The main goal of MPFR is to provide a library for multiple-precision floating-point computation which is both efficient and has a well-defined semantics. It copies the good ideas from the ANSI/IEEE-754 standard for double-precision floating-point arithmetic (53-bit significand). (I think I asked that questions once alrady...)

[Pharo-project] Integrating Changes in 1.4 that require a new VM

Hi, Markus Denker wrote: ------------------------------------------------------------------------------------------------------------------------------ There are two changesets waiting for integrating in 1.4 that have serious consequences: - Ephemerons.

It's too long for a mail, but all explained here: http://smallissimo.blogspot.com/2011/09/clarifying-and-optimizing.html Optimizing such kernel message is important - for example when reading a file of floats... Which version do you prefer ? Shall comments be that long ? Any other opinion ? Nicolas

[Pharo-project] Smallspaces - Tuple Space for Smalltalk
by Dave Mason Sept. 22, 2011

Sept. 22, 2011

There is a reference on Wikipedia's page on Tuple Spaces to http://www.fongen.no/?docname=SmallSpaces/ but that is a dead link. I was interested in building tuple-space for Smalltalk, but this and a 1988 paper from Matsuoka and Kawai are the only things I turned up. If anyone knows more, please let me know. Also, I'd be interested to hear if people think this is a particularly good idea before I turn a grad student loose on it. Thanks ../Dave

[Pharo-project] jenkins cog - slow monticello on osx
by Tudor Girba Sept. 22, 2011

Sept. 22, 2011

Hi, Since a couple of weeks I am working with the Cog VM built on Jenkins: https://ci.lille.inria.fr/pharo/view/Cog/job/Cog-Mac-Cocoa/ Here is a little feedback. It worked quite well, the only problem is that Monticello is really slow in the Moose image. This means that even opening the Monticello Browser takes several seconds. I thought that this might be induced by something in the Moose image, but if I try with the Elliot's VM (2489), it works blazingly fast. Cheers, Doru -- www.tudorgirba.com "The coherence of a trip is given by the clearness of the goal."

Not run. > In any case, I am in favor to go ahead and change. > Moreover, I am not sure it is a big deal here, since it will not impact application code. The problems are: - people have to use the VM from https://ci.lille.inria.fr/pharo/view/Cog/ So older Vms (with more or different plugins, for example) are not possible. - there is no way to double check if a bug is specific to the Jenkins build Marcus -- Marcus Denker -- http://marcusdenker.de

[Pharo-project] [1.4] Doing a #condenseChanges in #14158
by Marcus Denker Sept. 22, 2011

Sept. 22, 2011

Hi, The .changes have gotten really large... (32MB...) So I will do a condense in the next update. NOTE: this will take quite some time to finish, so maybe wait for a pre-built image or Jenkins... Marcus -- Marcus Denker -- http://marcusdenker.de
