Hi, although SpectraST has a few multi-threaded features, I don’t think the msp conversion is multithreaded, so that is just one thread only. This conversion is actually not very CPU intensive at all, but rather I/O bound, i.e. the speed of your disks probably matters most. I’m guessing that on your cluster, you’re probably accessing the data over NFS, which can be quite slow. I also notice that often my laptop is faster at such operations because I have an SSD on my laptop and therefore disk reads and writes are really fast and that makes all the difference.
So, there are no parameters to make that operation faster. Running the operation on a faster disk might help a lot. Running it on a local disk, rather than on NFS might help quite a bit. But then there might be the overhead of copying the files to and from local disk. RAMdisk would be even faster. But, then, on the other hand, does it matter that much? Usually you’ll just have to do the msp -> splib conversion once, and then use that splib many times. So really the searching is more important because that’s happening many times. And I believe that part is multi-threaded. Not very helpful, but those are my thoughts..

I only build the stand-alone Spectrast on our cluster. The problem is that Spectrast runs quite slow on our cluster and the cpu usage is only 3%. I also try the same process on my laptop Windows, it is faster and finishes in only 200 seconds. The command I use is 'spectrast -cNtest test.msp'. Can anyone tell me how to solve it and is there any parameters I can set so that Spectrast can be used with multi processors? Thank you!
