The following Smalltalks are installed:
* Smalltalk/X 5-4-6 (Windows)
* Smalltalk/X 5-4-6 (Linux)
* VASmalltalk 8.01 (Linux)
* VASmalltalk 8.01 (Windows)
* ObjectStudio 8.1 (Windows) - to show the problems with menus
* VisualWorks 7.7 (Linux)
* VisualWorks 7.7 (Windows) - to show the problems with menus
On the Desktop you find icons to start each Smalltalk. Before using VASmalltalk 8.01 you must start the emsrv server. The Linux and Windows version of VASmalltalk are working against the same emsrv server.

OpenCL API wrapper for VASmalltalk
by admin on Feb.03, 2010, under Smalltalk
After working on my primitive project I start having a closer look to OpenCL - a computational environment for graphics cards. Both comapnies - ATI and Nvidia - are offering support for OpenCL 1.0 on their graphic cards. But not on all cards. Nvidia has offering longer support for this - but was/is named Cuda.
With OpenCL you are able to run programs in parallel on graphic cards. OpenCL is both: an environment or API and a programming c-like language.
The OpenCL wrapper for VASmalltalk should become a wrapper for the OpenCL-API and is under development und available from vastgoodies. The state of today is, that you can now query your available platforms (ATI oder NVidia) and the available devices (CPU or GPU).
Actually it can deliver an system report output via:
| anInterface aStream | anInterface := MSKOpenCLInterface new initialize. aStream := WriteStream on: String new. anInterface allPlatformInfos do: [ :eachPlatform | eachPlatform printReportOn: aStream ]. aStream contents inspect
and the result looks like:
Name of platform : ATI Stream Vendor of platform : Advanced Micro Devices, Inc. Profile of platform : FULL_PROFILE Version of platform : OpenCL 1.0 ATI-Stream-v2.0.0 Devices of this platform Name of device : AMD Phenom(tm) 9550 Quad-Core Processor Vendor of device : AuthenticAMD Vendor ID of device : 4098 Version of device : OpenCL 1.0 ATI-Stream-v2.0.0 driver version : 1.0 Device available : true Compute Address Space : 32 Device compiler available : true Device is little endian : true Error correction support avail. : false Size of global memory in cache : 65536 Global Memory cache line : 64 Global device memory : 1073741824 This device has NO image support !

or for my machine at work:

Vector Arithmetics - 0.7a
by admin on Feb.01, 2010, under Smalltalk
A new version has been published with new version of primitives - therefore you need both: the Smalltalk code and the new library.
With this version you have base arithmetics (+, -, *, /) and some mixture between scalar/vector and vector/vector operands.
Therefore you may now have code like:
| first second result | first := #(1 2 3) asMSKOSFloat64Vector. second := 2.0 . result := first + second. self assert: (result first = 3.0). self assert: (result second = 4.0). self assert: (result third = 5.0) .
or
| first second | first := #(1 2 3) asMSKOSFloat64Vector. second := 2.0 . first += second. self assert: (first first = 3.0). self assert: (first second = 4.0). self assert: (first third = 5.0) .
