Comment on How to crop a pdf when using the ps2pdf converter via -dEPSCrop by Vasily Zhukovsky

Dear Lindon,

Thank you for your kind post. However, when I try to implement this on my .ps file it does not do as it did for you. It still gives me a pdf file with lots of white space and the figure in the bottom left corner of the page. Do you know what might be going wrong?

Comment on OpenMP Tutorial – firstprivate and lastprivate by Jung

I think, if you specify just private(x), the value of x in parallel loop is not initialized. Thus, x will have random floating number. On the other hand, firstprivate(x) will allow x to have a specific value, which is declared before a parallel region.

[…] But if I want automatic uploads to Dreamhost, I need additional setup. In particular, I need to create SSH keys and have them mirrored on my virtual server. This is where ssh-keygen and ssh-copy-id come in. […]

Only on Ubuntu, on Fedora
-lsatlas

Best to use pkg-config to find options:

ATLAS_CFLAGS=$(pkg-config –cflags atlas)
ATLAS_CFLAGS+=$(pkg-config –cflags blas-atlas)
ATLAS_CFLAGS+=$(pkg-config –cflags lapack-atlas)
ATLAS_LDFLAGS=$(pkg-config –libs atlas)
ATLAS_LDFLAGS+=$(pkg-config –libs blas-atlas)
ATLAS_LDFLAGS+=$(pkg-config –libs lapack-atlas)

that gets them on Debian and Redhat distro variants.

Thanks for the post! I also converted from R to Julia and I had yet to see someone implement a nice vim+julia REPL.

In this case, what is the difference between private and firstprivate? Do they not both start the parallel region with the value of the variable declared outside of the parallel block?
I.E., in your initial example, if you simple declared x private, did not assign i to x, then did a print of x, would you not get 44 throughout the entire parallel region? If so, then what is point of firstprivate?

Alternatively, does the first case just initialize the private instance of x within the parallel regions to 0?

Comment on Calling C++ from R using Rcpp by James

replications=rep(1,0,1) – this is a misleading part of the whole article, could you please change it to sth. else?

Also, i didn’t find the parad version faster than x/y – curious whether we are comparing 8cpus vs. 1 cpu?
