The Intel Xeon CPU E5-2650 is an SB-E chip released in Q1'12' so I would expect version 14.5 to support it. When you say the time it takes to 'open' solver manager (SM) after pre-processing is long,...

So it turns out that somehow my slow processing time is related to hyperthreading. Using CFX V13 with HT on, I could only get good speedups until 5 partitions on my 3930k cpu. 6 and above would kill...

I thought I would try with HT enabled and disabledon my i7-3930k and think I may have found my problem: HT Enabled: 1 core: 46s 2 cores: 19s 3 cores: 11s 4 cores: 9s 5 cores: 8s 6 cores:...

In fact, when I'm running sufficiently small jobs, it works quite well to run as many jobs serially as the cpu can track threads for, so 12 on the i7-3930k system. The performance hit comes when...

All I saw for the real partition number was just a number, 12, for my local machine. Or is that all I'm supposed to see, just the number of partitions that were used? Is there a way to actually...

I probably wasn't entirely clear on the network setup. I ran the simulation either exclusively on the single node on the cluster or on my local i7 machine. The partitions would have been difference...

The strangest thing about this is that the cluster, which is also V13, did not exhibit the same behaviour. I found this very odd since each core on the cluster is a 2.4GHz Xeon core with a Core2...

Replies: 16 Problem: Very long "write" time (~2h-3h) for results and transient results Views: 11,074 Posted By Shawn_A Problem: Very long "write" time (~2h-3h) for results and transient results I'm running a ~10M element simulation in CFX13 and my "write" times are incredibly long...talking 2 hours or more to write a 4GB results file. I'm running the job in 12-way parallel, all local on a 6...
