solaris - What is your experience with Sun CoolThreads technology? -

-

my project has money spend before end of fiscal year , considering replacing sun-fire-v490 server we've had few years. 1 option looking @ coolthreads technology. know sun marketing, may not 100% unbiased. has played 1 of these?

i suspect no value us, since don't use threads or virtual machines , can't spend lot of time retrofitting code. spawn ton of processes, doubt coolthreads of there.

(and yes, money better spent on bonuses or something, that's not going happen.)

disclosure: work sun (but engineer in client software).

you don't necesarily need multithreaded code make use of these machines. having multiple processes make use of multiple hardware threads on multiple cores.

the old t1 processors (t1000 , t2000 boxes) did have single fpu, , weren't suitable tasks more 1% floating point. newer t2 , t2+ processors have fpu per core. that's still not great massive floating point crunching, more respectable.

(note: hyper-threading technology trademark of intel. sun uses term chip multithreading (cmt).)
