Berkeley UPC supports operation on a wide variety of systems (including windows) however it does not currently support the use of a heterogenerous system to run a given job (beyond minor differences, such as slightly differing versions of the same Operating system, or different revisions of an x86 chip, etc). You're unlikely to find good support for heterogeneity in a shared-memory programming environment such as UPC or Global Arrays, because heterogeneity and shared-memory programming are somewhat at odds with each other (the system would need to somehow deal with issues like endianness conversion and pointer width adjustment under the covers). Even if there were such a system, the heterogeneity would likely induce non-trivial performance penalties such that you might not want to use it. These systems are designed primarily for scientific computing, where the standard practice is to use large homogeneous systems for reasons of simplicity and performance. Please direct further questions regarding Global Arrays to their support system: http://www.emsl.pnl.gov/docs/global/mailinglists.html Dan At 07:20 AM 9/4/2006, jagan jagan wrote: >Dear sir, > > Im Jaganath.A from India doing my project with regarding to UPC i was > very much disappointed by the news that UPC cant supprt heterogenous system. > I first preferred Global array but i coudnt install it on Linux and major > problem is doesnt support heterogenous system.
