Hello, |
2 |
|
3 |
I need access to the latest gcc compiler for some experimental work |
4 |
with some GPU enabled coding. [1,2] |
5 |
|
6 |
So using this latest gcc compiler just for compiling some fancy new cluster |
7 |
codes using RDMA, is liable (probably ?) to be a wee bit tricky. |
8 |
Now, assuming I find an overlay somewhere, how do I go about ensuring |
9 |
it is slotted and only used with specific syntax just for a few codes |
10 |
and nothing on my general portage tree? |
11 |
|
12 |
Also, I have not found a gcc-5.0 or gcc-5.1 in an overlay (yet), but |
13 |
I did find this gcc-9999 by zorry[3]. It does not look to be gcc-5.x but I |
14 |
am as yet uncertain on that. |
15 |
|
16 |
Any discussion or suggestions how to best get access to gcc-5.x |
17 |
is most appreciated; as is methods to using it (control it) limited |
18 |
to just a few codes. |
